Yep, I see it here, and I'm glad to not be the only one getting shocked. :)

Cash got bit quite a few times on his take manifold. So, you weren't the only one. I'm not sure why this new cabinet bites that way, but it certainly does.

Glad no big zaps and good work backtracking/fixing the problem! |
Yes, it is ironic when you think of it that way. But, as in most things, having the right grounds made a huge difference.

Dust collection systems with plastic piping or housings are notorious for static problems.
While silica is not flammable, atomized aluminum definitely is explosive and red iron oxide is a burn rate catalyst. Im used to sawdust collection, and the recommendation is to use metal duct or at the very least a bare ground wire continuous inside the duct. Dust in the duct creates charge by friction just like an old fashion hard rubber hair comb. |
What a revolting situation... [get the humor?]

On the other had, I did make progress on another front. I've recently had other folks over using the blast cabinet, and they complained of getting a significant electrical jolt from time to time. And, as I was using the cabinet today I noticed the same thing. In fact, since I was aware it might happen I was thinking about it, which probably made it worse. :-hair Given that, I started thinking about what could cause such a buildup of jolts. Chris and I'd tried a jumper from ground to the cabinet, but that didn't really seem to make much difference. However, a little investigation determined that the dust collector wasn't grounded. So I grounded it and that helped. But, there was still a pretty significant jolt every so often - and then I realized that I wasn't grounded. :-X19 I then made a loop in the end of a jumper, clipped the other end to a ground, slipped my little finger through the loop, and put the hand into the glove. And, that did it! No more jolts. :-jammin And, I always thought that you and Chris [Cash, too] were well grounded individuals!!! }> |
Jim - I can see how a wire though the pipe would drain off static instead of letting it build up and then arcing at the dust collector. I will try that. Thanks.
David - I get the revolting picture. ;) I don't know about Cash nor Chris, but when using my blast cabinet I'm now quite well grounded. I was apprehensive when I put that loop around my finger as I didn't know if I was going to get a serious jolt. But not a single jolt has gotten me so far as the ground appears to bleed the static off before it can build up. |
Got back from the powder coating plant. All the brackets are powder coated except the new AC brackets, I am waiting on them to arrive. So I will be installing the brackets and parts they hold tonight. Engine compartment is really looking good. Will try to post pictures after completion.

Gary, im surprised you don't have one of those ESD wrist bands you could clip to the chassis, instead of a wire on your finger.
I guess the rubber gloves are very good insulators. |
Jim - Glad you brought that up as I've been thinking about it. The wire loop is working perfectly as I've not been shocked while using it. But, I've been wondering how else I could solve the problem, and the wrist band is one of the possibilities. However, it looks like it would be more "fiddly" than the wire loop, and it doesn't look as durable.
What I've been hoping to find is a conductive glove to which I could attach a ground wire and somehow glue it inside the rubber gloves. But, I've not found that kind of glove. Meanwhile I'm still using the wire loop - quite successfully. All - I need some help. Today I was media blasting and powder coating several parts for the rear suspension and realized that I'm missing a nut. It is to the bolt that holds the front of the rear spring to the frame, and looks like the one shown below. It is a 14 x 2.0 mm nut, and goes with the bolt shown below the nut, and the bolt is ~5" long. But, my bolt is a bit deformed on the end, so I could also use a replacement bolt as well as the nut. :-wink https://cimg9.ibsrv.net/gimg/www.for...5e993af816.jpg https://cimg7.ibsrv.net/gimg/www.for...d38047a762.jpg https://cimg8.ibsrv.net/gimg/www.for...a695b233f7.jpg |
Chainmaille cutproof glove from a kitchen catalog? :D
Amazon lists a couple of electrostatic discharge gloves. https://www.amazon.com/s/?ie=UTF8&ke...l_932yuadhai_e |
Hadn't thought of chainmail, but those things are 'spensive! Amazon has one for ~$100. As for the ESD gloves, none of them seem like the type to tie a wire to. Maybe I could, but.....

What about something like this? https://www.amazon.com/dp/B00O0Q12ZW?psc=1

Changed the oil today. I'll be putting some miles on Friday, it's quail season!

At this point I'm happy with the wire going over my little finger. It isn't high-tech and looks kinda odd, but it sure works well. I've easily spent 8 hours this week blasting after I put the wire on and I've not gotten shocked once. So, I think I'll stick with it for a while. But, if y'all have more suggestions keep them coming. Who knows, maybe someone will find "it". |
