Apparently a lot more to this than I had ever considered.

#2When I built my new shop, I put in one of Bill's cyclones piped with 6" pvc.
It's nice to work in a clean shop.

No, Ralph. You can't ground PVC pipe since it's an insulator rather than a conductor. Grounding only works on metal pipe.
My tools are all grounded. and the DC only runs when a machine is in actual use so there's no build-up of a static charge as happens in commercial settings where the extractor system runs continuously.

@Ralph Lipeles,
Yeah, you can't "ground" an insulator, but with PVC pipe you could run wires inside and outside the pipe to ground. And/or use ionized air. It's used during the manufacture of PVC pipe where static charges can be dangerous.
