How does a Coote run on various HP?

Hello. I am fantasizing about getting a Coote, and wondering how they work w/various motor sizes. Right now I have a 1/2hp, that I would like to hook up so I could at least use the thing, and then upgrade my motor. It seems like I read a post somewhere about someone doing that. My question is, are they rather anemic even at the 1hp level, or would it work like my 1/2hp 4x36 but w/ a handier design?
Also, are there real good reasons for getting the 72" over the 48" other than the standard belt size?
Thanks for any replys.
 
Since I use a 2hp motor with my 10" Coote, I can't say how it will be on just 1/2 a hp. I would have thought that it would be pretty weak, going by what a lot of folk say about having a 1/2-3/4hp per inch of belt width. I am pretty happy with how mine moves steel. I have used some other people's home built grinders that had either too little motor, or too small a drive wheel and found it easier to use files :p

Longer belts should run cooler and work out relatively cheaper in the long run. You are paying for the belt material, plus the joining process. One join per belt whatever its length.

Best of luck

You'll probably be able to stop the coote easily on a 1/2HP motor. I'm sure it will run, but you'll have a tough time if you grind hard. It'll be slow going. A cheapo 1 or 2hp motor can probably be had for less than $50, it won't be tefc and might not last as long but it would be an ok start.

The reason to get the 72" belts is because of the standard size, which translates into better pricing and more belt options. You want to try to keep your tools from limiting your knifemaking. 48" belts will get hot and break down faster too, so you'll be paying more per grind even if they are half the price of 72" belts.
 
Any Cal,
I am a newbie knife maker...I bought a Coote in June of this year and started grinding about 20 blades out of 1095. Well, they are back from HT and I am putting handles on them. I have a One HP motor hooked to my Coote - It doesn't cut it (at all.) I will be upgrading to at least a 1.5 (hopefully more) in the near future. I would go to 3 HP or more if I had 220 in my garage. You waste a lot of time when you bog down the motor then have to wait for it to spin back up to no load speed for your next grind. Good luck
 
I use a Coote with a 1 hp motor and I have never bogged it down, it works great. I grind a lot of D2 and 52100--pretty hard on equipment. It is very important to have the machine mounted in a secure manner with the motor/pulleys aligned correctly.
 
I'm using a coote with a 1hp. Right now I am grinding .250 1084. so I am hogging off a lot of material. It takes me 20 to 30 minutes to rough grind a 4 to 5 inch blade. (at 1750 rpm)
