I notice that those stepper motors were 150 ox in motors. I would suggest
300 oz inches would be better. I put those (300) on my retrofit and they
worked very well. One other thing you may want to do is the replace the X-Y
leadscrews with ballscrews. On my mill drill I found the original acme lead
screws had a pitch error of .001 per in and .02 back lash. With ballscrews
I have <.002 and the pitch is right on. I also solved the mill drill quill
backlash problem (.02) by modifying the pinion shaft and making some simple
eccentric bushing for the pinion shaft. I have a write up on it somewhere.
It was easier than adding ballscrews to drive the quill.

Subject: [CAD_CAM_EDM_DRO] Some pictures of a retrofit
Group,
I was talking to a manufacture of a CNC controller and they invited me
to come to their shop and look at a HF mill that had been retrofit.
This weekend I was trying to figure out how the free web storage space,
from my provider, worked . Here are some pictures I took with my Sony
Camera: . Their setup looks
fairly simple. So much so I think will try to retrofit rather than buy
one of the small CNC mills. Perhaps, someone else on the list will find
the pictures helpful.
