Next provide a 4" × 4" piece (G), 40 inches long, through which bore a ¾-inch hole (8), 2 inches from the upper end, and four bolt holes at right angles to the shaft hole (8). Then, with a saw split down this bearing, as shown at 9, to a point 4 inches from the end. Ten inches below the upper end prepare two cross gains (10), each an inch deep and four inches wide. In these gains are placed the top rails (A), so the bolt holes in the gains (10) will coincide wit
the bolt holes (11) in the piece A. Below the gains (10) this post has a journal block (12), intended to be in line with the journal block (7) of the piece F.
Fig. 242. Tail Stock.
Then make a block (H) 2" × 4", and 6 inches long. This also must have a shaft hole (B), and a saw kerf (14), similar to the arrangement on the upper end of the post (G); also bore four bolt holes, as shown. This block rests between the upper ends of the lugs (C).
Another block (I), 2" × 4", and 6 feet long, with four bolt holes, will be required for the tail end of the frame, to keep the rails (A) two inches apart at that end.
