OK, so I figured when I formalize my dust collection for the home shop
I'll just go to Grizzly and order all the metal pipe, fittings and
blast gates I need. Going all metal I'll avoid the static problems.
Going with smooth pipe I avoid the friction loss of flex, yada, yada.
Well even with a very conservitive 2 branch run it is a bit costly.

So if I go plastic and religiously run the copper wire, etc. can I
just use standard ABS or something of the sort?

Oh, boy, here we go again. :-)

General consensus here is that the grounding wire is not necessary. Google
Groups search will turn up hundreds of posts here on the subject.

Being a safety nut I'll probably do it. I have seen it detailed so
specifically in the Grizzly and other help docs. But I can be
convinced with science so maybe I'll research that while I look around
for answers about using pvc or abs.

Thanks for the reminder.
