After digging around, found none of the transformers I had were skookum enough to be used here, even if re-wound. Also, since I'm back to working full-time after the holidays, time isn't on my side. So I splurged for a giant chunk-o-wound copper: 800 watt 63 volt linear power supply. It's a very simple arrangement of giant toroid (doughnut) transformer and a few 0.1f caps. As a bonus, it's got an auxiliary +12v tap also, so I can power a cooling fan (dunna wanna melt lovejoy's spider) and any other accessories I may need in the future.
Since the Baldor motor is rated at 60v max, I also got a pair of Vishay power diodes rated for 100 volts and <ridiculous> amps. The voltage-drop across one will put me in the motors safe-range for voltage. The other one will be used as a "snubber" (facing backwards across the output) to eliminate the nasty voltage spike caused when inductors (coils) become disconnected from their source. Like this:
N/B: I'll check the PSU first, to make sure it doesn't already have a snubber.
110v [ POWER ] 63v --> DIODE -> 61.5v -> long wire -> 60v to motor
in -> [ SUPLY ] ^
[ ] 0v |
+--------+----> long wire -> 0v to motor
In other news, I received my shaft, couplers, and bearings yesterday. I also connected with a guy at my work that's willing to help me cut keyways in exchange for beer
I've also drawn up a quick sketch of a motor mount, which I'll post if anybody's interested in reviewing or (constructive) criticizing.
