Help! My Crankandstein broke!

[Professor Frink]

I've managed to strip the hex-input on my driveshaft for my drill, so now when I put a hex bit in there, it just spins around without pushing the rollers. Is there anything I can do about this? I looks like the driveshaft is part of the roller assembly (it's the 2S model).

I just mount the chuck of the drill on the outside of the driveshaft. It grabs enough that it spins the rollers well. I've crushed at least 50 lbs of grain like this with no problems.

That's a good idea, I never thought of that, thanks!
