This demonstration table is designed to show that no matter the style, a table with a single drawer has the same interior components. The aprons, kickers, doublers, and runners all combine to guide the drawer in and out of the drawer opening (called the pocket).
1. Doublers are glued to the inside face of the side apron.
2. Square-dimensioned runners and kickers are glued and nailed to the doublers.
3. The runners and kickers house the drawer while the doublers guide the drawer side in and out of its opening.
I like to tell my woodworking students that there’s a Shaker nightstand hidden in every table with drawers. I may be overstating my case, but only by a bit. At North Bennet Street School, we teach strategy. Our largely traditional approach to building tables with drawers isn’t the only approach, but it’s almost endlessly adaptable; once you understand it, you can apply it to Chippendale writing desks,
Pembroke tables, contemporary tables, whatever you like. A single, sound approach is liberating: It leaves room for good design and good workmanship while eliminating the need for mock-ups, prototypes, and reinventing the wheel.
There’s nothing new about this attitude. Thomas Chippendale’s Chippendale Director contains page after page of chairs and chair backs. No joints. No dimensions. Nothing about how to build a Chippendale chair. Chippendale assumes his readers know how to build a chair and that chairs are all built the same way.
When our students build a table with drawers, they learn a system. I recall a student who started a veneered Pembroke table after having made a simpler table. “Remember when you built the Shaker nightstand?” I said to him. “Now here’s what you’re gonna do different.” His eyes lit up and he said, “Ah, and you just make this longer, and curve that and, oh, yeah, yeah, yeah.” He knew how to build a Pembroke table – he just didn’t realize it.
The single-drawer demonstration table I built (above and facing page) reveals the basic components of a simple table-with-drawer system: dividers, which replace the front apron to make room for the drawer; doublers, which fill out the side aprons and serve as drawer guides; runners, which support the weight of the drawer; and kickers, which keep the drawer from tipping when pulled out. Some tables require ledgers to support the runners and kickers, and there are others that do without doublers. Nevertheless, if you took apart a Pembroke table, you’d find the basic components in one fashion or another. And you’d know the secret to building tables with drawers: Inside, they’re all about the same.
A long table with multiple drawers has the same basic components as a narrower table with a single drawer, but partitions are added between drawers. For illustrative purposes, this table shows two types of partitions.
It’s worth taking a close look at the components that make up the table-with-drawer system, not only in terms of how each functions as part of an overall design but also in terms of how each is constructed in concert with the other components.
Although there’s no reason why you couldn’t apply my strategy to building a table by hand, I’m going to assume you will use a tablesaw and a thickness planer. For me, efficiency demands the use of machines, even for the construction of traditional furniture forms.
The key to efficient construction lies in designing joints that share like dimensions and like locations relative to the leg. The tablesaw cuts related parts to equal length; the planer establishes consistent thicknesses and widths. Together, the tablesaw and thickness planer allow groups of parts to have compatible machine-cut joints.
When you plane the dividers to thickness, you also can plane a number of square-dimensioned sticks for runners, kickers, and ledgers. If you make the haunched tenons on the aprons and the double tenons on the lower divider the same length and location from the face of the leg, then you can cut all the mortises on a hollow-chisel mortiser with a single fence setting. And you can cut the main shoulders of these joints, as well as the dovetails on the upper divider, without changing the dado height or the fence setting.
Once you’ve milled the pieces, you’re ready to put together the essential table: four legs, three aprons, and two dividers. The upper divider is dovetailed into the leg; the lower divider can’t be dovetailed, so it’s double tenoned (see drawing, above). With the table glued up, you can take your time installing the inner pieces – doublers, kickers, runners, and (if need be) ledgers.
The first pieces to go inside I call doublers because, roughly speaking, they double the thickness of the aprons. More important, the doublers bring the apron assembly flush to the inside face of the leg, so you don’t have to notch the runners and kickers. Some people would call the doublers side guides, and that’s what they are as far as the drawer is concerned: blocks that keep the drawer from shifting from side to side as it’s pulled out. Cut four doublers to length, and glue them to the top and bottom of the side aprons.
Onto the surface of each doubler, glue one of the little square sticks you thickness planed at the same time as the dividers, one at the top of each upper doubler to serve as a kicker, and one at the bottom of each lower doubler to serve as a runner. Together, a doubler and runner/kicker form an L-shaped piece, which you could make by rabbeting one piece. But they’re much easier to make and install as two pieces. The wide face of the doublers remains stable when glued flush against the apron. The kickers and runners are such small squares that they won’t curl or twist.
On a small table like my single-drawer demonstration table, gluing the runners and kickers to the doublers, and letting them butt against the dividers and the rear apron (or a ledger for securing the tabletop), provides enough strength to support the drawer. On a larger or heftier table or one with multiple drawers, you may need to join the runners and kickers at the front and back. At the front, you can tenon the runners to the lower divider and the kickers to the upper divider. You may not want to tenon the runners and kickers at the back, however, because you’d have to glue up all the pieces at once. Imagine doing that on a lowboy with five offset drawers.
To avoid having to glue up all those pieces at once, dado the top and bottom ledgers (which you have milled and ready) across their width to accept a half-lap joint from each runner and kicker, and then temporarily attach the ledgers to the rear apron using brads. To allow you to install the kickers and runners after the table frame is glued up, cut them a touch short. Cut the tenons relatively short as well. Even a 3⁄8-in. tenon will take the weight of a drawer. Just slide in the tenons, and snap the pieces into place. Then slide in the ledgers, using the brads to locate them for gluing.
