About Y o u r S a f e t y :
Wo rking with wood is i n herently dangerous. Using hand or power too ls improperly or ignoring safety practices ca n lead to permanent injury or even death . Don't try to perform operations you learn about here (or elsewhere) unless you're certa in they are safe for
you . If something about an operation doesn't feel right, don't do it. Look for another way. We want you to enjoy the craft, so please keep safety foremost i n your mind whenever you're in the shop.
To Linda and our beautiful daughters, Rebecca and Sarah. Acknowledgments

RITING A BOOK IS A TEAM EFFORT
that requires the ideas,
support, and work of many people. Through this work, new
friendships are often forged and old friendships are deepened. With this in mind,
I
want to say thanks to the many people who helped me with
this project: Mike Foster of Freeborn Tools, for providing custom shaper cutter heads. Brian Boggs, for allowing me to photograph his steam-bending process. Helen Albert and Jennifer Renjilian of The Taunton Press, for their patience and encouragement. Andy Rae, for his ideas and critical feedback. Gary Rogowski, for providing photos. Jason Bennett, wood worker, friend, and patient stand-in, for many of the photos in this book. Most of all, I want to thank my wife and best friend, Linda. Without her love, patience, and hard work, this book would not have been possible.

Introduction

HAPE I S A FUNDAM ENTAL ELEMENT
of design. All furniture styles, even seemingly simple designs such as Shaker, use shape to enhance, increase function, and define style. For example, the sensuous curve of a chair back adds comfort as well as visual appeal, and the slender taper of a table leg creates light ness without sacrificing strength. Shape is critical to the ultimate success or failure of a piece of furniture. It simply can't be ignored. Before shapes can be created, they must first be visualized and then drawn. There are tools and templates available for drawing geometric shapes; but organic, freeform curves are often best sketched freehand. Fortunately, the natural movements of the wrist and elbow make it possible for anyone to draw flowing curves with a bit of practice. As I've illustrated in this book, the choices available for shaping are numerous. And it's not necessary to have access to a shop full of power tools, either. Many wood workers are rediscovering hand tools along with the pleasure and satisfaction that comes with their use. Planes, saws, chisels, and other edge tools all require patience and a degree of skill; but they yield a handmade look and texture as well as a deep sense of accomplishment.

Learning to tune and effectively use power tools can be satisfYing, too. And many power tool techniques, such as template shaping, yield efficiency that is unmatched with hand tools. Machines are also a good choice for many labor-intensive tasks, such as planing and sawing stock to size, provid ing more time for creating details by hand that machines simply can't duplicate. For example, a bandsaw is an efficient choice for sawing a curve in preparation for refining and sculpting the same curve with a spoke shave and a rasp. As a long-time wood worker who seeks pleasure from the craft, I've learned to enjoy both hand and power tools for what each has to offer. As you explore the pages of this book, it's my hope that you'll be inspired by the crea tivity and challenge that comes with adding shapes to your next woodworking project.
How to UseThisBook
F
IRST
OF ALL, this book is meant to be used, not put on a shelf to gather dust. It's meant to be pulled out and opened on your bench when you need to do a new or un familiar technique. So the first way to use this book is to make sure it's near where you do woodworking. In the pages that follow you'll find a wide variety of methods that cover the important processes of this area of woodworking. Just as in many other practical areas, in wood working there are often many ways to get to the same result. Why you choose one method over another depends on several factors:
TYiomuer.to ling. Y o u r s k i l level. The p r o j e c t .
Are you in a hurry or do you have the leisure to enjoy the quiet that comes with hand tools? Do you have the kind of shop that's the envy of every woodworker or a modest collection of the usual hand and power tools?
Do you prefer simpler methods because you're starting out or are you always looking to challenge yourself and expand your skills? Is the piece you're making utilitarian or an opportunity to show off your best work?
In this book, we've included a wide vari ety of techniques to fit these needs. To find your way around the book, you first need to ask yourself two questions: What result am I trying to achieve? What tools do I want to use to accomplish it? In some cases, there are many ways and many tools that will accomplish the same result. In others, there are only one or two sensible ways to do it. In all cases, however, we've taken a practical approach; so you may not find your favorite exotic method for doing a particular process. We have included every reasonable method and then a few just to flex your woodworking muscles. To organize the material, we've broken the subj ect down to two levels. "Parts" are major divisions of this class of techniques. "Sections" contain related techniques. Within sections, techniques and procedures that create a similar result are grouped together, usually organized from the most common way to do it to methods requiring specialized tools or a larger degree of skill. In some cases, the progression starts with the method requiring the most basic tech nology and then moves on to alternative methods using other common shop tools and finally to specialized tools.

The first thing you'll see in a part is a group of photos keyed to a page number. Think of this as an illustrated table of con tents. Here you'll see a photo representing each section in that part, along with the page on which each section starts. Each section begins with a similar "visual map," with photos that represent major groupings of techniques or individual tech niques. Under each grouping is a list of the step-by-step essays that explain how to do the methods, including the pages on which they can be found. Sections begin with an "overview," or brief introduction, to the methods described
therein. Here's where you'll find important general information on this group of tech niques, including any safety issues. You'll also read about specific tools needed for the operations that follow and how to build jigs or fixtures needed for them. The step-by-step essays are the heart of this book. Here a group of photos represents the key steps in the process. The accompany ing text describes the process and guides you through it, referring you back to the photos. Depending on how you learn best, either read the text first or look at the photos and drawings; but remember, they are meant to work together. In cases where there is an

The shaper, on the other hand, is consid erably more powerful than even the largest of routers. The motor and bearings of a router (the driving force for any machine) are no match for those of a shapero The shaper excels at shaping wide stock; its long spindle can reach high toward the center of a wide panel. A typical shaper cutter is, however, more expensive than the same profile in a router bit. So I use the router table for most smaller profiles, reserving the shaper for larger cuts.

Both the router and the shaper can flush trim and shape profiles on curves. But here's where a router has an advantage: Its small diameter bits and bearing guides can shape into tight contours where a shaper spindle and cutter won't fit. Although routers are capable of raising panels, the procedure typically requires three to five passes, depending on the density of the stock. This is because even the biggest routers lack the power for such a large cut. However, because of the larger spindle and

motor, even a small shaper can bevel the edges of a panel in one pass. Neither the router table nor the shaper can create a sharp inside corner. Mter shap ing with these machines, you'll need to carve the corner by hand. But you'll do less carv ing if you use a router. The small diameter of the guide bearings allows it to reach far deeper into the corner than a shapero
and shapers of their day. Both the sole and the iron of a molding plane are shaped with a reverse profile of the molding that is shaped. Each time the plane is pushed over the stock a shaving is produced and eventu ally the full molding profile is revealed. Molding planes range in size from a small quirk-bead plane to a large crown-molding plane that requires two men to power it one pushing and the other pulling. Many of these planes were produced in sets, such as hollows and rounds, tongue and groove, and rule joint planes for shaping the hinged joint of a drop-leaf table. Although no longer produced in large quantity, wooden molding planes are still available through antique tool dealers and

flea markets. Remarkably, many old planes are still in excellent condition despite their age and need only cleaning and sharpening to be put to use. Using wooden molding planes can be a quiet and romantic way to work wood. Although they may not be the tool of choice for shaping vast quantities of moldings, they can be an enjoyable way to produce a strip or two for a special project. And the unique textured surface that they create is unlike any produced by machine. The Stanley Tool Company introduced the first universalplane in the second half of the nineteenth century, when wooden planes were rapidly being replaced by new planes made of metal. The Stanley 45 and, later, the Stanley 55 were designed to replace a multi tude of wooden molding planes. As this type of plane evolved, its uses expanded, and it was advertised to be "a planing mill within itself." The Stanley 55 came equipped with four boxes of cutters, each ground to create a dif ferent molding profile. To accommodate the profiles of the various cutters, the plane had two skates, or runners, that adjusted both laterally and vertically. Other attachments included a third skate, two fences, and sever al stops to limit the cutting depth. Despite what some may say, the Stanley 55 is a working plane, albeit a heavy, awk ward one. However, most Stanley 55s that I've seen have needed tuning. The most common problem is that the two-piece skates were sometimes misaligned during manufacturing. A few strokes with a mill file will bring the skates into one plane. Also, the cutters must be sharp-very sharp-if
the plane is to work effectively. Using slip stones, hone the bevel and back of the cut ters as you would any plane iron or chisel. A scratch stock is simply a scraper with a molding profile. It's pushed or pulled along the edge of the stock to shape simple mold ings. The scratch stock is not practical for shaping large-scale profiles, but it is the tool of choice for shaping a small profile along a compound curve or for creating tiny details. Although you can buy a scratch stock, making one is easy and takes only minutes. An old, inexpensive marking gauge is a ready-made scratch stock. Just bandsaw a kerf in the beam and insert the blade. Making the blade is easy, too. Small pieces of bandsaw blade, scraper steel, or an old handsaw works well. You can easily shape the profile with small files. There are certain times when the only effective way to create a profile is simply with a chisel. Chisels come in a variety of sizes. Although intended for chopping join ery, the short length of butt chisels makes them easy to maneuver in tight spots when shaping intersections that are difficult or impossible to shape by machine methods. Firmer chisels are much longer than butt chisels and so provide extra leverage when panng. With their long pointed edge, skew chisels are the tool of choice for paring inside cor ners of raised panels, where routers and shapers can't reach. Although you can buy skewed bench chisels, the price is too high; it's easy and considerably less expensive to grind your own using ordinary bench chisels.

Tools for Carving
Carving tools are gouges and chisels that are available in a wide variety of sizes and shapes. To differentiate between the various tools, manufacturers use a numbering sys tem. If you browse the pages of a tool cata log, you'll find that the size and shapes of carving tools seem almost endless. However, many are specialty tools; most furniture
carving can be created with a little more than a dozen gouges of various sizes and sweeps. When selecting carving tools, look for full-length tools with thin steel and polished edges. Crude, thick-bodied tools are difficult to use and usually cost as much as those of better quality. Although some manufacturers now offer shorter, lower-priced carving tools

often labeled for beginners, I would avoid these tools. The short length makes them awkward to use. Tools for Turning
A lathe is totally unlike any other wood working machine; the cutting tool is held by the craftsman as the motor spins the stock between a pair of centers. As the stock spins, the shapes are created by rotating, pivoting, and levering the tool along the rest. Learning to turn takes time and patience. And it helps to have a good lathe-one that is heavy and balanced to reduce vibration to a minimum. Although most lathes today are made of cast iron, a wooden bed lathe allows you to lengthen it to suit your needs. A worthy, although expensive, option is a variable-speed motor. This feature allows you to adjust the speed quickly and easily to minimize vibration. When spindle turning parts for furniture, you need only a handful of tools. The rough ing gouge is a hefty tool with the end ground square. It's used for turning a square blank
into a round cylinder. Spindle gouges are ground with an elliptical pointed end. They're used for most shaping, including beads, coves, and vases or ogees. It's helpful to have about three sizes, such as % in., in., and 1f2 in. The skew, as the name implies, is a chisel with a skewed edge. But unlike an ordinary chisel, the edge is ground with a double bevel so that the tool can be worked in two directions. The skew has a steep learning curve but it's an important tool that shapes into tight areas where gouges can't. For the greatest flexibility it's helpful to have at least a 1f2-in. and a i -in. skew. I also have a heavy i 1f2-in. skew I use when turning bedposts. The parting tool is used for quickly sizing the various diameters on a cylinder before

