I ran the numbers on trying to get that motor down to ~300 rpm and it was going to take a HUGE pully to get it done. I will make a polishing station out of that motor and look for another to power my mill. Speaking of mill... I have been working on it.
I was actually inspired by this thread
So, a while ago, I picked out a piece of 1-3/4" diameter steel from the scrap bin. (yes, the boss said I could have it...)
I talked to my machinist and we are going to work out a deal with homebrew and maybe some $ for the machining duties.
This is what I have come up with as far as design. The rollers are 1.75 diameter x 6". The adjustment knobs have an eccentric hole in them that mounts the bronze bearing and thus will allow the mill to be adjusted. I have some fine tuning left to do on the adjustment. It actually adjusts way too much right now.
Here it is in full view:
Here is a view sectioned longitudinally through the driven roller.
