So I have a little time this morning before I hit the mowing tractor for one more day. Here is a nice short plan for a small filing machine.
I found it tucked away in a old file. Its titled PM Filing Machine. I uploaded a plan for a PM filing machine before but I don't think this version is it. It was in poor shape but I got it cleaned up nice.
I am sure when I find a day or two in the future, I want to try this. I could see it being a quick way to finish small metal parts accurately. I have a couple of small sets of Mibro files that would be perfect for this project. they have round shanks that would be perfect for a small chuck or collet.
