Description
This is a wheel hub for using a standard CD as a wheel on a gravity car. The hub is designed to be used with a #8 wood screw. The CD is held on the hub using the circular friction-fit clip. The jig is used with a brass insert to facilitate drilling a perpendicular 1/8 inch hole for the #8 wood screws.
