For the support shown in Fig. B, Plate 2, we make the upright 7/8" × 6-3/4" × 8-7/8". The top is cut 7/8" × 6-3/4" × 12" and the base 7/8" × 5" × 6-3/4" and the upright brace 7/8" × 3" × 8". The top has the same V-shaped notch cut in it as the other form of support. Bore all necessary holes, sandpaper and assemble. The clamp shown in the sketch answers the purpose very nicely and may be purchased for a small sum at any hardware store.