If the span of the table is long and you need stronger dividers, there are only two things you can do: Make the dividers wider, or make them thicker. Making them thicker is, by far, the easiest route to take because a little thickness adds a lot of strength. But many designs simply won’t allow for a thick divider.
If you settle on making wide dividers, however, you’d better make them really wide. An extra 1⁄2 in. isn’t going to increase the stiffness of the divider to speak of, and an undersize divider will deflect downward. I’d make the divider 4 in. wide at least; a 4-in. divider is no more work than a narrower one. The trouble is, a wide divider stands a good chance of cupping or twisting. To resist racking, you have to join a wide divider not only to the legs but also to either the doublers or the side aprons.
When you join a divider to a side apron or doubler, however, you run the risk that the movement of the apron as it expands and contracts will work the divider like a lever. To prevent this movement from cracking the dividers (below), keep the aprons relatively narrow (ideally less than 4 in. wide), and make the dividers really wide so that movement at the inner dovetail is spread over a greater distance before it reaches the front dovetail.
Joining the dividers directly to the side aprons is historically accurate, but it’s tricky because you have to mill dividers longer than the rear apron and then notch the dividers around the leg. The other way to join wide dividers is to attach them to the doublers. A big advantage to attaching wide dividers to the doublers rather than to the aprons is that you can make both dividers the same length as the rear apron.
The dovetails are easy to cut because they share a shoulder, and all these shoulders can be cut with the same dado setup used for the apron tenons. The forward dovetail is joined to the leg exactly as it would be on a narrow divider. The inner dovetail can be either a full dovetail, as it is in my table, or a half-dovetail. In either case, leave as much space as possible between the inner dovetail and the end of the doubler. If the housing for the dovetail is close to the end of the doubler, the little short-grained piece that remains can easily crack off.
Joining the lower divider to the lower doubler is a little trickier. The lower divider, you remember, is double-tenoned into the leg, so you don’t want to dovetail it to the lower doubler because then assembly would be difficult. Instead, join the lower divider to the lower doubler with a horizontal tenon, cut to the same length as the twin tenons. This inner tenon must be as thick as possible for strength, with little or no shoulder on top, so there is enough wood in the doubler below the mortise to provide adequate strength; the doubler will still have plenty of wood above the mortise (see bottom left drawing, p. 45).
Whether you make the dividers wider or thicker, sizing them is a judgment call. Err on the side of overbuilt. If the table bounces, what are you going to do about it? If it’s a bit sturdier than it needs to be, you’ll never know, and you’ll be none the worse for it.
1. Dovetailed partition
A dovetailed partition is easier to install than a tenoned partition because it can be slipped into place after the dividers have been assembled.
2. Tenoned partition
The strongest way to tie together the dividers between the drawers is a vertical partition with through double tenons or triple tenons. (The plan view drawing below is shown at the lower divider.)
A table with multiple drawers requires a partition tying together the dividers between each drawer and a complement of internal runners, kickers, and drawer guides. It makes sense to mill the partitions at the same time as the dividers; just be sure to leave the divider blanks long, and whack the ends off. There are your partitions, already at the proper width.
If you feel comfortable with the span of the dividers and you simply want two drawers for looks or functionality, then you can stop-dado a nonstructural partition into the dividers from behind. But if the dividers are really long—for example, 3 ft. or 4 ft.—the stopped-dadoed partition may pop out when the table deflects downward.
The easiest way to strengthen the joint between the partition and the divider is to use the same double-tenon arrangement used to join the lower divider to the legs. On my multidrawer demonstration table, the dividers are so wide, I used triple tenons (see photo and drawing, left), but the idea is the same. I usually run the tenons through the dividers and sometimes even wedge them. If you join a pair of 3-ft. dividers together with two partitions and join the whole assembly to the legs, then you’ve created a girder. It’s amazing how stiff this system is.
So now that you have partitions between the dividers, how do you support the drawers in the middle of the table? You mill runners and kickers wide enough to support drawers on both sides of the partitions, tenon them to the dividers, and half-lap them to the ledger on the rear apron.
Treat these inner runners and kickers as you would the runners and kickers next to the doublers, with one big exception. You have to notch the middle of the tenons so they don’t interfere with the vertical twin tenons of the partition. To keep the draw-ers from swimming around, take another square stick, and glue it onto the center of the runner, long grain to long grain, to serve as a drawer-side guide. Problem solved.
You could also dovetail the partition to the dividers. A dovetailed housing cut across the full width of the dividers could remove so much material that it would compromise the strength of the dividers, so use a stopped dovetail in the front to tie the dividers together, plus a shallow 1⁄8-in. dado across the width of the dividers to keep the partition from twisting (see drawing, facing page).
Dovetailed partitions are easier to install than tenoned partitions because with dovetailed partitions, you can attach both dividers to the legs and then simply slip the partitions into place. The shallow dado allows you to slip the partition into the dividers and then scribe the tail onto the dividers before cutting its housing. It’s possible to cut the dado narrower than the dovetail to hide it from the front, but now I’m getting into variations on variations.
The beauty of this approach to engineering a table with drawers is that it doesn’t rely on the proportions or the style of the table. You can cut big legs or little legs; you can set the aprons flush to the legs or inset them; you can turn the legs or taper them; you can make the table long and low and turn it into a coffee table or tall and long and call it a writing desk.
What I hope I’ve constructed here is a conceptual framework onto which you can overlay your own design ideas.
