Armchairs can be built with well-seasoned lodgepole or eastern pine, or
birch (fig. 38). The cornerpieces should be mortised and tenoned to the
frame and rail and anchored in place with 3/8- by 15-inch lag screws. The
arms should be fastened to the cornerpieces with 3/8- by 5-inch carriage
bolts and to the slab support with 3/8- by 4-inch lag screws. The
vertical slab support should be rigidly secured to the frame with 3/8-
by 3-inch carriage bolts. Cushions may be of the filler type, without
springs, and covered with homespun fabric. Use 2-inch wide heavy canvas
strips, securely fastened with furniture tacks, to support the cushions.
Upright chairs and stools (fig. 39) can be made from the same material as
the armchair. Cross the poles to impale the legs rigidly. The crosspieces
of the chair back should be curved to fit the human back. The joints must
be tightly glued, mortised, and tenoned.
