Bill had figured it out some way that the ends of the boards
should be just about 5 feet 10-1/2 inches apart. When the boards were all
arranged we nailed them together at the center, and connected the ends
with narrow tie boards, as indicated in Fig. 256.

The Buckets.
Eight large tomato cans were now procured and fastened to the spokes
at the ends on the inner side, that is, the side the hub was nailed to. We
couldn't very well nail on the cans, so we punched two holes in the side of
each can and then secured them to the spokes by passing bolts through
these holes and the boards.
The Paddles.
Then we cut sixteen paddles of the form shown in Fig. 257. Eight of
these were 12 inches long, and the rest measured 18 inches. A slot 3
inches deep was cut in each paddle of just the right width to slip over the
tie boards. The shorter paddles were fastened on just back of the spokes,
and the rest were secured half-way between each spoke. The paddles were
braced by stretching a wire from one to another all the way around the
wheel.
