Motor size question, too big?
the logic of a 3 phase is simple. you more power because of the three coils. using 3 phase, you have each sine wave running at 60 cycles, so you have less gap between the waves. it delivers more torqu

Hi Neighbor, It looks like 142037 if that is correct, it would make it about July, 1943. not the right year. I will take a flashlight and triple check. I did not think it was that close ! Dave Browns

I thought the A had a power cross feed and QC gear box. the B had only the QC gears and the C was manual in both respects ?

the tools needed are far-far less than what it would take to change the dials to large dials. if you have a hand saw and some metal, you can make the holder. you should have a dial indicator already.