shaping. Parting tools have a double bevel, and the best ones have a diamond -shaped shank to reduce friction. Tools for Bending
The vacuum press has greatly simplified the processes of veneering and bent laminations. No longer do you have to fuss with mating forms, cauls, and multitudes of clamps. A vacuum press uses atmospheric pressure to apply force to an assembly. The work is placed within a bag and the opening of the bag is sealed. Then a vacuum pump removes the air from the bag. The process is quick, simple, and hassle-free. Plus, the pressure inside a vacuum bag is uniform; so there's no worry that parts of the assembly lack suffi cient pressure. I can't say enough about the advantages of a vacuum press. Once you've

tried one, you'll find that there's no going back to the old methods. Building a steam box for bending wood is really quite easy. You'll need three items: a heat source, a container for the water, and a box to contain the parts as they are steamed. You can make the entire apparatus simply and inexpensively or you can spend some extra time and money to make it a bit more sophisticated. For many years, craftsmen have used wood for the steam box. But wood is heavy, absorbs much of the steam during startup, and will eventually rot. Nowadays, schedule 40 polyvinyl chloride PVC pipe is a better choice. It's lightweight, yet strong, resistant to heat, and impervious to rot. A portable camp stove works well for a heat source, especially if you already own one. But a better choice is the seafood cook ers available from most home centers. They burn propane, which is safer to use, and they provide greater heat to boil the water faster. An enclosed kettle or can may be used as a water container. Brian Boggs, a well known chairmaker in Berea, Kentucky, uses a pressure cooker heated over a gas stove. A length of radiator hose works well to pipe the steam to the box. It's flexible and obviously designed to withstand high temperatures . As a final note, as the steam condenses inside the box, a pool of lukewarm water will form and cool the contents. Avoid this sce nario by drilling a couple of drain holes and sloping the box slightly when you set it up.

finding local sources for quality lum ber can often be difficult. For exam ple, many lumberyards are stocked with boards that are stressed from being dried too quickly. In the rush to get lumber out of the kiln and into consumer's hands, kiln opera tors hurriedly push the lumber through the drying process. Often the result is boards that bear the scars of stress. Some of the scars are visible but others are not so easy to spot until you bring the lumber back to your shop and work it. Here are some examples:

is evident during ripping, when the lumber twists and warps imme diately upon passing the blade. As lumber is dried, it shrinks and develops different levels of stress from the core to the exte rior. Although all lumber undergoes stress during drying, the stresses become severe when the lumber is dried too quickly.

patronize it. As everyone knows, the lowest price isn't always a bargain. This principle applies to lumber as well. Dry Lumber
As lumber dries, it shrinks; and because it shrinks unevenly, it often warps. Obviously it's important to work with lumber after it has shrunk and warped. This way you can

straighten and flatten the stock with a joint er or handplane. So, how dry should the lumber be when you begin working it? A rule of thumb is 6 percent to 8 percent moisture content. This places the lumber in balance with most environments that have a relative humidity of around 40 percent, including most indoor settings. A common misconception is that only kiln-dried lumber is suitable for fine wood working. But what's important is not how the lumber was dried but that it has the cor rect moisture content and that it is free of drying defects and stress. You can successful ly air-dry lumber as long as the final stage of drying is done in an environment with a rel ative humidity of approximately 40 percent. This can be your shop, a garage, or even a spare bedroom. An inexpensive hygrometer will allow you to monitor the room's relative humidity accurately. When you suspect that the lumber may be dry, you can check it with a moisture meter. For the most accurate reading, cut a short segment from the end of a board and measure the core. Stock for Sawn Curves
Unlike steam-bent curves or bent lamina tions, the grain in a sawn curve doesn't fol low the curve. As a result, the short grain that occurs from sawing a curve weakens the stock. So when selecting stock for a sawn chair leg or other structural element, it's important to choose straight-grain stock for the greatest strength. Also, avoid stock with knots, because the grain is weakened around a knot. Save the wild and figured grain for A m o ist u re m eter a l l ows you to measu re the m o istu re content of l u m ber.

display in nonstructural areas such as table tops and door panels. After selecting the stock, orient the curved pattern to avoid short grain. Whether curved or tapered, legs are creat ed by sawing two adj acent faces of the stock. To avoid distraction and create visual har mony, it's a good idea to orient the grain to run diagonally across the end of the stock. Stock for Bending
Stock for steam bending should have clear, straight grain than runs parallel to the edges of the board. Wood that is steam bent undergoes extreme stress as it is stretched at the convex area of the curve and compressed at the concave area. If the grain runs out along the edges, the stock will splinter and break during the bending process. So it's important to select grain that runs parallel to

the edges of the board. When lumber is sawn from the log, often the grain is not parallel. Knots also weaken the grain. Because of this, a break will usually occur near a knot. There are two methods for creating stock with parallel grain. One way is to split the log into suitable sizes; a split naturally occurs along the grain. As you can imagine, this method is quite labor intensive. A more practical method is to saw the stock with the grain. You can begin with straight-grain stock that is oversize. Mark layout lines that run parallel to the grain and rip the stock to size on your bandsaw. Although it's important to select straight grain stock for bent laminations, it isn't as critical as stock selection for steam bending. Before placing stock in a curved form for laminating, the stock is planed to a thick ness that allows an easy, relatively stress free bend.

Stock for Panels
To cooper a panel, strips of wood are beveled along the edges and glued together in a curved form. To avoid the distraction resulting from mismatched grain, it's a good idea to use quartersawn stock. The grain in quartersawn stock is straight and easily matched. As an added benefit, it creates a more dimensionally stable panel.

Wide, flat surfaces give you the perfect opportunity to show off a prized figured board. The challenge it to keep it flat. Old textbooks recommend gluing narrow boards together to create wide panels. But this method yields an unattractive panel with plenty of gluelines and mismatched grain. I prefer instead to use wide figured stock for tabletops, door panels, and drawer fronts. In fact, I typically use only one board for tops of small tables, lids for slant front desks, and raised panels in doors. Often

the board may measure two feet in width. To keep the surface flat I follow these guidelines:
•
Avoid boards that contain pith; they always warp. Use only dry, stress-free lumber. If a panel releases moisture after you mill it to size, it will warp. Once the panel is warped, it becomes difficult or impossible to shape. Although it may not be practical for some woodworkers, I prefer to dry my own wide lumber. Allow the stock to acclimate. Bring the lumber into your shop several weeks before you plan to use it to allow it to adjust to the humidity. Use the construction of the furniture piece to keep panels flat. Once assembled into the framework of furniture, wide stock is restrained. For example, raised panels are trapped within a stile and rail frame, tabletops are fastened to a base, and desk lids have breadboard ends. To

Cutting Shapes UTTING SHAPES IS ESSENTIAL
to making furniture
because shape is the basis from which all other furniture design elements are drawn. In this part, you'll learned how to design and cut the basic geometric shapes of which furniture is composed:
• Rectangles and squares
are fundamental because all furniture ele
ments, even curvilinear forms, will fit within a rectangle.
• Tapers and octagons
are often used in subtle ways, such as in table
legs and bedposts.
• Circles, arcs, and ellipses
are used to relieve rectilinearity in bases,
frames, and mirrors and to create the familiar round tabletop.
• Geometrical curves
are used to create flowing curves for moldings.
Changing the radius alters the molding proportions .
•
Freeform curves
are associated with cabriole legs, chair backs, and
gooseneck pediment moldings on casework.

geometric shapes as well as freeform curves is essential to the design and construction of pleasing furni ture. To cut a shape, you first need to define it, which usually means drawing it. Although shapes can be drawn freehand, achieving symmetry and accuracy is easier with measuring instruments and templates. A straightedge is a template for ensuring that a line is straight and true. A ruler is nothing more than a straightedge with grad uated markings that enables us to measure and proportion rectilinear shapes. AND DRAW
Drawing Rectilinear Shapes
Knowing how to proportion rectangles (and series of rectangles) is essential to good fur niture design (see the drawing on p. 36). Because all furniture, even curvilinear designs, will fit within a rectangle (remem ber, an ellipse fits within a rectangle; a circle, within a square), proportioning a rectangle is a good starting point from which to design a piece of furniture. The Golden Rectangle has been used for centuries by designers and architects. In fact, the modern-day credit card fits within a Golden Rectangle. The proportions of the Golden Rectangle-l: l .6 1 8-are found throughout the natural world. The drawing at right shows how to draw a Golden Rectangle with a compass. Using ratios of whole numbers is another easy and effective method of proportioning rectangles. For example, index cards, photo graphs, and stationary all use ratios such as 3 by 5, 4 by 6, 7 by 9, and so on.

Waste area happens, cutting slows down and the blade heats up. The rule of thumb to follow is to select a blade pitch that places 6 to 12 teeth in contact with the stock. For example, 4 tpi used with 2-in. stock places 8 teeth in con tact with the stock. Thus the pitch is a good choice for the job. Jigs for Cutting Circles and Arcs
Making many circles or arcs of the same radius can require tedious clean up if they are all cut freehand. There are several useful jigs for cutting arcs, circles, and ellipses with your bandsaw or router.
When cutting a number of true circles, you'll find it helpful to use a jig that allows you to rotate the stock. An arc jig clamps to the bandsaw table to pivot the stock past the blade. When cutting small arcs, a curved fence can be used to guide the work.

Bevei i n g C u rved Edges Beveling the edges of curves is a centuries-old technique for making the stock appear thinner than it actually is. This deta i l creates a n i l lusion of l ig htness without sacrificing strength . The splat (the back center a rea) of the chair shown on p . 86 is a good example. The difficu lty is that the work of beveling a l l those tight, i ntercon nected curves is extremely tedious. To help speed the process, fi rst bevel the edges with a modified router bit.

The small base will
easily follow the curved surface of the splat, and the smal l-dia meter pilot on the bit reaches i nto the corners (D) . Before beginning the cut, adjust the depth so that the pilot of the bit just grazes the edges of the surface. After routi ng, you will sti l l need to carve the cor ners

three looks pretty challenging. Just thinking about it is hard enough, and getting the all those cuts in the right direction on the right face of the stock is even more so. But really, it's not as hard as it looks. The key is marking out carefully and working methodically, step by step. After all, compound shapes are just simple shapes put together. The rewards for your effort are new design possibilities and, in some cases-such as frame-and-panel work-better construction.

The Beauty and Function of the Frame and Panel
The frame and panel is one of the most important elements of furniture design. Its construction allows for seasonal wood move ment, yet it can usually be adapted to suit most any style or period of furniture. The most common use of frame-and-panel con struction is in doors. But it's also used for lids and even for the sides of casework. The broad appeal of the frame-and-panel design is its ability to overcome problems normally associated with seasonal changes in relative humidity. It works like this: A panel is trapped within a framework, yet the panel is free to expand and contract within that frame. This works because the thin edges of the panel fit within a groove in the frame. The frame gets its strength from the typical ly used mortise-and-tenon joinery. This pre vents the panel from warping or distorting without limiting its natural movement. Frame-and-panel design allows you to cover a large expanse, yet keep the space around the door small, because expansion of the door is limited to its framework.

