Just an idea

We are trying to do the same thing: use the drill motor w/o the gearbox.

I think that Ryan's original question is concerning just how do we mount this drill motor if we are not using the gearbox... it's not very straightforward.

I see two options:
1. Use the two holes on the output face of the motor as pilot holes for a #10-32 or M5x0.7 tapped hole. If you were to do this, you would either need to use a metal forming tap instead of a cutting tap. Or, you just need to put grease on your cutting tap and go slowly through the hole... bit by bit... wiping off the grease and metal pieces for each turn or so... then putting grease back on the tap before cutting again.

The whole point of being careful, of course, is to not get metal shavings in the drill. Since the drill motor is worth $23, it's worth taking your time to do this.

2. Use the holes on the side of the motor. The same care would be needed when you tap these holes also, and they are in a non-convenient position. You would have to make a bracket (or 2) to get the motor mated into the gearbox, and that is kind of a waste. Also I don't see a good way to insure the motor's position when doing this.

I suggest option 1. We have not tried it yet, but we probably will within a few days. I'll post again to let you know how it goes.
