There are several things to do with spare parts: sell them for scrap metal, finally fix up that old car, or, if you're feeling especially generous, give one to Paul Walker. Now letting spare parts be generous to your wall, reCycle Clocks.
Started by a motorcycle safety instructor (who was already making art out of rusted wrenches and vintage hubcaps) after she was given an old rotor, these unique wall clocks are constructed using spare motorcycle/bicycle rotors and sprockets that're all hand polished/assembled, and sourced from craft fairs and by "sweet-talking mechanics", who also somehow managed to convince Mike to leave that sweet gig with Genesis. Motorcycle part-based time delivery systems include a number with a black face and heavy stainless rim constructed from a Galfer racing rotor; a polished metal-backed one fitted with a smaller second circle at six o'clock via an engine chain; and a clean vintage-looking design made from a custom-rusted/copper-treated Triumph rotor, which any of the Killer Bees can tell you, spreads germs as it turns. On the bike side there's a ninja-star-ish chain ring mounted with an offset brake complete with cable, a 6" chain-wrapped sprocket backed with metallic blue, and one with a small inset face constructed from two sprockets (one wrapped in a bike chain) that are arranged in a double stack, or at least they were, until things got nutz with Proximity Mines.
RCC also slings simple bracelets constructed from scooter and bicycle chains, as well as aphorism-arted motivational photographs like a useless stop sign printed with "stop at nothing", and a lonely island that's "not on prime time", though neither is Walker -- that dude just couldn't catch a break with the casting director on Cougar Town.
