LOL. That might be why he told me to call on Monday to double check.

Tractor supply is also a great source for continous duty motors, I picked up one a few months ago.

Hi, I am fairly new at all this, but I bought a used Highland park grinding/trimsaw unit last summer and it needed a motor. I went to Home depot and bought a swamp cooler motor. It works great! You can even get a two speed one if you want to slow it down. I use the slower speed for the polishing wheel. You just need to wire up 2 switches for the 2 speeds. I got a 3/4 horse one and I think the RPM's are about what you need too.
I also got one of these for my 14" slab saw. Works great also!
These run about less than $100.00 to $140.00. The more horses the higher the price.
I use it outside on the porch and the motor will get a little hot in the summer heat. (I am in Arizona) So I just work for a while and then shut it down til it cools. In the fall it was fine all day.
Hope this helps.

Yeah - my dad suggested a swamp cooler motor as well. Unfortunately, I can't find them up here, lol. He was going to price them for me down in NM, as I'm headed that way in a month anyway. I'm checking Tractor Supply tomorrow to see what they have as well.
Thanks!

Okay, a comment in another thread made me wonder if I was possibly under-powering my future grinder. I know the saw specifically mentioned a 1/3 hp motor, and my first grinder used a 1/4hp motor. But the GP-8, which is basically a new version of what I have, uses a 1/2hp motor. Should I look for a more powerful motor? And if so, would this be a good one: www.amazon.com/1725RPM-56Frame-Furnace-AO-Smith/dp/B000LE7G66/ref=sr_1_4?ie=UTF8&s=hi&qid=1264803686&sr=1-4It's ODP instead of TEFC, but that shouldn't be a problem for the grinder.

A little more power is better than not enough power.

Me again. So, what's the difference between Farm Duty and regular motors besides the price increase?

Farm duty motors are as close to undestructable a motor can be made. They are totally enclosed, have heavy duty bearings, more winding, higher duty rating, basically better everything. They are actually worth the extra price. They are farmer proof, LOL! Woody

They certainly looked solid! Finding the right combination there was difficult. No 1/3 hp, no 1/2 hp in 1750 RPMs (they had one in 1025 that would probably work for the saw, though).

Google Dayton electric motors...they have lots of different motors for a variety of applications. When the motor went out on my old rotory tumbler, I got a great replacement from them..it's normally an HVAC motor, but it fit the bill perfectly and wasn't expensive at all...
