How to Polish the Wheel RimHow to Polish the Wheel Rim

A rough wheel rim edge can slow your Pinewood Derby car down when the wheel rubs against the track's center guide rail.

The Wheel Edge Polisher will smooth and polish the wheel rim making your car faster.


Instructions

The Wheel Edge Polisher kit includes:

  • Polishing disc
  • 2 rough sandpaper rounds
  • 2 fine sandpaper rounds

1. Peel the backing off of one of the rough sandpaper rounds. Center it over the disk then press it on one side of the polishing disc.   Use the same technique to attach a fine sandpaper round to the other side of the polishing disc.

2. Place a wheel, rim side first, on the rough side of the polishing disc. Turn the wheel several complete rotations using moderate pressure and turning in both directions.

Speed tip: If you have some dry graphite powder, rub a small amount on the fine side of the polishing disc.

3. Repeat the procedure on the fine side of the polishing disc.

4. Use the same procedure for the remaining wheels.

Replace the sandpaper rounds with the spares as they become used.

Sandpaper round refills are available from this web site.