Because the grain in the panel normally runs vertically, the top and bottom rails are made wider than the stile to prevent panel distortion. For visual balance, the bottom rail is typically made slightly wider than the top rail. There are exceptions to this rule of thumb, however. For example, doors with an arched panel require a wide top rail to accommodate the arch. In this case, the remainder of the rail after cutting the arch is typically equal to the stile width. Visually speaking, rectangular panels are more attractive than square ones. For this reason, square openings are usually divided into two doors (or one door with two rec tangular panels). Otherwise, I like using a numerical proportioning system for calculat ing door size. Once I've settled on the overall dimen sions and proportions, I turn my attention to visual details. The most common panel edge is a flat bevel. But the edge can also be a

curve, ogee, or a simple bevel. The panel shape can be square, arched, tombstone, or cathedral. Once completed, the overall effect of the design is strong, so I'm careful to chose details and proportions that comple ment rather than compete with the overall design of the piece on which the panel is to be used. Panel-Raising Jig for the Table Saw
Panels can be raised with any number of methods: with a shaper, on a router table, or by hand. Without a doubt, the shaper is the most efficient tool you can use to raise panels. But shapers are expensive and routers lack the power to cut the profile in one pass. Because of these limitations, for many woodworkers the table saw may be the best option. Most woodworkers own table saws and the machine can easily make the cut in one pass. To set up your table saw for panel raising, it makes sense to build a jig. Of course you can instead tilt the blade and guide the stock with the fence. But the fence on most saws lacks sufficient height to provide good sup port for the panel. This jig overcomes the support problem and offers other advantages as well. The broad surface area of the jig provides plenty of support, and the bevel angle is built in. So there's no need to tilt the blade and check the angle. Each time you use the j ig, you'll save time. In addition, it's safer than using the fence. One final note: Construct the jig so that it fits in your saw's miter slot instead of just following the fence. This will prevent the jig (or work) from coming in contact with the back of the blade and causing kickback.
Tombstone Doors
Frame-and-panel doors can take on myriad designs. But certainly one of the most ele gant examples is the tombstone door. A centuries-old design, the tombstone door is from a period when all woodworking was done by hand. Today, despite the beauty of the design, tombstone doors are not often seen. I'm sure that one reason is that the inside corners that flank the arch must be T A B L E - S AW PA N E L - R A I S I N G J I G

This process isn't really difficult-just a bit time-consuming. If you would like to incorporate tomb stone doors into your next project, there are several designs from which to choose.

Door Joinery and Structural Strength

Router bits and shaper cutters are available in several profiles, making it easy to achieve traditional door frame joinery. Cope-and stick joinery is actually quite a simple con cept. A profile is milled on the inside of the door stile (the vertical member), and its reverse profile or mirror image is milled on the rail (the horizontal member). In the process, a short tenon is formed that fits into the groove created for the panel. The draw ing below shows a typical cope-and-stick router bit set. Single reversible bits are somewhat cheaper, but they can be fussier to set up. Cope-and-stick joinery is fast and effi cient and is best used when you have a large number of doors to make, say, for a kitchen. But this method of construction is not as strong as a traditional mortise-and-tenon

to the previous one, success is virtually ensured. First, design your door. The drawing at right shows the structure of a typical sash door. Once you've drawn a plan for your door, mill your stock to the correct width and length. Mark your layout on the stock using a sharp pencil with a hard lead (no. 4) to get an accurate reference mark. Your mark needs to be exact, so use a very sharp pencil. After the initial sharpening, sharpen the pencil to a chisel edge with very fine sand paper. Carefully measure and mark the loca tion of each joint. As you cut your profiles, check and double-check to make sure your setup is accurate.

Compound Curves Are Much Easier T han T hey Look
A compound curve flows in two directions simultaneously. Although the sculptural look appears difficult to execute, the technique is really quite easy. First bandsaw one face of the stock; then saw an adjacent face. When you've finished bandsawing, much of the effect has been achieved. The remaining handwork involves smoothing and blending the curves. Probably the most familiar example of a compound curve is the cabriole leg. But you can see the influence of compound curves in many furniture styles, including contempo rary pIeces.

When designing furniture with com pound curves, I find it necessary to build a prototype. It's very difficult to completely judge the curves and proportions by simply looking at a drawing (though it's a great place to begin). After sketching the design on plywood, bandsaw the curves to create a pattern. Then choose some inexpensive wood and model a prototype. Trace the pat tern onto two adjacent surfaces. Next, band saw the outline on the first surface. Then tape the offcuts back in position and saw the second face. After sawing, smooth and fair the curves with a spokeshave or rasp, depending on the tightness of the curve. As you work, examine the curve for irregularities. When you're sat isfied with the lines, begin sculpting and blending with a rasp. As you sculpt, follow the outline you've already established. Careful study of the prototype is one of the keys to success. When you're finished

modeling the prototype, stand it on you bench for critiquing. This stage of the process is crucial; it gives you the opportuni ty to check out the design before commit ting it to a piece of furniture. I like to view the prototype from all angles, as I examine the curves and proportions. Usually, you'll find areas that need improvement. Perhaps the curve is too pronounced or maybe a dimension is disproportionate. If this hap pens, you'll be glad that you took the time to create a prototype. Complex Designs Requ ire Careful Planning
Asymmetrical compound curves (such as the chair arm and post in shown on p. 87) are a true test of a furniture maker's skill. Balance, curve, and proportion are critical for the piece to be visually successful. Added to the complexity is the joint where the arm and post meet. But a logical approach to the
88 I
Com p l ex S h a p e s
problem combined with a systematic order of events help you avoid major setbacks. For example, I usually prefer to cut joints before bandsawing curves. If the stock is straight and square, it easily registers against the milled surfaces of my machines. But this isn't always practical-or even possible with curved elements. Although I cut the tenons on the arm post before sawing the curves, I use an opposite approach on the arm itself Otherwise, the stock is too wide to fit within my benchtop mortiser. Also, sometimes it's easier to cut the joint by hand than to consume time with an elaborate machine setup. Unlike most compound curves, asym metrical curves require two patterns. In fact, the arm in this example uses three patterns: top, inside, and outside. Mter the patterns are traced onto the stock, extra care is needed when sawing the side. Following the pattern precisely on one side will result in a miscut on the opposite side. But if you take time to plan the cutting sequence, you can avoid spoiling the work. You'll also find on this type of work that the bandsaw is really useful only for remov ing excess stock. Afterward, you'll need to shape the surfaces by hand with gouges and a rasp to remove stock in areas that the saw couldn't reach. This is the enjoyable part of the work-and the part that creates the details you can't match with machine work. Finally, before I commit time and expen sive stock to such a lengthy process, I model a prototype. Sculpted furniture parts are difficult to conceive without a three dimensional model.
Raised Panels on the S h a per If you ' re shaping a n u m ber o f panels, t h e shaper is defin itely the tool of choice. Most shapers have a hefty spindle and powerful m otor, which enable you to shape a panel i n one pass. Use a box fence to shield your hands from the cutter. As a n added benefit, the cutterhead open ing i n the fence is sma l l . This prevents the work from tipping i nto the cutterhead, which can pote ntia l ly cause a kickback. Beg i n by mounting a rub bea ring u nder the cutterhead . This provides additional support for the stock and aids i n setti ng the fence. Mount the cutterhead over the bea ring and lock it i n place with the spindle n u t . Next, adjust the height of the cutterhead

Then secure the
fence (8) . Use a stra ig htedge to position the fence ta ngent to the bearing and cla mp the fence firmly i n place . Finally, adj u st the front of the box fence for the panel thickness (C) .

Raised Panels o n the Router Ta ble Shapers a re expensive a n d have a steep learning curve to master. So if you a l ready own a router ta ble, it makes sense to use it to s hape pa nels especia lly if you ra ise panels only occasional ly. Depending on the density of the wood you ' re shaping and the size of your router, you ' l l need to make the cut in two to five passes. This prevents the router from overheating and s h utti ng down. To set up the router table, first mount the bit securely

Note that the u n ique design of a box fence com pletely surrounds the cutterhead to keep hands safe . It also directs the s havings toward the dust collector. Before con necting the router to a power sou rce, make certa in that the fence is clamped firmly and that the bit clears the fence.

placed. Stop blocks are fastened to the jig in various locations to register the work and counteract the forces of the cutter. Although toggle clamps are quick to operate and work well, they can't be used when the work is to be shaped along with the entire perimeter. But they're a great choice when the work is to be shaped only along one or two edges. Fasteners, such as small nails and screws, are also useful for securing work to a tem plate. They hold well and are quick to install and remove. Of course, fasteners leave an unsightly hole in the work, so it's important to position them where the hole will be either hidden or later cut away. Also, it's cru cial for safety to position any nail or screw well out of the path of the cutter. Although double-sided woodturner's tape holds well, it's my last choice for securing a template. It's time-consuming to peel the paper from the tape and stick it in position.
But when the work is to be shaped around the entire perimeter and it's impossible to hide the hole from a nail or screw, then tape is a good option. Avoid carpet tape, how ever, because it lacks the strength of the cloth woodturner's tape. Also, never use tape for heavy cuts with the shaper; limit its use to small cuts on the router table. Making a Template from a Template
Sometimes when making furniture it's nec essary to match the curve (or a similar curve) on an adjacent element. The base, or seat board, is curved and above the seat board are drawers and dividers that must match, but they are stepped back. Matching the three elements-drawer, seat board, and divider-can be somewhat tedious.

Here's the method I use: Stack several layers of thin plywood together to equal the thickness of the seat board. The top layer of plywood is actually the template for the seat board; the bottom layer will become a tem plate for the dividers and drawers. Next, shape the stack with the same router bit that was used for shaping the seat board. After ward, separate the plywood layers; the bot tom layer is now a perfectly shaped new template. To m a ke a tem p l ate from a templ ate, fi rst stack plywood to e q u a l the th ickness of t h e p i ece to b e s h a pe d .

Carving the Corners
No discussion of template shaping would be complete without examining the technique's major shortcoming: You can't use it to shape inside corners. As router bits and shaper cut ters spin, they cut in an are, which is left indelibly on any inside corners. One solution is to design furniture that is void of shaped inside corners. But this often results in fur niture that is void of detail and interest. I prefer instead to shape or carve the corners by hand once the machine shaping is com pleted. It usually takes just a few minutes, and the results are well worth it.

Cutt i n g with Tem pl ates on the Tab l e Saw The table saw ca n be used with a template to c ut odd-s ha ped, straig ht-edged components. A good example is the s helf from a corner cabinet. Begin by preparing the template and guide. A piece of 1,I.z-i n . plywood is of sufficient thickness for the tem plate; the guide must have a long, stra ight edge that is suspended over and parallel to the blade (A) . Once the setup is ready, attach the template to the workpiece. To make the cut, the template is pushed along the guide as the excess wood is cut from the stock to create the desired shape (8).

