Question regarding old 14" bandsaw (motor/pully/speed)

Hi all!


This is my first post here! It's great to be here. I hope you can help me here.


I recently bought an old/vintage 14" bandsaw. Not sure of the brand because it's not stamped/indicated anywhere. It's basically a Delta clone, I believe. It does say "Made in Taiwan" on the metal stand.



When I look at the motor, it is 1 HP. The pulley has two wheels, which I'm assuming means that I can decide which wheel I'd like to use to alter the speed (by changing the belt to one or the other wheel of the pulley). One wheel is larger and the other more distal one is smaller.



Which pulley wheel should I put a new belt on? The larger one or the smaller one? What is the major difference and which is better for what?


Thanks in advance!

The larger pulley will run the blade faster. Is there only one pulley on the bandsaw (two on the motor)? Set the bandsaw up with the belt on the smaller pulley and test it. If it feels like the blade needs to run faster then you have choices. There are hard and fast guidelines available online if you want to do the math for the blade speed but I don't worry with it. My motor has a 3-step pulley and I don't recall which one the belt is on but I haven't changed it in the last 10 years.

Sounds like it is a two speed saw, larger motor pulley for cutting wood, smaller for nonferrous metals.

I would use the highest speed. Higher speeds are usually used for resawing. While slower sped for curved cuts.
Cutting steel requires very slow speed.
I doubt the low speed is close to being slow enough.
Look online for band saw blade speed calculator.
On my Delta 14" saw I use a 4" motor pulley (1725 rpm) and a 8" saw pulley to get 3160 fpm blade speed.
Works for me resawing and curve cutting.
