I drew my inspiration from a wall of clocks for sale in a store. I thought about making clocks from round objects that were designed for other uses such as car speedometers and bicycle gears. After a few trips to the junk yard and the bike store, I had the substrates for the project.
The hardest part of the project: cleaning off years of dirt and grime from bike gears
The most fun: seeing the finished projects
The most challenging: drilling through the metal bike parts