Edge Treatments and Moldings DGE TREATMENTS AND MOLDINGS
have been used for
centuries to add embellishment, detail, and visual interest to furniture. It's difficult to imagine furniture without mold ings, because even the simplest styles, such as Shaker, use beads to soften edges and create interesting shadow lines. That's why an understanding of edge treatments and moldings is so important to furniture design. An edge treatment or the addition of even a simple molding can turn a boring box or a utilitarian table into a piece of beautiful furniture. An edge treatment can be as simple as breaking the sharp 90-degree angle with a few passes of a block plane or cutting an ogee profile with a router or shapero Simple moldings are easy to create with the wide variety of router bits now available. Even complex and built-up moldings are just a matter of combining basic shapes to create different effects.

H E N T H E EDGE OF A TAB LETOP
OR D WER F RONT is shaped, it creates the same visual effects as a strip molding. But shaping an edge yields additional benefits; the square corners are removed, the resulting edges are softer to the touch, and the problems of wood movement associated with applied moldings are nonex istent, because the edge is part of the origi nal stock. Undoubtedly, the simplest edge treatment for tabletops is the roundover. By shaping a small radius on the edges, you remove the hard look and feel of the corner. The effect improves with age as the surfaces wear unevenly, creating a worn look. To create the worn look artificially, you can work the rounded surfaces with a file. Another attractive table edge is the reverse ogee. The concave-convex profile creates an edge that appears thin and deli cate. When designing an ogee edge, you can alter the effect by changing the center-point locations. The possibilities for edge treat ments are broad, because router bits and shaper cutters are available in a wide variety of profiles.

You can also bead the edges of drawer fronts made from solid stock. The bead can be shaped into the front with a plane, router, or scratch stock. If you choose to shape a bead on the ends and edges, you'll need to miter the corners with a chisel.

The edges of doors and drawers can also benefit from simple treatments. Adding a bead is a great way to frame the perimeter of flush-fitting doors and drawers. If a veneer is used on the faces, the bead will protect the fragile edges from chipping. You can add the bead after veneering; just cut a shallow rab bet around the drawer perimeter and miter a thin beaded strip.

Almost any profile can be used on door and drawer edges. One popular and tradi tional profile is the thumbnail. It's most commonly used with lipped doors and drawers. A rabbet is cut around the inside perimeter, and the door or drawer front is fit within the opening. The lip that remains is shaped with a thumbnail profile. The result is a door or drawer that covers the opening, yet the edge is thin and refined. Shaping the Entire Edge
The most efficient tools for shaping edges are the router table and shapero Doors, drawers, and smaller tabletops are easy to handle when feeding through the machines. But large, awkward work is easier to shape with a handheld router. When shaping the edges of round or curved tabletops you'll need to use a bit or cutter with a bearing to guide the cut. If the edge is partially shaped, the bearing can fol low the remaining portion of the edge. However, if the entire edge is shaped, you'll need to make a template to guide the cut.

Still another form of molded edge treat ments is the dished top. The surface of the top is recessed, and the raised rim is molded. If the top is rectilinear, it's simple to add a strip of molding to the edge and miter the corners. But if the top is round, the molding and top are easier to shape as one piece. Dished tops were popular on eighteenth century tea tables and candle stands. The traditional method used is to turn the top on

A floor-stand tool rest is needed to support the tools during the turn mg process. These days, a more efficient method for dishing circular tops is with a router. A jig is used to suspend the router over the top, and the router is held stationary while the top is rotated in the jig. A straight bit is used to dish the flat interior, and profile bits are used for the molded edge. Afterward, the interior is scraped and sanded smooth.

S h a ped E d g e with a H a n d held Router One of the advantages of a router over a shaper is that it is lig htweight a n d portable. Profi ling the edge of large, awkward stock such as a tabletop can be d ifficult without a hel per-but with the router it's a snap. The chamfer shown here is just an exa mple of the many edge treatments you can cut with a router. First m i l l the stock to size and clamp it to your workbench. If you ' re creating a large cha mfer, you may want to shape it in two passes. Otherwise, set the bit for the req uired cutting depth and g u ide it a round the perimeter of the top in a cou nterclockwise d i rection. To avoid u nsightly tearout on the edges, shape an end first (A) and slow the feed rate as you approach the
corner. As you fin ish with the sides (8), any s l ight tearout will be shaped away.
S h a ped Edge o n t h e Router Tab l e The router ta ble has replaced the sha per for most small tasks. Shaping a cha mfer with the router ta ble is a prime example. Begin by adjusti ng the bit height (A) and set the fence tangent to the guide bea ring on the bit ( 8 ) . Then, starting with a n end, feed the stock from right to left (C) . When shaping the ends, slow down the feed as you approach the corner to avoid excessive tearout. When you shape the edges, any m i nor tearout will be shaped away (D) .

E ntire Edge S h a ped on the S h a per Many attractive edge profiles, such as a n ogee, involve shaping the entire edge. When shaping the entire edge, part of the stock width is removed.

In other words, the out feed fence m ust be ta ngent to the smal lest cut ting dia meter of the cutterhead. Begin by adj usting the spindle height (A). To make the fence adjustment, first shape enough length of stock to reach the outfeed fence. N ow turn the s haper off.

·',.:.,'3-14):",'.,._Shaping the molding is much the same as truing the peri meter: Start the router, clamp it in posi tion, and rotate the top ( H ) . To ens ure that the molding isn't squeezed, begin from the outside edge and work i nward ( I ) . The mold ing is shaped in th ree steps: outside edge of bead; inside edge of bead; and cove, which is shaped with a bull nose bit. Once the mold ing is complete, switch back to the straight bit to dish the top
(J) .
This process
goes quickly, beca use there is no careful position ing of the router as there was with the molding. If you have a hel per, one of you can hold the router while the other rotates the top, which sidesteps the process of clamping the router for each cut. With the router work completed, you ' re ready for the ha ndwork. Clamp the top to the bench and scrape the s u rface smooth
(K).
Use care to avoid
scarring the molding. After smoothing the top, the edge will need shaping along the u nderside to remove the square corner. This step also gives the top a thin, refined appeara nce. A rasp works we l l for this process, but first draw a l i n e with a compass for use as a guide. Now secure the top i n the vise and rasp the edge (L) . Work the sur face from the fil let at the bead to the layout l i ne. When you ' re satisfied, smooth the edge with a file, scraper, and then sandpaper.

molding profile than the bead. A bead is a semicircular or semi-elliptical profile. It can be shaped flush along the edge of a table apron or proud around the perimeter of a drawer front. Used along the edge of backboards in casework, the bead will embellish the back while hid ing the expansion joint between the boards. Beads are easily shaped with a router, plane, hand beader, or even scratch stock. VERSATILE
Undoubtedly, it's this versatility and ease of use that has made the bead so popular for centuries. Next time you need to soften a hard edge or add a bit of decoration, remember this simple, versatile profile. When shaping beads, remember that you need to get to the full depth of the cutter's profile to achieve the right shape. Beads that aren't cut to full depth can appear flattened on one or more sides.

A scratch stock is simply a scraper with a profile. By pushing the tool across the wood surface, you produce a molding profile. Why use a scratch stock instead of a router? There are several reasons. A scratch stock can shape tiny profiles that a router can't. Also, a scratch stock can easily shape a pro file along a freeform curve. Plus you can customize the shape to suite your design requirements.

LL MOLDINGS,
even seemingly com plex ones, are made up of shapes derived from about a half dozen basic profiles: bead, thumbnail, ovolo, ogee, chamfer, and cove. Simple moldings typi cally use just one of these profiles, whereas complex moldings use a number of them. By mixing sizes and variations of the basic pro files, the options become nearly endless. Moldings are integrated into furniture in one of two ways: a strip of molding is

Stock Selection for Moldings
Strip moldings are shaped on lengths of straight-grain stock and then attached to the work with glue and/or fasteners. Strip mold ings can consist of one or more profiles shaped onto a single wood strip or several strips joined together to make a wide and/or deep complex molding . It's best to select straight-grain stock when making strip moldings. When using hand tools, such as planes and scratch stock, straight-grain stock will produce less tearout.

When using machines, it's often necessary to shape a wide board and rip the molding free afterward. This method will keep your hands a safe distance from the cutter or bit. If you select straight-grain stock, the strips will be less likely to distort when you rip them free. Also, when milling stock for strip mold ing, it's a good idea to make extra for a mis cut or other any other problem that may occur. Otherwise, if you need another piece it can often be difficult to mill it for an exact match to the original-especially if the molding is a complicated design made from several profiles. Attaching Moldings
When attaching moldings, it's helpful to follow a few guidelines to ease the process. Parallel strips-such as those that wrap around a table edge-must be of the exact same length for the miter to fit. This is easily accomplished by using a stop on the miter saw. When fitting molding to casework, it works well to miter the front strip first and then the returns or side strips. If adjustments need to be made for a precise fit, they can be made to the returns. Afterward, the ends of the returns are cut 90 degrees to be flush with the case back. One of the most important points to remember when attaching strip molding is to allow for cross-grain seasonal wood move ment. Small moldings can be effectively fas tened with brads, which are set below the wood surface. As the wood moves, the soft brads will flex. Large moldings, such as a crown molding on casework, can be fasten with screws from the inside of the case.

Remember to slot the holes in the case so the screws will be able to slide as the case expands and contracts. Always use glue in the miter joints of moldings; it keeps the joint closed tight through the years.

Using Hand Tools to Create Moldings
There's something addictive about making moldings with hand tools, watching the shavings pile up like confetti. It's quiet work; and for period projects, you get the tool marks and slight imperfections that lend an authentic look. For small moldings, you can use a scratch stock. Molding planes were once made in an amazing variety of profiles; When u s i n g h a nd p l a nes o r a scratch stock to cut mold i n gs, a lways sel ect stra i g ht-g ra i n stock to avoid tearout.

The so-called universal plane-the Stanley 55-was developed around the turn of the twentieth century to replace a multi tude of wooden planes. Although it's some times a useful tool, it's too impractical to be the "planing mill within itself," as it was originally claimed to be. However, it is an enjoyable tool to use and can create many profiles. Whenever you use hand tools to cut molding, be sure to choose straight, even grain stock to reduce the possibility of tearout. Keep the blades sharp by using rounded files and polishing with slipstones.

Why use a molding head when the router ta ble is just a few feet away? When shaping the face of a board, you a re not l i m ited by the board's width when you use a mold i n g head in the table saw. This is a disti nct advantage when shaping wi ndow trim and other wide stock that is beyond the reach of a router bit. The first step when using the head is to lock the cutters securely in position (A) Head styles vary so read and fol low the man ufacturer's instruc tions careful ly. Next, mount the head on your table saw (8). Make certa i n that the head spins freely and fits with i n the throat plate opening. It may be necessary to add a spacer to center the head (C) . Lower the head for a light cut. The next step is to position the fence and clamp a featherboard in place to hold the stock firmly to the table ( D ) . Now you ' re ready for a trial cut; a quick check of the profile depth and you ' re ready to begin.

