Hi,
I've just been looking at recommended narrow bandsaw speeds Bob and as expected there is a huge variation. Working in feet per minute then the lowest speed for wood cutting is about 1,000 FPM and a bandsaw at this speed with the correct blade installed will also cut aluminium. For general wood cutting I suggest around 2,500FPM.
Once you have your new motor and know the motor's speed then you can work out your pulley sizes because you already know the band-wheel diameter.

Band-saws can bite so I've added a couple of links above because many novices will read such threads as this and better forewarned than lose fingers or a hand. Never ever open a wheel guard with the saw under power otherwise you might seriously regret doing so and please do not be tempted to push small items through the saw bringing your fingers inside the danger area near the blade.
Your American Walker saw looks the business Bob and should give many years of reliable service; you seem to be collecting band-saws the way I collect lathes?
I worked at Brook Motors for 24 years Bob and you've shown me something new. I've never seen such a small DC motor made by Bull (Brook) . Bull DC motors were made in the Ipswich factory which I never visited me being based at Brooks headquarters here in Huddersfield but I've handled hundreds of huge Bull motors both by overhead crane and fork-truck; I know nothing about DC motors other than the very basics. You got a bargain though and I'm sure you'll find a good use for it.
Kind regards, Col.
