one of the paddles, and Fig. 4 shows the method of shaping the
paddles. To make the frame, several lengths of scantling 3 in.
wide by 1 in. thick (preferably of hard wood) are required. Cut
two of them 4 ft. long, to form the main supports of the frame,
AA, Fig. 1 ; another, 2 ft. 6 in. long, for the top, B, Fig. 1;
another, 26 in. long, to form the slanting part, C, Fig. 1; and
another, D, approximately 1 ft., according to the slant given C.
After nailing these together as shown in the illustration, nail
two short strips on each side of the outlet, as at E, to keep the
frame from spreading.
Cut two pieces 30 in. long. Lay these on the sides of the frame
with their center lines along the line FF, which is 15 in. from
the outside top of the frame. They are shown in Fig. 2 at GG. Do
not fasten these boards now, but mark their position on the frame.
Two short boards 1 in. wide
[Illustration: Detail of Homemade Waterwheel]
by 1 in. thick (HH, Fig. 2) and another 1 in. by 1-1/2 in. (I,
Fig. 2) form a substantial base.
Cut the wheel from sheet iron 1/16 in. thick, 24 in. in diameter.
