I saw this on Facebook today in the Unplugged Woodworkers group: Unplugged Woodworkers | Facebook
The poster said: "My final project on the wood craft teacher school, 24 years ago. Most people built a chair, but I wanted to do something mechanical, like a pedal contour saw.
I did not have time to make a wooden chain as a drive, but an inner hose had to be the solution."
