Figs. 72 and 73.—Details of Water-motor Wheel.
Cut eight paddles from the cigar-box wood 1 inch wide and 5 inches long. Take a pair of these strips and fasten them to one can cover, in line with each other, and close against the sides of the cover (C, [Fig. 73]). Fasten with tacks or brads driven through the cover into the ends of the strips. Take another pair of strips and fasten them to the same cover, in a similar manner, at right angles to pair C (D, [Fig. 72]). Then tack the pairs of strips E and F to the cover halfway between pairs C and D. With the paddles in position, locate the exact center of the end of the can cover, and drive a nail through at this point into the end of axle B. Slip the free ends of the paddles into the other can cover, and carefully drive tacks or brads through the cover into them. Drive a nail through the center of the cover into the end of axle B.
The Wheel Supports. [Figure 74] shows the supports for the wheel. Cut the end pieces G 4 inches wide and 6 inches high, and the cross strips H 1¾ inches wide and 5½ inches long. Nail pieces G to H, as shown, allowing the lower ends of G to extend ½ inch below strips H, and leaving a space of ½ inch between strips H. The axle holes in pieces G ([Fig. 74]) should be located in the center of the width of these pieces, and halfway between their tops and strips H. Bore the holes with a gimlet, or make them by driving a large nail through the pieces, and then withdrawing it.
Fig. 74.—Support for Water-motor Wheel.
To Mount the Wheel upon the supports, withdraw the nails driven into the ends of axle B, slip the wheel between uprights G, and drive the nails through the holes in G back into the holes in the axle ends ([Fig. 71]).
