That is assuming you have access to a lathe, of course. If not then maybe braze one of the metal high strength VEX gears onto the end of the 1/2" bolt?

Better method than glueing a VEX shaft into a round hole: drill a press fit hole for 1/4". Then take the metal VEX shaft coupler, and press fit it into the hole.
