For a final robot, i scream, NO WAY! for mock-ups, however, yes! one tiny hole won't kill you when you switch to a better system for the real thing. We have had recent luck with spring pins (available at hardware stores and small parts) for our mock-ups after breaking a few cotter pins.

For the real thing, a keyway is THE way. for those of you who are unfamiliar, ths involves milling a small slot in the output shaft of the motor, and buying a gear/sprocket with a slot or machining it with a broach. Then slip a square bit of steel between the two, and voila! This was a no-fuss, no-muss solution for us last year when we utilized two van door motors on our arm.

As for the drill motors, I must advise against the threaded shaft and left hand screw attatchment (this is the way bosch attatches their chuck). We broke so many of those stupid screws!
