This morning, picked up a piece of felt and Wal-mart and had to go to Home-Depot for the rubber surgical tubing (Plumbing department). They only sold the surgical tubing in about 3' lengths, so I had to pay $14 for 3' of rubber tubing when I only needed 2 inches. Guess I'll never run out. Then, the little "axle" (don't know what else to call it) coming out of the motor had a pretty small gear on it, so I tore a thin piece of duct tape, wrapped about 3" worth to build it up, then turned half the surgical tubing inside out and rolled it over the tape (tight fit!). For trial sake, I used an aluminum shaft I had left from several years ago and plugged the tip end into the opposite end of the surgical tubing, and let 'er rip. Spins perfect and quiet with very little friction with the felt.
Next week, going to dip some old aluminum shafts and try this painting stuff out.
