20 Leg Pads (4) 1" Dia. 20 Leg Pads (4) 1" Dia. Figure 1: Mortise and tenon joinery is the key to this chair's durability. Different mortise locations create right and left chair parts. Some of the tenons are mitered to meet inside the uprights. of the leg mortises. These mortise locations (see Figure 1) create right and left chair pieces. Now is the time to make the pyramid details on the top of the legs. See the sidebar on page 35 to learn the proper technique. The backrest of the chair is comprised of two rails (pieces 3 and 4) and five vertical slats (pieces 5 and 6). The rails are joined to the back legs with mortise and tenon joinery, just as the slats are joined to the rails. Cut these pieces to size. Form mortises and tenons as required, following the Pinup Shop Drawings. Building the First Subassembly With the backrest rails and slats milled, there's only one detail to address before you can complete your first, subassembly. Following the profile shown on the Pinup Shop Drawings, lay out the angular cut on the top edge of the backrest top rail, then trim it to shape on your band saw. Belt sand the saw marks until they are gone, then give the rails and slats a thorough sanding to 180 grit. Dry fit the slat tenons in the rail mortises and, when everything fits perfectly, glue and clamp them together (see Figure 2, page 36). Make sure the subassembly is perfectly flat and square when you tighten the clamps, then set the backrest aside to dry. The Four Arched Rails Perhaps the most challenging aspect of this chair is forming the side subassemblies. Each of these is composed of an arched top rail (pieces 7), a flat bottom rail (pieces 8) and five slats (pieces 9 and 10). After cutting these parts, along with the final two arched rails Mechanically: 1$ It Time To Make The Move? Depth adjustable \ I By pull handle Handle adjustment Drilling square holes is a snap with a mortising machine. Here's how it works: an auger-like drill bit is housed inside of a square hollow chisel. Available in many standard sizes — and able to form mortises in hard and soft wood — these machines are true time savers. Fence adjustment Hold-down Fence Mortise chisel A lever locks the fence on this model in place, A hex nut secures the U-shaped hold-down. The key advantage of a mortising machine over a mortise attachment on your drill press is the longer stroke of the machine, allowing for deeper one-step mortises.
