Fig. 9.—An Eight-blade Windmill.
You will see by Figs. 10 and 11 that the blades are nailed to the side of short spoke sticks, and the sticks are driven into holes bored in the spool hub. The hub turns on the rounded end of the shaft stick (Fig. 12), and the square end of this shaft is slotted to receive the fan-shaped tail (Figs. 12 and 13).
For the Hub use a large ribbon-spool. You can get one at any drygoods store. Locate eight holes around the center of the spool at equal distances from one another, and bore these with a gimlet or bit, or cut them with the small blade of your jack-knife.
Cut the Eight Blades 6 inches long, 5 inches wide on their wide edge, and 1½ inches wide on their narrow edge. Prepare the hub sticks about ½ inch by ¾ inch by 4½ inches in size, and whittle one end pointed to fit in the hub (Fig. 11). Fasten the blades to the spokes with nails long enough to drive through the spokes and clinch on the under side. Glue the spokes in the hub holes, turning them so the blades will stand at about the angle shown.

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 [Pg 7] 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.
Figure 14 shows how the toy windmill may be rigged up
Fig. 14.—How the Windmill may be Rigged up to Operate a Toy Jumping-Jack.
To Operate a Toy Jumping-Jack, by supporting the jumping-Jack on a bracket, and connecting its string to the hub of the windmill. You can make your jumping-Jack like the one in Fig. 110, the details of which are shown in Fig. 113.
Cut the upright of the bracket (A, Figs. 14 and 15) 14 inches long, and the crosspiece (B) 7 inches long. Nail A to B, and nail the jumping-Jack at its center to the end of B (Fig. 15). Fasten the triangular block (C) to the lower end of A, and then nail both A and C to the edge of the shaft at a point that will bring the string of the jumping-Jack a trifle beyond the windmill blades.

Fig. 16.—Spool Hub.
Fasten a small stick with a brad driven in one end, in notches cut in the hub's flanges (Fig. 16), and connect the brad and Jack's string with a piece of wire or strong string. Then as the windmill revolves it will operate the toy in the manner indicated in Figs. 14 and 15.
