Topic tags/keywords: bandsaw motor pulleys rpm

Hi everyone,

Hope that someone out there can help me. I have an old 14” Delta bandsaw and its 1/3 hp motor is giving out. I have a new 3/4 hp sears motor but it goes at 3450 rpm. Of course my old motor runs at 1750. My question is what do I have to do to make my new motor run the bandsaw? Do I have to change pulley sizes,etc. I really look forward to some advice and certainly thank all who respond.

Yes. You will have to either decrease the size of the motor pulley (1/2) or increase the size of the BS pulley (x2) or a combination of the two. In effect using the pulleys to slow down the motor speed on the BS.

Jim I really appreciate your answer. I knew it had to be something like that but I was not sure.
You have helped me greatly and I thank you. I’ll let you know how it works out. I guess I’ll go
to Grainger for the pulley.
