Tim and Gael want to build a Hula bike .
Main Problem : how to easily displace the hub from the center of the wheel ? Play around with spokes ? No ! way too painful . But Tim is a carpenter and has access to a router .
So They decided to craft it out of plywood planks . Quick, easy, strong enough, not that awful, and works fine.
Step 1: Wheel building .
For this step, we used a router to cut two planks into circles . We cut them in two parts, at 1/3 of the edge to be able to put them around the hub. The hub being wider on its extremities, we couldn't simply drill a hole and slide it onto the hub . We took care to alternate the cutting directions , so the wooden assembly stay strong .
Also, we checked the 1/3 rapport was good enough to allow the wheel to spin without rubbing against the frame . It was a wheel from a smaller bicycle .
