I'm in the process of rebuilding an old 12” X 48” Fay & Egan flat-belt lathe, It originally had a 4 step drive pulley connected straight to the motor. My plans are to put a 4 speed Drive-All gear-box in the same location as the original motor, Then the gear box will be belt driven from a motor mounted below the lathe.
The gear box originally came off of a South-Bend metal lathe & has a ratio of ruffly 1:1, 2:1, 3:1, 4:1, There's an 8” pulley on the gear box & a 4” pulley for the motor. If I kept this same pulley ratio I would end up with about a 2400 RPM high speed & about 80 RPM for a low speed.
Being that the pulley size's & ratio from the motor to the gear-box will delegate the highest speed achievable. I'm trying to figure out what ratio would be best to use to get the highest speed needed?
My main use of the wood lathe will probably be mostly for 2” X 2” or larger table legs & bowls, So I doubt I would really need anything over 2400 RPM?