S i m ple M o l d i n g with a Molding Plane Wooden molding planes have been a round for centuries. Despite the a rray of power tool s avail able, the wooden plane is sti l l an effective and enjoya ble tool for shaping moldings. Molding planes a re readily ava i lable from tool dealers and flea ma rkets; if you've never experienced the pleasure using them, I encourage you to find one and give it a try. Stock selection is im portant; wooden molding pla nes are l ightweight and work best on stra ight grain stock. C heck the i ron for sharpness and set it for a light cut (A) . Most asym metrical profiles ( l i ke the ogee in this example) req uire that you hold the plane at an angle in relationship to the work. As an aid in gauging and maintaining the correct angle, planes usually have spring lines scribed into the front end of the plane (8). As you begin each cut. keep the spring l i nes parallel to the stock and the fence in contact with the edge of the stock (C) . When you reach the full depth of the profi le, the stop wi l l contact the surface of the work and pre vent the plane from cutting farther

Next, set the second skate in position flush with the cutter or slightly inset (8) Then slide the fence onto the arms and lock it in place with the thumbscrews (C) . When shaping asym metrical profiles such as this ogee, it works best to position the cut i nward slightly from the edge of the stock. This way, the cutter wi l l be trapped by the stock as you plane, which prevents it from slid i ng off of the profi l e . N ow you ' re ready t o make t h e cut. Keep the fence agai nst the stock with one hand and push the plane firmly with the other (D). As the shav ings peel away and the profile is revealed (E). set the pla ne's stop to bear agai nst the stock (F). The stop will ensure that all subsequent moldings a re identical i n profile depth .

of two or more simple pro files. They are used when a more dramatic or formal look is desired. A typical example of a complex molding is the crown molding on most casework. Generally, a crown consists of a large cove flanked by smaller profiles, such as a thumbnail, bead, or ogee. As the molding steps upward, it also steps outward to "look down" toward the observer. Waist moldings on casework are another example of complex moldings. Chests, clocks, desks, and other tall pieces are usu ally constructed of several cases or "boxes." To unifY the cases, a waist molding is used at their junction. There are three options for making complex molding: shaping thin, flat stock and attaching it to the case at an angle,

"--- Thumbnail cult to apply; it's awkward to align the molding and attach it. In addition, if the molding isn't capped off, it will need to be supported by triangular glue blocks. The main advantage to this method is that it avoids using thick stock. To shape wide, flat stock you'll need a shaper with a long spindle, some molding planes, or a table saw molding head. Unfortunately, a router can't reach to shape wide stock.

The second method of shaping a complex molding uses thick stock. This method works well when a large, elliptical cove is the centerpiece of the molding. First, the cove is cut on the table saw; then smaller profiles are shaped on each side of the cove. Because it's shaped from thick stock, the molding is self-supporting and easier than flat stock to apply to a case. It appears more finished, too. This can be especially important when the case is short enough to view from the

� Using Dentil Molding for a Formal Look
One of the most versatile complex moldings is dentil molding, essentially a strip of wood with a series of cuts that leave blocks. These blocks resemble teeth, giving the molding its name. Because the cuts are shallow, the teeth remain intact; it's much easier to work with a strip of evenly spaced block than with dozens of individual blocks. But the blocks, or teeth, appear individual because the upper

portion of the dentil molding is hidden by another applied molding. The whole process of laying out, cutting, and applying dentil molding is a bit time consuming. But the result is certainly worth the extra effort. Using dentil molding is an easy way to add formality and distinction to almost any cornice. There are several options to choose from when designing a cornice with dentil mold ing. For example, you can leave the bottom of each cut flat or you can carve a convex

arch into each one. Another option is to drill a series of shallow holes above the spaces. This adds additional detail, which gives the molding more distinction. Spacing and proportion are also impor tant. The blocks look best if each is a verti cal rectangle rather than a square. The pro portion of the blocks should fit with the rest of the cornice, whether it's an arrangement of small profiles for, say, a clock case or a large group of moldings in an architectural cornICe. Finally, dentil molding looks best if the miters meet at blocks rather than at a space between the blocks. To space the blocks accurately you'll need to lay out the den til strip with dividers before you begin cutting.

UILDING CURVILINEAR FURNITURE
presents many challenges, one of which is shaping curved moldings to match the contours. To shape curved mold ings successfully it's important to understand the type of curve so that you can approach the problem logically. For all practical pur poses, curved moldings fall into four broad categories: arcs, S curves, elliptical curves, and compound curves. Arcs are segments of true circles. Arched moldings are used over semicircular doors and openings on casework, such as clocks, desks, and chests. There are two methods for shaping arcs: First you can shape from the edge with a bearing to guide the work and limit the cut ting depth. The second option is to shape the molding from the face with a curved cradle to support the stock. The decision of which method to use is determined by the width of the molding and the shape of the profile. It's much easier and less time con suming to shape the work from the edge; however, if the molding is wide, it's safer to shape from the face and limit the amount of exposed cutter. Also, some profiles, such as a quirk bead, can't be shaped from the edge. Moldings that follow an S curve are usu ally referred to as "goosenecks" and are used as pediment moldings on casework. Goose neck moldings can be shaped from the edge with a shaper or the face with a router. Again the determination is made by the molding profile and its size. If shaped from the edge, a template jig is necessary to guide the cut and position your hands a safe dis tance from the cutterhead. If you use the router, you'll also need to first construct a jig to guide the work. The

Compound curves flow in two directions simultaneously. Moldings that follow com pound curves are usually limited to simple profiles, such as a quirk bead along the edge of a chair back. By far the most practical method for shaping a molding profile on a compound curve is with a scratch stock. Depending on the sweep of the curve, it may be necessary to curve the face of the scratch stock.

It can seem puzzling-how do you miter the end of a molding with an S curve? It's actu ally quite easy. Here's how to do it. When building the template, extend it in a straight line beyond the point at which the molding will later be mitered. This creates a flat sur face to register on the table of the miter saw. But you have only one chance to cut it, so it must be accurate. First position the molding on the pediment and mark the miter loca tion. Next, make certain that the saw is cut ting a precise 90-degree angle. Now position the molding on the saw and make the cut.

By using a complex cutter and a te m plate/j ig to hold the stock, the profile can be shaped clea n ly i n just a few m i n utes. Before shaping, you ' l l need to build a template/j ig to hold the stock and g u ide the cutterhead in a curved path. Select a piece of %-i n . plywood for the jig that's wide enough to position your hands a m i n i m u m of 8 in. from the cutterhead and long enough to extend several inches beyond the stock.

I used th ree bea ring sizes with this cutterhead; the smal lest bea ring a l lows the cutterhead to shape the full profi le. Also, notice that I ' m using a disk guard that mou nts a bove the cutterhead. This guard is ava i lable from Delta.

G ooseneck M o l d i n g on the Router Ta ble with Pin J i g Another method for shaping gooseneck and a rched moldings is to use a pin router. A p i n or bearing is suspended over the router, which is mou nted i n a table. A template, which is posi tioned over the stock, fol lows the gu ide pin . Beca use the pin can be positioned offset to the router bit, i nterior cuts can be made . Although pin routers a re expensive, the j i g shown here cla mps to the edge of you r router table to convert it to a pin router. A bea ring is fastened to the end of the a rm to g u ide the template (A) . The arm is held in position on the base with a bolt. A tongue under the arm slides within a groove in the base to prevent the a rm from moving sideways (8)

After constructing the jig, make a full-size pattern of the gooseneck curve . Next, use the pattern to lay out the curve on both the template and the stock. Extend the l i ne on the template beyond the curve of the molding. Th is way the template will contact the bea ring before the router bit con tacts the stock, eliminating potential grabbing at

Begin by flush tri mming the work (C) with a flush-tri mming router bit (D); you will not need the pin jig for this step. Next, begin shaping the cove. Because of the large size of the cove, it's necessary to make this cut in several passes. Mount the corebox bit i n the router and clamp the jig to the ta ble edge. Now s l ide the arm of the j i g out and lock it in position for a light cut Before starting the cut, you m ust rea lize that it's necessary to keep the template edge i n the same spot on the bea ri ng throug hout the cut; the location is a poi nt ta ngent to the bea ring at
90
degrees to the arm. This is necessary because
the guide bearing and bit are not spinning on the same axis-they are offset Performing th is task is not difficu lt, but req u i res concentratio n . Also, rea lize that you ' l l gain experience as you go and keeping the tem plate located properly is not extremely critical until the final pass. Let's give it a try. Tu rn on the router, position the end of the template agai nst the bea ri ng, and begin feed ing the stock
( E , F) .
As the template
curves, rotate it to maintain contact at the front of the bea ring (G, H, I ) . N ow turn off the router, retract the a rm slig htly, and repeat the process several times until the full profile of the cove has been shaped (J) . (Text continues on

Other Decorative Shapes S VERSATILE AS ROUTERS
and shapers can be, there
are times when some ingenuity is necessary to achieve a certain profile or shape. Cove cutting is a prime example. Large coves are often beyond the reach of all but the biggest shaper, and the profiles are limited to the cutters available. Fortunately, this shape can easily be cut on the table saw, producing coves of different sizes and arcs that are particularly useful in making crown molding. Fluting and reeding have a special place in period furniture and archi tectural woodworking. Well-designed and proportioned flutes and reeds in a pilaster or column lend a formal, elegant look to a piece of furniture or a period room. Although cove cutting, fluting, and reeding are decorative techniques, their utility cannot be underestimated. They can turn an ordinary piece of furniture into something distinctive.

but perhaps their greatest use is in mak ing moldings. Many large, complex moldings for furniture, casework, and archi tectural cornices use a cove as the main pro file. The cove is usually flanked by smaller basic profiles, such as an ogee or thumbnail. The problem when making this type of molding is always how to cut a large, deep cove. Even the largest router bits cut a rela tively small cove-and large shapers and molders are beyond the price range of most small shops. The table saw provides a viable solution. Probably one of the most useful, yet unu sual, table saw techniques is cove cutting. A strip of wood is clamped to the table at an angle to the blade to act as a fence. Then the stock is repeatedly passed over the top of the blade. For each successive pass, the blade is raised slightly, resulting in a deep cove throughout the length of the stock. Best of all, the shape and size of the cove can be varied tremendously with different fence angles and blade heights.

The fence fo r cut ting coves can be as s i m p l e as a stu rdy piece of flat stock fi rmly c l a m ped to the ta b l e of the table saw.
To visualize how this works, hold a circular sawblade at arm's length and pivot it slowly. As the viewing angle changes, the blade appears as a long, narrow ellipse. As you continue to pivot the blade the ellipse becomes broader until it appears as a full circle. Of course, you can't pivot the blade on the saw, so instead you attach an angled fence.

