And if you do what solutions have you have you come up w/? Thanks Ed The humidity helps a lot w/static electricity Ed. And because of a lot of wet areas ground rods get hammered into the ground at spots close to water. Our clay is real conductive so the ground rods are effective. In Florida the sand in not conductive so the code requires 3 ground rods at each location and/or connecting to the re-bar in the footings. If you have a wet grinding area it is a great idea to hammer a ground rod in at your grinding station and take a tap off your motor ground and hook it to it. Helps carry the electricity straight to ground instead of sterilizing you

He has to be intense, he's using a MAC, so has to focus! Bet he wouldn't know how to tumble rocks, tho'. Or how to use a flat lap. Cats are pretty much useless, when it come to lapidary work .

For padding in a big tumbler. That would be totally cruel. Not funny. Please forgive Speaking of, this Mac never gives any flack. Happy w/it. I think it has a turbo in it, the disc goes ZIIIIINC, and it's updated. DON'T spill coffee on the keyboard or it goes in the round file.

makes a lot sense about the static electricity and humidity, James soon I'll have to use a grounding strap on my small motors The Foredom spindle & scissors sharpener...

When a dry front blows in static is common. Most common in winter. Rarely during hot season. Never really thought about static since it is not so common here. I suppose it is in the dry desert though. Maybe rock dust would stick to you from static. Why do you need to ground the Foredom spindle ?

James: These are the 2 grinders that give me the most static….mostly I didn’t mean to imply that my ¼ h.p. motors (saw & Lortone) shock me. They don’t. But these 2 machines during the dry winter months produce a heck of static electrical shock whilst buffing or sharpening--- buffing mostly. It’s a lousy picture! I should taken the lampshade off my head and used it as sunlight reflector Ha Ha Included in the picture is the cheapo anti- static wrist strap. It works great! Its cordon the ’twice as sharp’ w/an alligator clipped on left hand wheel. If you can see that? I might invest or make my own better one in the future. Also in that he picture is the scissor attachment and the diamond wheel standing up. It fabulous. That attachment hold scissors blades at the correct angle whilst sharpening across the wheel. The diamond wheel is used for hairdresser scissors so it they don’t get the metal hot. I use aluminum oxide wheels for other scissors like Wiss upholstery shears. I’ve incorporated the attachment and diamond wheel in grinding the center binding joints in the rock’n heart. I can get a good flat 90 degree flat, a straight grind and clean efficient cut with that diamond. Still experimenting….

Problem solved. Never thought about the buffing wheel. Holy cow, that one could really crank out static. Dry season worse, hmmm. And you guys get some really dry air. I sharpen on a scissors sharpener, all the Norwegian brand w/the orange plastic handles, uh, Fiskars. we cut dirty sandy plants w/them and dull the heck out of them. my scissors sharpener is crappy though. Nothing like the rig you have. I understand not getting the metal hot. It softens them. Sweet rig for sure. You got the grind goin on Ed. I wondered how you ground that joint w/out getting chips in the rocking hearts. Must be fine grit and dead flat wheel. Do ya remember when Detroit used to put the antistatic straps out the back of cars in the 70's/80's:

Wow No James that's interesting about the anti static for trucks what was it purpose?
Interesting about the cutting sandy plants Fiskar are a good shear. Maybe to good for that operation although lots of florist use them
but I would think a pair of Wiss upholstery shears would hold up better I assume your looking for a good clean cut on the stem of the plant?

The roots are like cutting electrical wire. They can be really tough like bamboo. The reason we like the Fiskars is the big handles. They prevent blisters. We divide the plants with the scissors and the roots are still muddy and sandy. so it is real hard on the blades. Many times they break at the pivot hole. the stainless steel is glass hard and will snap. Man that is some hard steel.

The beltsander I sometimes use (mounted on a workbench, not handheld )has a tendency to shock as well. And yes, especially when the humidity is low. I remember attaching an alligator clip (AKA, roach clip) to a three foot or so length of wire (about 16 gauge, I think), clipping it to my waistband and letting the other end drop to the ground. Result - grounded butt, end of zapping! Simple fix.

Yep my 1x42 vertical belt sander is another machine zapper sometimes when I buff the hair on my arms stand on end really a strange phenomenon James you need a pair Wiss shears just because your a cut'n grind'n dude if I come by used pair I'll keep you in mind but they are hard to find people keep their Wiss's

I hate to use a Wiss for the abuse. The bearings in the scissors wear out too. From the sand getting in the bushing. It is a bad way to treat a pair of scissors. Soil full of rocks too. They are useless dull. This is my crappy scissors sharpener: Try putting the clips from ear lobe to ear lobe Jean, or battery cables. That will connect the cerebrums.

A couple of large marbles. Two inches and 1.5 inches across. One of unakite and the other obsidian. Diamond sintering finally broken in and grinding smoother. Using 7 inch Harbor Freight wheel.

Those "marbles" are pretty frickin' impressive. The time that this could save in sphere making is - noted for future projects.

Tried to collect flat agate pebbles on the Rio Grande so that they could be broken down easier for tumbling captbob. The round ones were not easy to break so they were passed by. But they would shape up quick for spheres. Was thinking about two turrets?(maybe wrong word) like a 2 cup sphere machine that could pinch the rock from each side of the rock. That would allow the rock to rotate. Mounted on a swing so that it could swing down on the diamond cup. Kind of like a lathe some how. Unclamp it from the cups and rotate it 90 degrees, re-clamp and grind again. just brain storming...

How loud is grinding with your creation? Just wondering how much the neighbors are gonna hate me.
hold on, I think your video had sound... off to check.
****
yeah.
I think I'll be doing any grinding of the side of the house closest to the neighbors with the yappy little dogs.
You're using a 7" wheel now? Like it better than the 4? Starting over - with no wheels on hand - what would you buy?
