I ordered a Beaumont KMG-PL

I have been saving a little bit hear and there. then my friend gave me a 1hp motor which speed up my order process. Now I just have to wait for it to get here.

Ohhh you lucky bastage.... I thought I was shitting in high cotton when I got my Grizzly.

But a square wheel grinder is the tits....

Take good care of her.

Ps: Remember that grinders feed on human flesh.

Looks awsome.

A couple things about the pictures: Is there anything on the drive wheel to keep it from slipping? it looks like bare metal. Also, I'd run the belts counter clockwise, opposite from the way the yellow belt is shown.

The platten setup looks pretty nice. It would be easy to make others if you wanted. I've been thinking of making some curved ones to do some not-so-slack grinding.

Russ, I paid $650 for just the grinder no motor. Here is a price list of the different configs.

The nice thing is you can modify this any way you want, use what ever motor you want. Although I am sure other motors work better then some.

Hal, The Grizzly is actually made about 50 miles from my house. I'll take pictures once I get it all set up.

Jacob, I am not sure about it being a problem with slippage. I know a couple people on this board have one and when I was asking didn't say anything about that being a problem. Good eye on the yellow belt. I didn't even realize it was going clockwise. I just knew that it should be counter clock wise because I have used my friends. If you do make the curved platten post some pictures please.

Thanks
Martin

I just built my own belt grinder using wheels I got from Beaumont. It's absolutely perfect for my needs. I'll post some pictures when I get home for lunch.

That would be great.

Here is a picture of the one I just built. I got the drive and idler wheels from Beaumont Metalworks and the contact wheel from somewhere else. I recommend getting the contact wheel from him too. This one uses 2"x48" belts. I would have liked to go to the 60" belts but I was a little short on space so I stuck with the shorter betls. I used a 1HP 3450 RPM motor, giving me roughly 3600 surface feet per minute. It can really rip through the metal.

Thanks Jurgen.

If you ever feel like posting pics from other angles, I would gladly name my next kid after you.

Your vacuum setup looks nice too.

Thanks

Here are two more images: One from the other side and a closup of the pivot for the upright. The contact wheel is a 4" contact wheel, the drive wheel is also a 4" wheel. The top idler wheel is a 2". The dust collection is really nice. I"ve got it set up so the suction turns on whenever I turn on the equipment and shuts off when I"m not using it. All I have to do is remember to use the blast gates to set which machine I"m working on.

The only thing I've noticed about this belt grinder is that it does generate a bit of static. I get a small static discharge whenever I ground myself after using it.

I have the same static problem (only much worse) with my el cheapo Delta belt sander. The solution is to get a piece of wire, or a computer wrist band static guard, and attach it to your body and then ground it on a metal piece of the sander. This will keep you and the grinder at the same zero potential. Just make sure that the wire isn't connected in such a way that it could get fouled in the sander belt.

Jurgen,
How did you set it up so the suction starts and stops with the grinder?

Thanks

It's at times like these when I wish I wasn't a mechanical idiot. That looks SO SIMPLE(tm), yet I know I have zero chance of successfully building it on my own.

Heck, Monday was the first time in my life I even used a router...

There are these power strips that have a "master" outlet. When there is enough current draw through the master outlet, the power strip turns on the rest of its outlets. The vaccum goes on one of the switched outlets.

Here is a link to the one I got.
http://www.bitsltd.net/smartstrip/speclcg34.htm

The only thing to watch out for is that the strip is limited to 15 amps total. I had to have one of the switched outlets engage a relay connected to another wall outlet to turn on the vaccum. Between the grinder and the vaccum it is a bit over 20 amps.

The static isn't a big problem. I could also probably get rid of it by having a static "pickup" brush on the belt that was grounded. Any grinder with a rubber contact wheel will generate some static electricity. After all, it is basically a Van de Graf generator.
