Dust collector and static electricity

[Barefoot1]

I have found that when I have my dust collector attached to my planer or drum sander that I frequently get a shock when picking up my wood from the out feed side. I can feel the charge coming off the hose when I get my arm near it. Is there some way to alleviate this?

I Remember seeing something on how to ground dust collector hose. I post it if I can find it. If I remember right it's not much more than running a coper wire thro the hose system.

Heavy copper wire run through the hose and then to ground. It will stop clog ups and let the vacuum do it's job.

Barefoot : I brought a small roll of copper wire, now this is real fine copper wire now, and wraped it around the hose clamp and then around the hose and then tightened clamp ,and then ran it to the nearest grounded Plug in and it worked just fine for me !!!! This is the one that go's to the wood planer . No shocks yet !!! I'm no expert , but this was the way I was told to do it .Marshall

OK, that makes sense, I'll make a trip to Lowes later today and get some wire.

You want something like this:

Yeah, I saw that this morning. I am just confused about whether you run the wire through the tube or wrap it around the outside, and then do you ground it to the tool or to the dust collector or both?

I run 2 cyclone dust collectors and to start I ran multi strand copper wire on the inside of all my hose. it was hooked up to the collector body and every machine. I got fed up with the wire catching pieces of wood from the larger machines and did a lot more research on the web. I found the majority of wood shops do not run the wire on the inside or outside of the hose.
So I tore all my wire off and just make sure each machine is well grounded.

Most of the articles that I have read about it says to run the wire on the outside of the hoses and plastic pipe and then run it to ground. My understanding is that you just need to wrap it about once every two or three feet along the length of the pipe. Most of the plastic hoses on collection systems have wire in them for stiffening the hose, I would think that you could attach a copper wire to that wire and ground them that way. I have not done it yet and I know that I should. When I am using my dust collection hose to vaccum up the sawdust from the floor and I brush up against one of me tools I do get quite a shock from all of the static that has built up in the hose.

I wonder if the climate has anything to do with the shock you guys are getting. I live by the ocean and while we don't get a very high humidity like some places, we are not a dry climate. The only shock I got is from 1 belt sander that I have since grounded better.
