Axle Polishing Kit
for Pinewood Derby Racing

To polish your pinewood derby axles to a mirror finish, you need a set of coarse to fine polishing papers or compounds. These industrial grade cushioned abrasive papers are designed for polishing metal to a high shine, and are thus ideal for polishing pinewood derby axles.

The kit consists of one each of the following 4" x 3" papers, and instructions. Note that the last two papers are much finer than any readily available sandpaper, and are finer than pumice. One set of axle polishing papers is enough to polish 8 axles. To polish axles, cut each paper into 1/4 inch strips, 3 inch long (there will be 16 strips per paper). Then fasten a drill in place using a Drill Mount, vise, or clamp.
  1. Insert an axle into the chuck of the drill, and start the drill.

  2. Use a file to remove the ridges on the axle head and shaft (if present).

  3. Dip a strip of 30-micron paper in water and apply it to the spinning axle for at least 10 seconds. Polish the portion of the axle on which the wheel will spin, and on the inside of the axle head.

  4. Repeat step 3 with a second strip of the same paper.

  5. Repeat steps 3 and 4 using the 15, 8, 5, and 3-micron papers in order. Use two strips of each paper type per axle and don't forget to dip each strip in water.

  6. Repeat the above steps for each axle.
