Hello,

I'm new to all of this so please direct me to the correct thread if this has already been answered.

I'm getting ready to start making my first knife. This will be the "cheapskate" way, using a hand drill and files. However, since I do enjoy making things, I'm starting to research the topic of belt grinders.

Has anyone used a bench grinder as the power source for a Coote type belt grinder? If not, why not? Not enough power? Or impractical because of location of items?

I'm saving my pennies and trying to figure out how to get quality gear and still afford to eat. ;)

Any help is greatly appreciated.

A bench grinder in my opinion would be a last resort. It runs too fast and you will have trouble holding a pulley on it, most grinders don't have a key. Gib
 
A 1 HP motor running 1750 is cheap enough to obtain, almost as cheap as a bench grinder.

Check out some flea markets, and also find an electrical motor repair shop in your area, and ask them if they have any used stuff.

I paid $35 for a 1HP Baldor with a fresh rebuild, from a motor repair shop, so I know you can find them.

Good luck.

You can also check water pump reparator. I bought some
3/4hp or 1hp used motor at good price...

But for my Coote grinder I bought a new variable speed motor (1hp)
with a controller... Variable speed are a must !!!

If possible, find a 1hp motor minimum... 1.5 hp or 2 hp are better...

Good luck !

I really like my new Coote 2 X 72.

As stated above:

Find a 1725 RPM motor (NOT 3450 RPM) - 1 HP and if you find a 1 1/2 or 2 HP at a good price get that one. Get a set of step pulleys so you can vary the speed. Norman Coote sells a set at a reasonable price. The ones I got from him are not balanced. You can pay a bit more and get balanced pulleys from KMG (I'm going to- but the pulleys I got from Coote are quite functional and work just fine).

Later you can go with electronic variable speed when the bucks are there.

If you have enough bucks to start with a 2 X 72 now do it. I, and I understand a lot of others, started with a 1 X 30. Great experience I never wish to return to.

Everyone,

Thanks for the great replies. I will start looking around for a rebuilt motor at a good price.

Until then, I'll post pick's of my first attempt using the cheapskate method. :D

Cheers!

I wouldn't get anything less than 1 1/2 horse. I did try a 1 horse bench grinder for my old Cootes when my 2 horse burnt up but couldn't stand it. Way to fast and no power.....Ray
