long in the back rail. Open mortises 1 in. deep are cut in the back posts to receive the ends of the arms, as Fig. 2.51. Maple armchair. INDOOR FURNITURE CONSTRUCTION shown in C. The back can now be assembled and clamped. The tenons are peg with Yain. dowels when dry. Double tenons 1 in. long are cut in the front rail ends, with corresponc mortises on the inside edges of the front legs, with the front rails flush with front surfaces of the legs. Provision is made for doweling the "ears," which cut to any desired curve. The front rail is then glued and clamped into the fr legs. While the front and rear assemblies are drying, the ends of the side rails cut into double tenons У in. long at the front and i in. long at the back. Th are inserted into corresponding mortises cut in the front and back assemblies ; the frame is glued together and clamped square. When the frame is dry, the arms can be inserted into their mortises in back posts and doweled to the top of the front legs. The supports are dowe at an angle parallel to the front edges of the rear posts as shown in A, Figure 2. For additional support, small triangular blocks of in. scrap can be glued to rear ends of the arm, against the back posts. Corner blocks are screwed' in place in below the top edges of the ra with cleats between, to hold the slip frame for the cushion. The latter is of simp lapjoint construction, 20 in. X 23 in. square, and rests on the corner blo< and cleats, flush with the top of the rails. Alternate layers of upholsterer's webbi are tacked to the frame, which is then covered with muslin. The fabrication the cushions is described in Chapter 7. Loveseat. The extension of the maple armchair into a small settee is eas accomplished by adding 22 in. to the length of the front and back rails, th doubling the seating capacity. For additional strength, a legless center post mortised into the back rails. A compact loveseat will result when both front and back rails are lengthen to 45 in. The slip frame, if lengthened, should have a center brace added; optional method is to use a frame for each cushion. The additional seat and back cushions are the same size as those of t armchair, Fio. 2.52. Sectional loveseat. H4 . Sectional Units. The vogue for "corner couches" was probably fostered by the desire to produce a conversational focal point so essential to the achievement of a successful living room. To provide for the maximum of architectural differences as well as for individual whims, sofas or couches are now available in three or more sections. The two outer sections have one arm each and the central section has none, thus making it possible to place them around a corner, with a corner table of the proper size to fill in the gap. As pictured in Figure 2.52, these sections can be easily constructed from the original maple armchair model. On the end sections, the inner arms are omitted and the inner front legs cut off level with the top of the front rail; the middle section is armless.