Fence angl e
The first step in using this technique is to mill a length of stock for use as a fence. The dimension of the stock isn't exact, but it must be of sufficient size to avoid flexing. A length of 2x4 works well once the edge has been trued on the jointer. Also, the stock must be longer than a standard fence to span the saw's table at various angles. An alterna tive to the single fence is a double fence through which the workpiece passes. Once you establish the angle, the fence must be securely clamped to the saw table using standard clamps or wooden handscrews. Finding the Ang le
Finding the correct angle may seem like somewhat of a mystery, but it's actually quite simple. In fact, there are a couple of meth ods from which you can choose. For the first method, you'll need to build the parallelogram jig shown at left. The jig pivots at the corners and locks in place to hold a setting. Set the space between the bars for the width of the cove and raise the

sawblade to a height that equals the depth of the cove. Next, place the jig over the saw blade and position it so that it contacts both the front and back of the blade. Now posi tion the fence at the same angle and clamp it in place on the front and back rails of the table saw. To find the angle using the second method, first mill the stock for the cove. Next, draw the cove on each end of the stock or simply mark layout lines to indicate the depth and width of the cove. Now raise the sawblade to equal the depth of the cove and position the fence so the blade enters the cove on one edge and exits on the oppo site edge. Finally, clamp the fence securely on the table. Making the Cut
It's essential for safety that you make the cove by taking multiple, light cuts. For the first cut, lower the blade to a height of 1/1 6 in. Then raise the blade approximately
1/1 6 in. for each successive pass. As you feed the stock over the blade, maintain contact with the fence and use push blocks to keep your hands a safe distance from the blade. On the final pass, the blade should contact the layout lines that mark the height and width of the cove. Afterward, you'll need to smooth the sur face and remove all traces of saw marks. A curved scraper makes this tedious process go much faster. Mter scraping, sand the surface lightly.

Carved Reverse-Stop Flutes Before carving stop fl utes, you ' l l need to mod ify the edge of the gouge. Carvi ng gouges a re somewhat square when you buy them . Although this profile is effective for most types of carving, the outside corners of the gouge will dig i n when incising a stop fl ute. I nstead, the end of the gouge m ust be semicircular to follow the con tour of the fl ute. The most efficient way to change the tool shape is to use a grinder. Roll the tool from side to side on the grinding wheel to grind away the corners. As you grind, keep the tool movi ng to avoid dead spots in the curve. After grinding, sharpen the tool to a m i rror surface with benchstones. A reverse-stop fl ute is a neat deta i l at the lower end of a fl ute (see the drawing on p. 2 1 3) . Rather than leave the fl ute end concave, as from the router, the end is ca rved to a convex profile. Like many details that add visual i nterest to a piece of furniture, reverse-stop fl utes ca n 't be created by machine. B ut for a special piece of furnitu re, the extra handwork is worth it. Beg i n by routing stop fl utes as s hown on p 2 1 5. Be certa i n to provide space for the carving. Next, lay out the stop fl ute. Use a combination square to extend the sides of the fl ute and a circle tem plate to draw the a rc (A, B) . Now select a carving gouge with a sweep that comes closest to the curve of the a rc. I ncise the curve by cutting vertica lly with the gouge
(e) .
Then carve parallel to the fl ute to complete the profile (D).

You can accom plish this by cutting to the dia meter at several locations with a parti ng tool. As you lever the tool i nto the spi n n i n g stock with one hand, gauge the dia meter with spring ca lipers in the other hand (F) . Then turn the rema i n i ng portion of the cylin

Special Techniques EYOND THE MANY WAYS TO CUT SHAPES
with familiar
tools, there are specialized methods for shaping wood. Turned shapes are familiar in chair and table legs, bedposts, and other rounded symmetrical forms. In fact, turnings are essential to some period furniture styles. Carvings have enhanced furni ture since time immemorial. One of the most artistic aspects of wood working, carvings not only provide interesting detail but allow the maker a highly personal form of creative expression. B oth turning and carving require a little more effort to learn, but the possibilities they offer the woodworker are well worth it. Finally, there's bending-the most distinc tive technique in the repertoire of shaping methods, because it is the one way to shape wood that doesn't involve cutting. Instead it takes advan tage of wood's natural flexibility and ability to be plasticized.

turn ing is cutting the wood while it spins on a lathe. The final shape is always equidistant from the center. This enables symmetry while producing an amaz ing variety of curved shapes. Try to imagine what furniture might look like if the lathe hadn't been invented. The beads, coves, and urns of the Jacobean table leg may not be to everyone's taste, but think how different the history of furniture design might be without turnings. Eighteenth-century furniture, which many consider a high point of furniture design, would look incomplete! Even a simple Shaker piece comes alive with the softer lines of a turned leg. Complex turnings are nothing more than combinations or modifications of simple shapes. A vase or urn shape starts out as a bead on one side and is cut like a tapered cove on the other. So even though turning may look challenging, once you learn to turn EDUCED TO BARE E S S ENTIALS,

ground. A tool with multiple facets will have a convex bevel. What's the difference? The bevel must continually rub the stock to sup port the edge while turning. A faceted, con vex bevel won't accomplish this. Keep your tools sharp. You'll gain more control and experience fewer "catches" with a very sharp tool than with one that's only somewhat sharp. This is a universal principle that applies to all edge tools, from a bench chisel to a kitchen paring knife. Turning tools dull rather quickly because of the friction gener ated heat. Although high-speed steel (HSS) tools are more heat resistant than those of ordinary carbon steel, they still require fre quent touching up with a slipstone. Learning to Use the Basic Tools

Some turning tools are friendlier than others, and the spindle gouge is easily the beginning turner's best friend. You'll achieve success faster and most likely enjoy turning more if you begin by mastering the spindle gouge. Learn to sharpen it correctly and practice making the basic spindle shapes using this tool. Once you master the use of the spindle gouge, you'll have a foundation for the movements needed to use the other tools, including the notorious skew chisel. This tool is by far one of the most useful tools, but it's easier to catch the work. Once again, patience and practice will reward you. Remember always to cut "downhill." To avoid a catch, it's crucial to cut from large diameters toward smaller ones. Woodturners call this cutting downhill.
Avoiding Chatter
Chatter is a woodworking term for "vibra tion." When turning, chatter creates a dis tinctive spiral pattern on the work, which can be difficult to remove. Chatter most often occurs when turning long, slender work. But even a heavy bedpost can some times be a problem because of its extended length. Fortunately, there are several solu tions to the problem:
•• • •• •

POSITIONING THE GOUGE Gouge
Adjusting the speed up or down slightly will often help put a stop to excessive vibration. Change the speed.
Turn the center of a long turning first.
Save the end portions for last to help reduce the occurrence of chatter. This will avoid weakening the turning, which causes it to flex and vibrate.

Special Cases
How do you turn something longer than the bed of your lathe? Divide it into two or more sections. This is an effective method for long, slender bedposts as well as shorter
turnings with small diameters. The finial shown on p. 242 is a good example. The narrow cove at the base of the flame makes this difficult to create as a one-piece turning. But by dividing it into two sections, the job's a snap. It also makes it easier to maneuver the gouges when carving the flame. As an

added benefit, this method allows you to turn long posts on a short lathe. When dividing a turning into sections, use a round mortise-and-tenon to join the sections afterward. Remember to plan ahead and position the joint adjacent to a bead where it will pass undetected. Turning Multiples
Turning several pieces alike isn't nearly as difficult as it may seem if you do some plan ning ahead. The first thing you should do is design your turning and make a master. When you're turning its mates, you can position the master behind your lathe where you can view it while turning. It's much eas ier to duplicate something within view. Use the master to create a story stick, which will allow you to lay out linear dimen sions of a turning quickly and accurately. To make a story stick, glue a photocopy of your drawing onto 1/4-in. plywood. Next, extend perpendicular lines from the plywood edge to the inside corner of each fillet. Finally, cut small V's along the edge of the stick as a rest for a pencil. To use the story stick, place it on the tool rest against the spinning cylinder. Then mark the cylinder by placing a pencil in each notch or This method is much more

One way to dramatically increase your accuracy and efficiency when turning multi pIes is to use individual calipers for each diameter. This way you'll save time and avoid the inevitable errors associated with continually resetting a single caliper. You can find serviceable calipers of many sizes at flea markets and used-tool dealers.
Tu r n i n g a Cyl i nder Tu rning a cyl inder involves removing t h e four corners of the stock to produ ce a smooth, u n i form s u rface. It's typically the fi rst step in pro ducing a spindle turning, such as a leg or post. Beca use the stock contacts the tool only four times per revolution, the i n itial stage of this process is natura lly rou g h . The best tool for the job is a massive, square-end gouge aptly ca lled a roughing gouge. Begin by securely mounting the work i n the lathe. To beg in the cut, sta rt with the gouge handle low and gradually l ift the handle u ntil the cutting begins (A) . Once the chips begin to fly, slide the gouge along the tool rest to s ha pe the entire length of the stock (8). To keep the stock un iform in dia meter, l i m it the cutting depth by bracing your fist agai nst the tool rest. TI P
When rounding square stock to
form a cylinder, you can qu ickly and easily check for roundness by holding the mid dle of the gouge on the spinning stock. If it bounces lig htly there's stil l a flat spot remaining.
To shape the stock next to a pom mel, rotate the gouge (C) and cut with the corner

As you
approach a true cyl inder, you can check the stock for rou nd ness by placing the middle portion of the tool on top of the spinning work
This
speeds the process by avoiding switching the lathe off and on aga i n . The finis hed cyl inder should be un iform and s mooth, and its dia meter should match the major diameter of the object you plan to turn.

'*, Tu r n i n g a Po m mel A pommel is t h e square corner o n a post or leg where a turned section intersects a square sec tion. It's created by shearing a V i nto the square stock with a skew. Beg i n by squaring the stock and m i l ling it to size. Next, locate the center at each end of the stock by d rawi ng diagonal lines. Mark the center with an awl to ensure accu racy. Then mount the work securely in the lathe. Before turning, mark a layout l i ne to ind icate the location of the pommel. With the stock spinning relatively fast, nick the corners of the stock with the point of a skew. Next, make the cut deeper and wider by working the skew from the left and from the right (A) . Each time you make a cut, lever the edge of the skew i nto the work (8). Use only the point of the skew to avoid catching the work and spoiling it. The pommel is complete when the cuts at each corner meet to surround the ci rcumference of the work (C) .

Bead Tu rned with a Spindle Gouge A bead i s a convex curve made u p of one-quarter or one-half of a circle or ellipse. Begin by establishing the size of the bead. Fi rst cut the fil lets that fla n k the bead (A). Then cut the bead to the req uired dia mete r. The next step is to s hape the bead. Always work from the center toward the edges, or down h i l l . Fi rst, position t h e gouge s o that t h e bevel rubs the spinning stock and then l ift the handle until cutting begins. N ow, rol l the gouge to form one half of the bead (8) As you roll the gouge, lift the handle and pivot the handle in the di rection you a re cutting (C) . The th ree movements-roll, l ift, and pivot-m ust be done s i m u lta neously. It takes a bit of practice, but you ' l l soon begin to deve lop a feel for it. As you roll the bead, watch the top of the work so that you can view the bead as it is shaped. After you 've shaped half of the bead, start at the

If the gouge catches d u ring the process, you 've most l i kely pivoted the handle too far, l ifting the bevel from the work. The resu lt is that the u nsup ported edge digs in, an occu rrence referred to as a
catch
by woodturners. If the cutting action
stops before you 've shaped the bead entirely, it's beca use you didn't pivot the handle far enough and consequently the edge is not making contact with the stock.

