Tool PWD Hub

Prepare Pinewood Derby wheels for smoother, more consistent performance with the Pinewood Derby Hub Tool. Precision CNC-machined for accurate wheel preparation, this sizing tool helps ream and straighten undersized wheel bores for improved axle fit and rotation. It can also square the inner wheel hub to the wheel bore, helping ensure proper positioning when using a wheel mandrel. The tool also allows the inside wheel hub to be accurately coned, reducing the amount of hub-to-body contact that can create unnecessary friction. Use it as part of your Pinewood Derby wheel-preparation process to fine-tune fit, alignment, and rotational performance before race day.
