I recently bought a Delta/Rockwell 14" bandsaw from the early 80's. I bought the machine only, no motor. I have a 1hp 1750 motor for it. My question is what size pulley should I run on the motor to get the right blade speed for general woodcutting. The pulley that came on the saw is 6".

The larger motor should deliver same speed. It's just stronger so it wont bog down on you.
I'd call Delta and enquire about this. They might be able to provide you with an answer.

For a sawblade speed of about 3100 feet per minute you'll need a 3 inch drive pulley with the 6 inch saw pulley. I'm not sure if that's the proper speed but it ought to be close. A 2 inch pulley will turn around 2050 feet per minute.

My Grizzly saw has 3000 FPM on the label so...and my math shows a 2.5 inch pulley on the motor will yield about 2700 FPM....me, I'd go the 3 inch pulley on the motor and make sawdust. Someone else may jump in with better advice.

My 14 inch Rockwell/Delta 28-243 has a 6 inch pulley on the saw and a 2 3/4 pulley on the 3/4 hp motor. I bought this saw used but I think it is the orginal set-up. Does yours look like this?

Thank you all for your input. After looking at all the recommended sizes I think I will try a 3" for starters. Cannon 84, thanks for the chart and photo. Mine is a little older, a 28-200 and the only difference is the upper and lower covers remove with two knobs as opposed to being hinged.
