I just purchased a dust collection system and in the manual it says to stop
static you need to ground it. I have read in different books about grounding
the pipe also. Can someone point me in the right direction on how this is
suppose to be done?
Gus, Steve, and Homer are experts and will be glad to help you...if
they aren't too busy arguing about what the meaning of "is" is.

Or you could ignore it. It won't explode.
Grounding insulated plastic pipe is a PITA. Forget it.
You can run an internal ground strap, but it achieves little, snags
shavings, and the dust will wear through it in time.
If you really have static problems, run an external ground wire and
ground the metal components of the plumbing. Ungrounded these will act
like capacitors and build up a much worse charge than the insulating
If you absolutely _must_ avoid static, switch to conductive plastic or
metal for your DC. But you don't need to.
Hi Rob Tork ! Do we know each other ?
(and if we do, where do you fit a DC into a caravan ?)
In a plastics factory - you have to go back that far in the process,
even before the moulding stage - you can't change one to the other.
Basically you just fill the plastic with carbon powder. It's a lousy
conductor, but it's enough to remove static. Look at the packaging for
electronic components. If a plastic is anti-static conductive, it'll
Or pink. The newer antistatic stuff I've been receiving is pink. The foam
has a slight "soapy" greasy feel.
There IS a way around the static issue on synthetic materials:
I was having a problem with static electricity buildup in my office a few
years ago. When I watched a nice fat spark jump from my screwdriver to a
microprocessor board I was working on ... well, let's just say I wasn't
happy. Killed the board.
I did something few are willing to do ... I thought about the problem,
including taking an inventory of on-hand materials that would help me.
I ended up mixing up a solution of liquid fabric softener and water (1 part
fabric softener to 4 parts water) and put the mixture into a spray bottle. I
sprayed the entire carpet with this solution and let it dry.
Static problem resolved.
I did have to re-apply the solution the next year ... but haven't had any
problems since. I'm now enjoying my 4th static-free winter.
Now, for those ready to pound their keyboards because I'm talking about
carpet, not PVC ducting ... hold on. If you take the same mixture and spray
the outside of the DC ducting, you will give all those little electrons a
happy place to travel, rather than herding them up in bunches. No shock,
because no charge buildup. No charge buildup because you gave the electrons
a path to follow.
For the black pepper sorters out there ... it really doesn't matter what
fabric softener you use. Remember that most fabric softeners advertise their
ability to "reduce static cling". My wife had a bottle of "Snuggles" in the
laundry room, so I used it. Some people may not like the perfume added to
the fabric softener ... choose one without the perfume.
Now, go into your shop and make some stuff!
(for those interested, I replaced the defective surface mounted IC that
popped on the microprocessor board, and it lived happily ever after.)

Yup. Except that many have done that exact thought process years and years
ago. That has been a pretty common treatment of static prone carpteted
areas for at least 20 years. Not perfect, but effective.
