[GrizHFMinimill] Re: $50 mini-mill power feed

Thanks Rick. I tried with some black plastic last night using a plumbing torch but only did the first part you mentioned. So, it came out a little wavy. It looks so crappy, it kinda looks like part of the accordion. :) But, it works. I could not and would not have done the DRO without your inspiration. I did it about twice -- hitting many of the space issues that I think you may have hit too. It ended up being one of the most fun projects I've done in years.

Thanks so much.

I found a supplier for a similar motor so I ordered the supplies for the power feed. I'd still love to see pics or hear more about that cam lock clutch. I know it's a pain to tear it down for pics, but I'd really appreciate that and I think I'm not alone.

I also would not recommend torque less than about 4 in/lb or RPM under 120.
