I purchased a 1968 Clausing Colchester 13x36" about a week ago for a great price. The reason being the previous owner wired the lathe up wrong and destroyed the three phase motor. However, since it was a 3HP motor from the factory, a single phase motor is viable and that is my intention. The only issue is the previous owner tossed the motor - along with the drive pulley. My problem is I cannot find any drawings of the pulley I need to make for the new motor. It is a double v-belt design, and seeing as my motor RPM was 1800 and the fastest speed of the lathe is 1500, I know it's probably a smaller diameter than the headstock pulley (17% smaller, maybe?), but other than that I'm in the dark. Also, the lathe was a two speed model, and I'm not very familiar with how Clausing did this (if it was some sort of variable pulley attachment or a phase/Hz reduction).
tl;dr - Could anyone with a Colchester 13x36" late 60's lathe please photo your drive motor and pulley for me? Which direction does the motor run in it's standard setting? If anyone has a drawing or could take some basic dimensions for me it would make my life a lot easier. I have been unable to locate anything of use online so far. I just need a place to start this conversion! Thanks in advance for any help!
