Dear Lee Valley,
is a project I worked on during the summer. The frame was
designed using computer-aided drafting (CAD) software and
made from four layers of 18mm Russian Baltic birch. There
are several hollow sections in non-critical areas of the frame,
whereas in the high-stress areas, such as the steering tube
and the bottom bracket, the use of custom steel components
needed to be designed and machined. The rear chain stay was
widened by hydrating the wood, and the use of several jigs
and clamps helped to maintain its final shape.
benefits of a wooden bicycle frame are its ability to absorb
road vibration, which it does with great ease, in addition
to attracting the attention of onlookers.
