To save your skin, could you use "alligator skin", or leather finger tips?

Yes Pat.It is the best way.Leather for grip especially.It may be expensive,that thing goes thru leather real quick,though.Small stuff is the problem for gloves and fingers.I have developed a feel and special skin:>And it will shatter thin materials because of the speed.For tumbling materials it is hard to beat though.

It is the standard threaded attachment Diane.I believe it it 5/8 UNC(unified coarse thread?)So,on the grinder is a 'end of a bolt' and the diamond wheel is a 5/8 hole basically.I believe JSGEMS can hook you up w/an adapter to slow the too fast speed down by putting it on the end of a motor.If that was turning at 800-1200 and had 100 and 200 grit i would be making cabs

James, I bought one of those Harbor Freight cup grinders when you posted the low price here a while back. My driveway has not been dry very often lately because of snow, but I got out there and used it once. I have a Makita grinder and I'm not sure what speed it's turning at, but it chipped the stones sometimes. I think the gaps in the wheel contribute to that. It sure works fast though. I can't wait to try it on some Petoskey stones this summer, I think it will work great on them. I built a jig to hold my grinder and made a crude shield from the trash can of a shredder than stopped working. It's not waterproof, but should stop most of the water from hitting the grinder. I haven't figured out how to drip or spray water onto it yet though. I hadn't thought of simply dipping and grinding. Does that keep the dust down pretty well? Attachments:

Rob, did anyone tell you electricity and water don't mix? Now maybe if it was one of those 18 volt battery operated ones... I know, recharging batteries gets tedious. Jean

Yep, it worries me a lot. That's probably why I haven't actually applied any water yet!

Dip and grind is very effective with this device.I always look like i got a bra own when i am done due to the mud streak across my chest.It turns so fast the water is slung off using the dip nd gring method.But the dip and grind is essentially dust free.Chipping is a problem at high speeds.My angle grinder runs at 3600.The other one is 10,000 and it really chips stone. Would be great if it turned 600-1200
PS Rob,try your rig up on the end so that the cup is horizontal.I like it better that way

I know that streak when I grinding carbide for saw blades side grinding...mostly we used a spray misters an air compressed small tank that held the coolant and a really nice flexed hosed nozzle for precise coolant spay
anyway I'd had a Zoro streak across the chest from it
those spray misters are really nice I should look into it for rock grinding I haven't seen them in years

I fell down laughing because of the way you express yourself Ed.The Zorro comment-mostly... That dip and grind is very effective in stopping the dust but does create a Zorro streak that Tide has a hard time removing.I can see the contact point real well and the water never comes close to getting to the motor because of the sling factor.
