First, Grizzly makes good shit.

Now, rewire a motot if it's mutli phase? Yea, I don't know what that means either.
But, there are 110/220 motors, they convert from one to the other easily.
But, multi phase?? is another thing. There's single phase and 3 phase 220. If you buy a ebay 3 phase motor, you'll need a phase converter (like $600) JUST to convert from 3 to single phase, I have one on my gear lathe. Houses are single phase, industrial buildings can be 3 phase.

The motor on the link doesn't say what phase it is AND it's a blower motor not designed for tooling (not much torque on startup).

I wouldn't buy a motor off ebay unless it was brand new, it may be smoked, worn out, etc.

2 horse is a lot to just run a band saw too.

What you need to check: The frame number - this needs to be matched because of the mounting, hole locations in the mounting plate,etc. And you need to measure the shaft dia. on the old one so the pulley fits.

Personally, I'd look at a 110v, horse or horse and a half at Northern Tool or even Harbor Ft.

Also, if you have 110 in the shop, you have 220 too. It's easy to run a 220 line from the breaker box.
I did it in my shop and I'm NOT an electrician.

Bill, on the same track on a lot of that. The first thing I did was look into running 220 into my garage because I was under the impression the saw ran when I bought it. Problem is the breaker box is a long way from the garage and the length of cable and box and plug I would need just to run a 220 to my garage is a LOT more than A: I can afford and B: I paid for the saw.

SO, lets assume I want 110 just simplicity and budget.

The label on the motor in the Ebay link says it's a 3 phase so that means it's not an option. Unfortunate considering the cost of motors. Even new motors are more than what I paid for the saw.

I'm less worried about the mounting bracket size. The plate under the saw is very versatile in it's design, and I could fab up a new plate quick and easy if I needed to. Shaft size is also not as important if I find a good deal because I have access to a lathe and can either bore the pulley out to fit the shaft or fab up a sleeve to bush the difference.

My end goal is to get a motor under this saw as cheap as I possibly can. I'll buy used if I can simply because the costs are so much lower and it's just a band saw. If it starts and rips what I need ripped then I'm not going to worry if it's not as strong or precise from years of use.

SO I need to make sure I find a single phase motor, based on your incite. I like the option of a weaker motor, since the 1 HP motors are cheaper, though I don't want to shoot myself in the foot by installing a motor that won't cope with the materials I may end up cutting with this saw.

Heck I'm hoping even maybe one of you guys may have a spare motor that might fit my needs and we can work something out.

Thanks everyone for your time and opinions on this.
