Overview: The Pro Wheel Mandrel is a precision machined tool designed to hold Derby Car Wheels for preparing them for racing. It features a knurled knob for tool-less use, a stepped shaft face for reverse mounting of B.S.A. wheels and a stepped body for use in all low speed rotary tools. This precision-machined tool will accurately mount B.S.A. Pine-Car & Awana Derby Car wheel in the chuck of a drill or lathe. Benefits include: Accurately machined shaft allows for precision use in any drill chuck or Dremel-type tool. Step-down on shaft allows BSA wheels to be mounted with the ‘spokes’ facing the drill chuck, simplifying work on the inside edge of the tread. Knurled thumb screw eliminates the need to use a screwdriver to mount a wheel (a clumsy operation with the standard mandrel). Beveled thumb screw ensures that the wheel mounts accurately on the mandrel. Screw can be replaced should it be lost or bent. :

kids have won many derby's with it.
easy to use and makes great wheels when used correctly. low speeds in a secured hand drill or drill press, never a dremel, way to fast. we always use 220 and 600 sandpaper wet.

Teach Unexpected Lessons to your Cub Scout
I was hoping to be able to teach my 8 year old son about woodworking while building his pinewood derby car, instead I spent more time explaining about how to not cross thread a wheel mandrel...In short it is much easier to cross thread the screw on this mandrel than it is to thread it correctly, and it proved to be very frustrating for my son. Not sure if other brands have a similar problem but if I could go back in time I'd try a different brand first.

Broke on second wheel
I was using this on a dremel that was held by a soft vice while I held sandpaper to the bottom of the wheel. The dremel dipped slightly and the mandrel head snapped off. I was on my second tire. Obviously my fault for not securing the dremel tightly enough in the vice, but it's not like the dremel or mandrel fell to the ground. It simply shifted in the vice and the pressure of me applying sandpaper was enough to snap it. I threw the broken mandrel away and finished the job using an axle nail. Worked much better than the mandrel. I found the axle installer a much more useful tool.
