Sam and Lucky, thanks!

The phase converter circuit I'm using is a pony start with capacitors to balance the three phases... it's supposed to be specifically for CNC machines, which are picky about that... is this what you describe?

It's the one here:
Phase converter for cnc

It sounds like I should do at least a partial tear-down and cleanup before I do anything to try running it. I'm rigging up a chain fall supported by 4x4s so I can re-mount the head, I suppose I'll leave that in place so I can lift the table and other parts.

I ordered Mobil way oil, spindle oil, and some Kool Mist coolant from McMaster-carr yesterday, so I'll plan on draining the oil from the Bijur units and replacing it. I'll also restrict my naval jelly use to non way surfaces. There's really not that much rust anyway. The table top has the worst of it, and it was already damaged from a tool bit crash... I was planning on having/making a tooling plate for it anyway.

The drive ballscrews have almost no rust or other problems.. I think because of the type of metal they are? They look nice.

Looks like this weekend I'll have time for scrubby pads, simple green, and elbow grease. Pics after that.
