How to use the Wheel Mandrel on Your Pinewood Derby Car
This
mandrel is used to mount wheels in a drill or a lathe in order to polish or machine the wheels. The mandrel
can also be used in a dremel.
The wheels can be mounted in either direction to aid in polishing the inside edge of the wheel.
The mandrel screw has a beveled face to ensure that the wheel is centered on the mandrel screw.
Tighten the mandrel screw unitl the wheel is firmly in place, but do not over tighten as the wheel could be damaged. This is especially important for wheels made with a softer plastic, such as those supplied by Awana.
When the wheel is mounted, spin the wheel while holding it lightly against a sandpaper block.
