The wheels are the little nylon/plastic wheels you buy for replacements for your sliding screen door. They are epoxied on with 5 minute epoxy. You must line up the wheels, one over another, so the belt makes sense. The drive belt is 8 wt fly line, simply tied with an overhand knot. You must wrap the fly line not only over each wheel, but around each wheel. It must make a circle around the wheels. I had to play with this to make it work. A person could allow the drive wheel bolt to be cut off, and attach the drill/motor directly to the bolt. It would keep you from adding the additional belt. That was an afterthought. The entire thing was built for under $30.00, and that included the drill, purchased used from the local pawn shop.

This little set up can be made with six cups (the cups are one inch plastic caps for Schedule 40 stuff, with a hole drilled in the center. The cup is then drilled with 4 little holes, and little pegs are used to hold the rubber bands. These little holes need to be drilled right at 90 degrees on the circle, or the rubber bands won't " X " at the center.

I ended up changing the drill out, using a regular drying motor from Cabelas.
