Will this motor work well for a 2x72 Grinder build?

It will work better in Shoptalk, where this kind of thing gets discussed regularly. General Knife Discussion is for discussing knives.
 
Looks like it's a TEFC 1 HP and 1730 RPM.......that'll work just fine!:thumbup:

I agree. I would run a 6" drive wheel which will give you 2700 sfpm which is kind of in the middle if you aren't going to do pulleys.
 
I would give a small word of caution against using only 1 horse power if your building a 3 to 4 wheel grinder; especially if you plan on using step pulleys and a belt. It would work "OK" if direct drive, but then you're only limited to one single speed, and either way, you'll likely be finding your self wanting a little more power.

Now if the price is good and it's all you have available at the moment, by all means, go for it, but if you can find something similar with 1.5 to 2hp, I think you'll be happier for it.
You could always upgrade down the line, and then that 1hp motor would be perfect for a disc sanding setup.
 
My motor is 2hp and I have to be careful as I can stall it if I really get after it. This normaly happens with really large flat grinds and belts that are getting warn out. I think the big difference you will notice is when flat grinding with a platen the increased friction on the back can really load up. I will say I'm happy with 2HP but if it was 3HP it would be better. Saying that, If I was building a new grinder a 1hp motor would not even be considered. But if I had it laying around I would turn it into a disk grinder. But after saying all that if it's all that was available then I would make do with it but I would not like it.