There a re some remedies for red ucing the risk of a catc h . Fi rst, keep the skew sharp. Sharp tools will a lways give you better contro l . Second, as you grind the skew, use a grinding method that keeps the bevel flat or hol low grou n d . A faceted, convex bevel will leave the edge unsu pported, which will l i kely result in a catch . To begin shaping a bead with a skew, first i ncise the width of the bead with the poi nt (A) . Next, cut V's at the i ncisions to remove the excess stock (8). Now, you ' re ready to shape the bead. Using the heel of the skew, start off-center of the bead to take a light cut (C) . Let the bevel rub, and l ift the handle until the cutting begins. Then rol l the skew, l ift the handle, a n d pivot it. After the fi rst light cut, start at the apex of the bead and repeat the process

For the leg to have the correct a ppearance the axes should converge at the pommel (A) . Begin by locating the true center of the stock on each end of the workpiece; then locate the cen ter for the an kle (B) . Next, mount the leg in the lathe with the foot at the ta i l stock. This wi l l avoid the risk of striking the drive center as you turn the foot. Now, turn the pommel with the point of a skew. Fi rst nick the corner (C) ; then cut from the left

Don't turn the foot yet; otherwise you wi l l cut away the center needed for turning the a n kle. The next step is to offset the stock i n the lathe (I). Most of the offset occurs at the foot end of
the stock. However, it's im portant to s l ightly off set the opposite end as we l l . Check the offset for accuracy before turning. When offset correctly, the two separate axes will converge at the pom mel. Tu rn on the lathe and watch the spinning " g host " of the leg to see where the axes con verge. If necessary, stop the lathe and reposition the leg at the top slig htly. Don't adj u st the center location at the foot-otherwise you ' l l change the dia meter of the a n kle. (Text continues on

the base of the ogee. Shaping the bead requi res a delicate touch with the heel of a small skew. You can gauge the width of this bead with a small set of dividers. The last profile is the small cove. Use a small spindle gouge and a light touch as you s hape each side of the cove toward the bottom

The bedpost design in this example i s from the ni neteenth century. It's a challenging post to turn
---1�� �II------�
becau se it has severa l shapes that req u i re use of
a skew (A) . To gain the most control of the skew and avoid catching the stock, keep it sharp. I n
fact, it's a good idea t o stop periodica l ly and hone the edges of the s kew with a very fine slip stone. Also, for each cut that req u i res a skew, use the largest skew in your a rsena l . The wide edge and extra mass of a la rge skew will add to your control of the tool on a large turning such as this bedpost. In addition to the square section of the post, which accom modates the ra il joinery, this post a lso has a decorative octagonal section between the turnings. The octagon is cut on the table saw before turning. After cutting the octagon, carefully locate the cen ters of the stock and mount the stock securely in the lathe. Next, mark the separate sections of turnings, square, and octagon . Tu rn the center of the post first. Beginning with the center turning, score the corners at each end of the turned section to create the pommels. Then turn the square ( 8) and octagon pommels (C) with the point of a la rge skew. Use care at
the octagon ; it's easy to cut too deep. N ext, turn the stock round with a roughing gouge ( D ) . Use the corner of the gouge to turn carefully next to the pommels

Hold the skew at an angle corresponding to the angle of the V, and lever the tool 's edge into the work (H) Next, use the skew to cut the half of the bead adjacent to the V ( I ) . Before shaping t h e second half o f t h e bead, remove the excess stock adjacent to the bead to provide room to maneuver the tool (J) You can a lso complete the other half of the bead with a skew or, if you prefer, use a spindle gouge, which is less l i kely to catch

Finally, turn the large
bead (L) and complete this section by turning the cove (M). Because of its long length, even a massive turning such as this bedpost may vibrate . This is especially true when turning i n the center, f a r from the su pport o f the headstock and tai l stock.

ARVED ELEM ENTS HAVE B E EN U S E D
since the beginning of time as fur niture embellishment. Despite the seeming complexity of the carvings, anyone with hand-tool skills can learn to carve sim ple shells, fans, and rosettes-all of which can add interest to a piece of furniture. Why add carving to your repertoire of woodworking skills? Obviously, if your goal is making reproduction furniture of certain periods, especially the eighteenth century, you know that carvings are an essential ele ment in many pieces. But there's another reason. Carving allows you a way to express yourself as few other aspects of woodwork ing. Even if you're attempting to reproduce a historical carving, yours will never be exactly the same as the original. A carving is made one patient cut at a time. And each cut is made by the individual maker's hand. Why not yours? Designing Carvings
Successful carving begins with a good design. You don't have to be an artist to design carvings. Beautifully designed carv ings have been used to decorate furniture for centuries. Get some good books that show carved details and study them for inspiration. Remember that it's important to blend the carving with the furniture design on which it will be used. An ornate eighteenth-century motif will look out of place on a modern piece. Proportion is also essential. If the carved ornament is disproportionate with the scale of the overall piece, it will distract rather than add to the piece.
Once you've chosen the motif you want to carve and determined its proportions, the next step is to create a drawing. It's difficult to overemphasize the importance of the drawing; it provides an essential road map for carving. Create the drawing full size and add the details. This means not simply the outlines of the carving and its highest points. Because carving is three-dimensional, you'll need to consider the play of light on the parts. Indicate the highs and lows with shading. Once you're satisfied with your sketch, transfer it to your workpiece to use as a guide when you begin to cut.
This c h a i r back featu res a ca rved s h e l l and ca rved vol utes.
Secure the Work
If the carved surface is not secure you run the risk of two things: ruining your carving or, worse, cutting yourself. The way you secure your carving is determined by the work itself. Directly carved work may be secured by clamping the part on which it is carved. However, many carvings are glued or
C a rv i n g
1 25 3
fastened to a backup board. Feet, such as the trifid and ball and claw, can be secured in a pipe clamp. Sometimes, as in the case of the flame finial, it's necessary to devise a special jig to clamp the work without damaging it. Applied carvings, such as the shell, can be glued to a backup board for carving. Make sure to clamp the backup board to a sturdy surface such as a workbench. Keep the Tools Sharp
Your best work begins with sharp tools. There's nothing more frustrating than hav ing a gouge slip because it's not sharp enough to bite into the wood. Invest in a set of good slipstones for honing the many shapes of carving tools. A small number of Use cla m ps m o u nted i n a vise to hold complex s h a ped ca rvi ngs.
An assortment of s l i psto nes i n various sha pes is usefu l fo r kee ping your ca rvi ng tools sha rp.
254 I
C a rv i n g
tapered slipstones can service many shapes. Keep a leather strop nearby for quick touch up, and hone the tools often, especially when carving fine details. Go with the Grain
Always cut with the grain or across it, never against it. When you cut against the grain, you risk splintering and tearing out the wood instead of cutting it. Sometimes it's hard to determine the grain direction, especially in multilayered, complex carvings. Try taking a light cut. If the tool is digging in instead of cutting cleanly, turn around. Cutting across the grain is a good method for initial shaping and quickly removing excess stock. When possible, the final surface should be created by cutting with the grain. Use the Tools to Your Advantage
Gouges come in various widths and sweeps (curvature) to create the curves . Although many carvings can be accomplished with a dozen or so tools, it's necessary to have a good assortment. Don't cramp your style by attempting to carve complex designs with two or three gouges. On the other hand don't go out a buy a set of tools just to have a selection. Start with a few basic shapes and learn to use each well. You can always add individual carving tools for a given project. Before you begin to cut, study the project to determine which tools you'll need to accom plish the carving.

Keep the Details Crisp
The best carvings show the clean definition achieved by cutting the wood rather than abrading it. A rasp may help remove large amounts of material, but when you come to the final surface, pick up your carving tools. Avoid excessive sanding. Use light sanding
to smooth the carving, not shape it. Coarse abrasive and excessive sanding only spoil the crisp edges and details that you worked so hard to create. And don't try to remove all of the tool marks; they're the true sign of hand carved work.

When incising the outl ine of the shell, it's impor tant to keep the cuts vertica l . To achieve this, you ' l l need to angle the gouge away from the work for the concave cuts.

you ' re ready to move on. The next step
is to glue it face down to a short length of inex pensive stock. Afterward, the clamps are posi tioned on the scrap stock to give you full access to the shell for carving. Don't use a lot of glue; the shell m u st be pried up after carving. Besides, a small amount of g l ue is all that's necessary to hold it firmly (K) . Clamp the shell to the board and al low the g l ue to thoroughly dry (L) The next stage of the process is to contour the face of the shell. But first mark the high poi nt of the contour. The point is centered left to right and s l ightly below center from top to bottom (M) Now select a 25mm no. 2 gouge for shaping the contour.

Ca rvi n g a Vol ute A volute is a spira l (A) . It's used as embellis h ment on the ends of arms and the back of chai rs-among other a reas-to create the a ppearance of a scroll. As the volute unwinds, the curve natura l ly broadens. This bea utiful effect is easily created by using a series of gouges. Begin by drawing the volute. Although it would
II
be easy if the volute fit with i n a mathematical framework, it seldom does. I n stead, the vol ute must fit with i n the a rea of the workpiece on which it will be carved . For this exa mple, I 've connected vol utes of two sizes to create a sample carving block. Whether found on furniture or arch itecture, vol utes a re typically carved in pairs. As you might imagine, d rawing accu rate pa irs of vol utes can be time consuming. So for ease of d u p l ication, I prefer to make a plastic template. Fi rst d raw the design on paper; then position a transparent plas tic sheet over the drawing and incise the outline to form a template (8) Next, trace the template onto the stock (C) and begin carving
((0E)).
Begi n n i ng with the center h u b, i ncise the outline of the volute with the same series of gouges that you used to incise the template
As the
curves become broader, use wider gouges with less sweep (F) . A typical se ries of cuts would begin with a no.

progress to a no. 5, and
end with a no. 3 gouge. I ncise the volute to a depth of

Next, make a second series o f cuts that i ntersect the first cut at a shal low angle (G). Each time you make a cut, a small chip of wood should be released. This will have the effect of creating a ra ised spira l ridge ( H ) . After this procedure is fol lowed a round the entire spira l , a series of facets will rema i n .

nine ridges. Before sketching the rest of the ridges, put the turning back i n the lathe and divide the height of the flame i nto th irds. Next, draw a line a round the circu mference at the poi nt of each division (E) Now you ' re ready to divide the turning I nto
sepa rate ridges-nine a round the middle and six at the top and the base. Beg i n n ing with the base, position one leg of the dividers on the fi rst ridge and step off six spaces (F) . Next, step off six spaces at the top sta rting
with the ridge you 've a l ready d rawn . Finally, divide the turning i nto nine equal spaces at each of the circumference l i nes, sta rting each time at the ridge (G). Now you ' re ready to sketch in the rest of the ridges. Starting to the right of the first ridge, sketch in the adjacent ridge. It begins at the base and flows upward, ending before it reaches the top. Use the division poi nts as g u ideli nes, but remem ber that they a re there as only a guide; it's not necessary to fol low them precisely. It's most important to draw a smooth, flowi ng curve (H). The third ridge sta rts at the top and ends before reaching the base. Then the pattern is repeated twice more. When the layout is complete, you should have a total of n i n e ridges, yet only six points at the top and six at the base. Before ca rv ing, study your layout and check for spacing and
264
C a rv i n g
i rregula rities in the c u rves. The layout does n't req u i re mechanical precision, but instead the li nes should flow gracefully as they spira l toward the top. Spacing s hould look somewhat u n iform ; but it doesn 't need to be, or should be, perfect. The idea is to create a carving that is well propor tioned with pleasing c u rves. Before you beg i n carving, take a few m i n utes to build the jig shown in photo I (at right) and photo M (on p. 266) . It's essentia l ly a V block with a build-i n clamp for securi ng the work.

