Making Perfectly Round Wheels
If you need a pair of wheels (or maybe even four), scribe circles on your stock and cut the wheels out on the band saw, staying just outside the lines. Drill a 1/4" hole at the center of each wheel, then slide the wheels onto a 1/4" threaded rod and tighten with nuts. Chuck the rod into your portable drill, clamp a wooden guide block onto the table of your disk sander and, with the drill in reverse, sand the wheels to their final size.
