I just finished running all the dust collection piping for my home shop. I now need to ground the system. I know I can run a bare gound wire though the piping but I heard somewhere that you can also drive a screw through the duct every few inches, leaving the body of the screw protruding into the duct a fraction of an inch. I guess you would then connect a wire to each screw and to the tool. Does any body out there have experience with this method or could you provide a link for more information or a source for a kit to do this? Thanks alot!

Might do better with this topic over at Knots.
I would just
run a bare copper wire thru the pipe and connect it to the chassis of the machine.
I think what I'd do is run bare copper through the pipe, but thread it in and out of small holes along each length, so that the wire is pulled tight against the side of the pipe and isn't apt to contribute to blockage. You can wire each pipe length separately before connecting them together, then tie the wires to a master wire externally.
To the best of my knowledge the ground wire does not need to be inside the ductwork. I'm assuming you are working with 'plastic' pipe. The main element is that the pieces of equipment be 'grounded' with respect to the dust collector. There are factions that say grounding isn't necessary, but I would definitely do so.
