I have an old band saw (Babbitt bearings) that I would like to get running. The saw is in great shape but it needs a motor. I have a 3450 rpm motor that I would like to use but I think that it will be too fast. I can't find the book that I know I have somewhere that has the formulas I need but from memory I calculated a blade speed of1805 fpm blade speed. I have a two inch pulley on the motor and a 12 inch pulley on the saw. The saw has 20 inch wheels. Does that number seem right? Also, what should the blade speed be?

From contributor J:
If I remember correctly, you want to be between 700-800 fpm. You'd be good with a 1725 motor I think. I had a 30" saw, 4" pulley on the motor, and 12" on the saw with a 1725 rpm 5 hp Baldor. It ran great.
If it were my saw I would look for a 2-3 hp 3 phase motor and power it with a VFD. It should be about the same cost as a single phase motor. It will give you better control over the speed of the blade.
