Thread: BELT SANDER/ BUFFER STATIC SHOCK - OMG

We used to get this literally every day polishing dental tools on the buffers at my former employer. Ended up getting the polishers those anti-static wristbands. Never had any of them catch in the machines, yes it's possible I suppose, but if you are working in the correct manner your wrist should be nowhere near the wheels and even if it did catch, the cord attaches to the wristband with a quick snap detach so it wouldn't drag your hand toward the wheel. Simply position the cord on the underside of your wrist and it's out the way of any danger. I would absolutely recommend them.

Here is how I resolved the problem for three bucks!

Several online responses to self-grounding static with buffers and grinder/belt sanders is to attach a fan pull chain to a shoe, your body or clothing with an alligator clip that drags on the ground.

The chain is weak enough to break easily or pull from the connector if caught up.

I bought a 3-foot length of pull chain and a couple alligator clips for about $3. The chain fits into the wire holder in the alligator clip and the connector is a bit wider and does not allow the chain end to fall through.

For me 3ft of chain allows me to clip to the bottom of my pants pocket and the flexible chain drags on the ground about two inches with no trip hazard. This is enough to ground and discharge me when walking around the shop.

I hook the chain to the on and off toggle switch of the buffer when not in use. Literally takes a few seconds to clip it on or remove it.

No more shocks.

so its just clamped on your pants and not to any skin?

I put a dragging chain on my shop vac. Killed the static

Yup, I figured if clamped to a shoe works or Joseph’s steel toed boots. The chain was sold in 3ft package it just happened to be the perfect length to clip to my pocket.

I was buffing for a couple hours yesterday and no shock, but when it tried it without the chain, I got zapped.

So, took your advice Dave, with the extra clip and a few inches of chain, clipped it to one of the support fins at the wheel allowing it to drag on the floor.

BTW, I just picked up this sweet, Stainless DeWalt 10-gallon shop vacuum on sale at Lowe’s for $89.

Comes with a heavy-duty wire re-enforced hose, bunch of attachments, great handle and nice smooth rolling rubber wheels. Has more suction than my old ShopVac with a larger plastic can and much noisier motor. This one is much quitter and at a great price.

Correction, I paid $50 for the DeWalt vacuum, on sale and $89 for a 6-gallon Craftsman pancake compressor. also on sale.

I went in looking for a new compact compressor and saw the vacuum on sale. My 10+ year old ShopVac was making the death whine. I have oiled the bushings s couple times, but it has sucked up a ton of dust and has more than earned it’s keep. So $50 buck for a upgrade replacement, no brainer.

Love the new compressor also, my old one was a 5-gallon upright tank that took up a super small footprint and also 10-15 years old. I use mostly to blow off stuff daily and occasionally run a pin nailer and air brush.

BTW a couple years ago I upgraded my air hose quick connect to Milton’s. OMG worth the $25 upgrade. On the new compressor they have held air for 48-hours at 100PSI. I hate air leaks, buy the Milton’s for no leak air hoses.
