WINDMILL AND WATERMILL
Plate XII DRAWBRIDGE
(Chapter VII)
To make the toy technically correct, the buckets should rest against a solid wheel contained within the two outer ones, as in Fig. 313, so that no water can run down toward the centre of the wheel. This can be easily managed, if desired, in the following manner:
Before fastening the wheels to the reel, cut a long strip of paper, with flanges, as in Fig. 316, in which a b is the distance between the two outer wheels. Describe a smaller circle on one of the wheels, about 3 inches in diameter; glue the reel in position, then bend down the flanges of this strip of paper (Fig. 316), and gum these round the smaller circle of the wheel. Now gum the other wheel to the reel and to the flanges of the paper.
