Couplings or wheel hubs for cordless drill motors

I posted some design info and pictures of a robot I'm working on to the main LMR robots listing. You can check it out here

As I indicated in the post, however, I'm having trouble coupling or interfacing some cordless drill motors (the Harbor Freight 17v kind which I have read many people use in their bots) to some 1/4" screws, which are the axels of the wheels on my robot.
