How much are you into that mill for now?
Ya, I know..... don't ever add her up cuz you'll soon discover that you're eating $10/lb venison
So far I have a set of $2000 T-nuts, and a $500 bracket

A bit of an update on the motor conversion.
When I fired everything back up the idler pulley bearings were making an awful racket.
I removed the pulley and pressed out the bearings. They were open cage and completely full of dirt and grime from 30 years of use.
Took some measurements and ordered new sealed, lubricated bearings which arrived today.
Put it back together last night. What a difference the new bearings make. There’s only slightly more noise than from the just the motor alone. Very happy with the result.

More progress last night.
I was struggling with the VFD programming as I could not get the forward/stop/reverse switch to work correctly. I could only get forward or reverse.
I reached out to a member on Hobby-Machinist and got detailed instructions on how to program a specific part of the many configurations.
After a couple of tries I got it right. Now I have a forward and reverse switch! So darn cool!

It runs fantastic. The difference between single phase and three phase is palpable. The single phase motor felt ‘notchy’ if that makes any sense whereas the three phase motor is smooth as silk.
That's what I found as well. The 3 phase was smoother and quieter.
