218. The Frame with Wire Braces.]
Mounting the Frame on Bicycle Wheels.
We were now ready to mount the frame on the bicycle wheels. We
used only the front wheels of the bicycles with the forks in which they
were journaled. The shanks at the top of the forks were firmly driven into
holes in the crosspiece near the ends. For the steering wheel Bill took the
front fork and wheel of his new bicycle, letting the shank into a hole at
the stern end of the backbone.

The Tiller.
For a tiller we used a piece of an old rake handle. A small hole was first
drilled into the handle and the end of the stick was then split through
the hole, permitting the projecting shank of the fork to be driven tightly
into the hole. The split wood was now tightly closed onto the shank by
means of a bolt (see Fig. 220). In the rubbish heap we found an old chair.
The legs were sawed off and the seat was then firmly nailed to the
backbone. The back of the chair was cut down so that it just cleared the
tiller.
