They look great. Here is what your gears may look like at the end of their usefulness. I got this gear from a lawn mower drive wheel, and cut it in half. the thin gear is from my pond filter pump. The bearing and race are from a tractor mower, (those and the fan blade are the only metal items), the fan blade is from a Reznor garage heater exhaust motor, the reel is a solder reel with some weathering, and the other pieces are items I thought would go well with the scrap load.