A sectional view of the carving reveals a series of ridges and V's. Each of the cyma curves that you sketched earlier becomes a ridge; the a rea between a pa ir of ridges forms a V. Carving is now simply a matter of removing the a rea between the ridges. And if you keep a couple of key poi nts in m i nd as you carve, success is virtu ally ensured. First, keep the tools s ha rp; sha rp ness is critical to control of the tool . I keep a leather strop on my bench and hone the edges periodically. Second, always carve with or across the gra i n , not agai nst it. If you attempt to work agai nst the gra i n the wood will splinter and tear. Beg i n by carving across the g rain toward the bot tom of each V (I) Alternate the cuts from either side of the V so that the wood between the cuts is removed clea nly (J). Work from the center of the V outward toward the ridges and from the base of the flame to the tip. Cutting across the grain will leave the surface slightly coa rse; but the technique removes wood q u ickly, and you ' l l smooth and refine the s u rface later b y carving with the g ra i n . As you carve, remember that each layout l i n e becomes a ridge. Also, it's i m porta nt that t h e l i n e formed by t h e bottom o f the V is smooth a n d flows i n harmony with t h e ridges. A s you deepen each V adjust the li ne, if necessary, to cause it to flow smoothly. (Text continues on

Avoid carving too deep a t first. Once you 've carved the entire ci rcumference of the turning you ' l l have a better feel for the look you ' re trying to ach ieve, and you can deepen the cuts, if nec essa ry. U n l i ke many other a reas of woodworki ng, carving isn't a process of cutting to a set of pre cise di mensions. I nstead, it's a matter of creati ng balanced, flowing l i nes. Often the l i nes can't be gauged or measured but are j udged by a critical eye. In this case, each l i ne should spira l along its length in a flowi ng, u n i nterru pted cyma curve. As the carving progresses, the only remaining portion of the original tu rned surface will be each ridge. Be careful to leave the ridges i ntact otherwise the flow of the curve that you created on the lathe wi l l be spoiled. The only exception is the ridges that stop before reaching the base or the tip. Ca rve these ridges downward at the ends so that their l i nes flow smooth ly toward the center of the work
(K) .
When you ' re satisfied with the i n itial carving, the next step is to refine the work. With a 1 2m m no. 2 gouge, s mooth t h e surface o f each curve by cutting with the gra i n (L) . Sever the end g ra i n a t t h e base between t h e fla mes with t h e point of a skew. The final touch is to carve the tiny veins on the s u rfaces of the fla me. These shal low grooves break up the otherwise flat surface to give the carving g reater detai l and visual i nterest. But fi rst sketch them in with a penci l . Depend ing o n the width of the surface, each has th ree to five vei ns. Using you r middle finger as a gauge, d raw each vein beginning with the ones at the outer edges (M). The veins toward the inside may not flow entirely from top to bottom but may fade out as the surface na rrows. Then with a steady hand, carve each vein with a 1 . 5 m m no. 1 1 gouge ( N ) .

Next, make a pattern for the bottom of the foot to serve as a g u ide while carvi ng. Heavy card board works well for the pattern; simply incise the outline with gouges that match the curves. Then position the pattern on the base of the foot and trace the outl ine (A). To beg in carvi ng, secure the leg i n a pipe clamp that is mou nted in a vise. For consistency, use the same gouges for carving that you used for incising the pattern. Carve the profile of the toes starting at the top of the foot and worki ng toward the base (8) . As you carve, maintain the angles on the edge of the foot that were established earlier when bandsawi ng. I nvert the gouge to carve the convex a rea (C, D).

To outline the concave areas that form the stock ing, flex a stra ig htedge i nto the curve and trace it from toe to a n kle ( G ) . Now you ' re ready for the next stage of carvi ng. Begi n n i ng at the toe, scoop out the wood be tween the toes with a no. 5 gouge (H). As you near the sharp curve at the ankle the gouge will have a natu ra l tendency to dig i n ( I ) .

ENDING I S O N E OF T H O S E TECH
that seems exotic but is really simple. Bending opens many design options to the furniture maker, especially when a large curve is required and cutting the wood will leave too much short grain, weakening the curved part. This section cov ers bending techniques that can be applied to making furniture. The furniture maker has basically two practical strategies for bending wood: lami nating and plasticizing the wood using heat. The most practical heat method is steam bending, which is widely used in boatbuild ing and other types of woodworking where long bends are required. A specialized N I QU E S
This rocki n g c h a i r conta i n s several stea m-bent pa rts.
method called hot pipe bending also employs heat but is limited to bending very thin parts for musical instruments. Another specialized method, called kerf bending, has some utility in making mirror and picture frames as well as in high-end architectural woodwork, where it is sometimes used to bend trim. Because the kerfs are visible in the finished work, this method has obvious shortcomings. Bent Lamination
Laminated bends are made by bending thin layers of glue-coated stock around a curved form. The layers are held in position with clamps or a vacuum press until the glue sets.
The stea m-bent rungs of this chair back p rovide n ot o n ly a n i nteresting design e l e m e nt but a l so comfo rt. Bending

laminae,
Afterward, the excess glue i s scraped and removed and the edges are trimmed flu sh. Bent laminations are very strong, and the method is extremely versatile. Narrow lami nations are used for legs of tables and chairs; wide laminations are used as the sides for casework. Laminations are also widely used in architectural woodwork from beams in churches to stringers in circular and geo metric stairs. The only downside to bent laminations are the layers themselves, which can some times be distracting. To overcome this prob lem, it's helpful to mill the lamina from one piece of stock, keeping track of the layers and gluing them together in the original order. Still, some of the stock is lost in the kerf during milling, so the grain in the lami nation won't be a perfect match. Tapers should be cut before laminating. Otherwise the taper will cut through the individual layers, adding to the visual distraction. Steam Bending
Steam bending is a process of softening the wood fibers with a combination of heat and moisture until they are sufficiently pliable to bend. The hot, wet sticks are pulled from a steam box and quickly wrapped around a
274
I
Bending
curved form. Depending on the size of the stock, pressure for the bend can be supplied by physical force or supplemented with clamps. After the bend, the part is held in position until it has cooled and sufficiently dried to maintain its new shape. Wood that is steam bent undergoes extreme stress. The cell structure on the convex side of the bend is stretched while that on the concave side is simultaneously compressed. The fact that wood can be bent this way is remarkable in itself Although steam-bent parts lack the strength of bent laminations, they are still remarkably strong. And they are obviously much stronger than bandsawn stock, which has been weakened by short grain. Also, steam-bent stock lacks the dis tracting layer lines present in laminations. Instead, the grain runs naturally and con tinually throughout the curves of the stock. Steam-bent stock can be carved, too; whereas the glue and constant grain changes of bent laminations make carving impractical. Bending Forms
Bending forms should be stiff and strong to resist the forces of bending. Most important, the curve of the form should be smooth and consistent. The best material for forms is plywood. Solid wood tends to have weak areas resulting from short grain; particle board is harsh and quickly dulls tools. However, plywood doesn't have these short comings. It's easily worked and doesn't move drastically with humidity changes. To create a thick form, stack the plywood in layers and use glue and screws to fasten the layers together. Make certain that the
screws are located away from the path of the eventual curve. Steam-bending forms require a system for holding the parts in position until they have cooled and dried sufficiently to retain their new shape. This can be a simple arrange ment of pins and wedges or a more complex system of steel rods and bolts driven with a pneumatic impact wrench. The decision often rests on the thickness of the stock and the severity of the bend. Bent lamination forms to be used in a vacuum bag require softening along edges and corners. Otherwise, a sharp corner may puncture the bag.

Kerf Bending
Kerf bending involves sawing a series of deep kerfs across the grain to weaken the stock. After kerfing, the thin upper layer that remains is flexible, which allows a bend to be made. After bending, the stock is quite fragile and must be supported. As you have probably concluded, kerf bending is impractical. The kerfs are quite distracting; and, even if hidden, they tele graph through the face of the bend. Also, the stock is severely weakened and has absolutely no structural integrity unless the kerfs are later filled with wood or epoxy. Even so, this simply adds to the visual distraction. If you need to create a wide curved panel without the time and fuss of laminations and the inherent weaknesses of kerf bending, a better solution is bendable plywood.

Steam Ben d i n g To find the examples g iven i n this section on steam bending, I visited Brian Boggs at his shop i n Berea, Kentucky. A long-time chairma ker, Brian has taken steam bending to a science. H e uses a pressure cooker to s u pply the stea m , a n d his steam box is sta in l ess steel . The steel steam box is fitted with i n a well-insu lated wooden box. His forms a re soph isticated, too. B u i lt up of layers of plywood, the forms have stain less-steel straps that fit over the outer portion of the bend to prevent fa il ure from the extreme stresses that occu r when bend ing. Begin by selecti ng the stock and working it to rough size . It's im portant that the gra i n is stra ight and runs i n the same direction as the stock. The stock can be rived (spl it) or sawn, as long as the grain direction is parallel with the edge and face (A) . After roug h sizing, m i l l the stock to fina l size.
The next step is to steam the parts . A rule of thumb is to steam the pa rts 1 hour for each inch of thickness. Make certain that the steam box is hot before loading the parts (8) Ta ke advantage of the time while the parts a re stea ming to make preparations for bending. Make certa in your form is i n place and that you have the necessary clamps at hand. Once the pa rts a re sufficiently pliable to bend a round the form, remove them from the steam box.

(0).
The next step is to s hape the profile. There a re a couple of keys to shaping such a small piece: add mass to reduce chatter and provide a method to grasp the part safely for shaping. One sol ution is to g rip the part within the jaws of a wooden handscrew. The heavy wooden clamp effectively adds mass and positions hands a safe distance from the spinning router bit. Also, if the bit i nad vertently contacts the jaws of the clamp, there's no dangerous meta l-to-meta l contact.

Begin by shaping the ends. Tighten the jaws of the clamp firmly around the stock. Next, feed the work into the spinning bit until the plywood tem plate ma kes contact with the bearing

This way pressure is applied to the stock as it is shaped, preventing chatter. After making the jig, m i l l the stock for a snug fit with i n the g roove of the jig ( 8 ) .

The pa rts being shaped i n this example are the base and capital for a pilaster, or flat col u m n . After shaping, the complete pilaste r is added to the i nterior of a desk.
�
See "Fluted Quarter Columns "
on p . 217.
The fi rst stage in this process involves shaping a strip of moldi ng. After shaping, short blocks of the molding a re cut from the strip for use as the base and capital (A). B ut fi rst the ends of the blocks m ust be shaped, or " returned , " with the same profi les used on the face of the block. This setu p al lows safe and accurate shaping of very small workpieces such as these. For each profile, orient the stock on the edge (8) or end (C) and firmly clamp it to the backup board on the miter gauge.
