I'm working on rebuilding a 1944 12" CK:
I've already replaced the original 1200RPM motor with a ABB/Baldor 3HP 1800RPM motor and a Teco L510 VFD with a rotary switch configured for 40Hz (1200RPM), 60Hz (1800 RPM) and 80Hz (2400RPM) to get original labeled speeds as well as 1.5x and 2x, as that machine had a stock maximum of 550RPM on the headstock. Had to fabricate a simple adapter to fit the smaller new motor in the right place. Home shop, so picked the 3HP as something feasible to power off a single phase 220V VFD, if I had realized at the time that I could have used a 10HP 3PH VFD to power a 5HP 3PH motor off of 220 single phase I would have gone that route.
If anyone wants the original 3HP motor, it still ran when I took it out but not in great shape. Local pickup from S.W. Indiana, $50.
I've taken apart the TA, replaced all the bearings, cleaned and repainted it.
Currently have the apron, cross slide, compound, and saddle disassembled, for cleaning, repainting and new bearings. Making new sleeves for the clutch handles as both were worn out (thanks to Keith Rucker's Youtube video's for some hints there as well as overall good motivation).
I'll post more pictures as I go.
And then yesterday I picked up a 1964 10EE, 20" bed, original 5HP motor and change gears and ELSR. That will be my next project when the 12" CK is done.
