16 year old Marco Facciola built a bicycle made entirely out of wood:
This project came to mind as I was reflecting on the many stories my opa, Case Vandersluis, told me about his adventures in Holland during World War II. Opa was roughly the age I am now when he had to build wooden wheels for his bicycle, as rubber was scarce during the war.
The method behind his madness:
I was mostly concerned that the wooden chain would break. I researched the strength of different types of wood and built jigs to test the stresses that each of the chain’s components would undergo during use. First, I used my weight (150 lbs) to see if the wood could endure this amount of force. Then, my father would stand on the jig. I calculated that my dad’s weight would be twice the force each chain component would need to withstand. I made the specs high to ensure the chain and sprockets would work even if the wood had imperfections. During testing, I made adjustments to the chain’s components, and once I had it figured out, I realized that completing the project was within my grasp.

Might this make for an excellent collaborative project between ASIC and Fine Arts students?
