Lightly Sanded BSA Wheels

This wheel should be legal in pinewood derby races that specify any of the following:

  • Wheel diameter must be greater than 1.18".
  • Wheels must be the original shape as packaged in the Official Cub Scout Grand Prix Pinewood Derby Kit. (Wheels must not be peaked, ‘H’ed, humped, tapered, or narrowed.
  • The only work allowable to any wheel is to remove manufacturing defects such as burrs or injection flanges.
  • Wheels may be sanded until the mold seam is removed. Wheels are not to be turned on a lathe, completely smoothed or modified. Some of the original surface must still be visible.
  • Wheels may not be tapered or rounded. The wheels may be slightly sanded to remove any mold marks but may not be modified in any other way.
  • Only the Official Scout Grand Prix wheels may be used. Wheels may be sanded (smoothed to remove knit/mold lines) but the wheel’s profile may not be altered. Wheels that have been turned to create a reduced contact patch (beveling, tapering, thin sanding, wafering or lathe turning) as determined by caliper readings (and, or visual observation by committee officials, decision final) are prohibited.
  • Wheels may be lightly sanded and polished to remove imperfections. This light sanding and polishing is the only wheel modification allowed.

And similar rules.
