drill bushing is used to act as a support and guide for the hollow drill. Make the bushing from aluminum tubing slightly shorter than the 3-inch hollow drill, with an inner diameter sufficient for insertion and rotation of the hollow drill and an outer diameter which will fit freely into the screw holes in the windshield. Insert the drill and bushing into a windshield screw hole as a test to ensure that the drill will not bind in the holes.
