Hello,
Im trying to adapt a dremel chuck to fit the end of a stepper motor. The dremel chuck uses a 7mm input shaft with pretty fine threads. regular metric goes from 6mm to 8mm, nothing in between. Any idea where I can find such a beast?


Thanks,
Ben

I'd just take the mating end of the dremel shaft off too (maybe whack the end off of a beat up flexshaft) and connect it to your stepper with a coupling.

Otherwise, fire up a lathe and cut what you need. Travers tool has a good selection of odd size taps and dies. www.travers.com.

Good luck.

www.mcmaster.com maybe?
