#$^"# Grinder!! -- I'm getting shocked.

...it looks like we just hijacked the helloutta this thread. Sorry guys..back to the topic.

Damn kids!!:D
 
I havn't had any static problems with the Wilton square wheel grinder with the DC variable speed controller, but I sure as heck get static build-up on the Buffer. The buffer zaps me more when the humidity is low in winter time. In summer it doesn't do this when the humidity is up.
 
I get zapped by my grinder when my stomach makes contact with the worktable mounting rod, through my tee shirt. I wear leather gloves when I grind, so the fingers do not get zapped. As long as I keep my distance, I do not get shocked. But, I know that most folks grind barehanded so wearing leather work gloves is out of the question.
 
I don't ever get zapped. My floor is concrete in one side of my shop and wood in the other. All my machinery is on wooden work benches. I have two grounding rods, one on each end of the building, both six foot in the ground. I don't use any mats. I also like Glenfiddich Scotch, so that may have something to do with it.
 
What I constructed last winter was a belt clip and a 2.5' piece of braided copper wire. I put a refrigerator magnet with a hook on it on the end. There is a 1meg resistor in the middle of the wire. I clip the belt clip on my belt and stick the magnet on the base plate. It works for the buffer,too. When I move away it just pulls off and goes with me. The resistor prevents possible shock hazard from accidental AC contact (At least,any more than the normal danger). I also got an anti static mat, but the belt clip ground strap totally stopped the lightning bolts.

Stacy,

This is an excellent idea. The magnet is what was missing in my thinking. I will make a few of these up, one for myself and send some to knifemaker friends.

Thanks for the post
 
The clothes static spray stuff works great. Just spray the inside of the moving belt for a second or two. The belt will stay static free even if put aside for a bit of time. I've posted this many times . There are many that beluieve it won't work because it's so simple but it dores every time unless your motor is shorted out. Frank
 
This is helpful, thanks guys. I've been living with this too, just trained myself not to jump when I get sparked (like my dog). I managed to convince myself that the arc is so pretty it was worth it. :D But I think I'll try grounding myself now.

Thanks for the post Frank. I will give this a try. I can tell by the number of post, that this is a very real problem in the shop.
