Fig. 10.—Spool Hub. Fig. 11.—Blades. Fig. 12.—Shaft. Fig. 13.—Tail.
The Shaft should be made of a hard wood stick about ¾ inch by 1½ inches by 30 inches in size. Cut the round end small enough so the hub will turn freely on it, and punch a small hole through it so a brad may be driven through to hold the hub in place. Cut the slot in the square end with a saw.
Cut the Tail of the shape shown in [Fig. 13].
Pivot the Windmill upon the top of a post support, in the same manner as directed for the other windmills.
