Static electricity can build up in plastic dust-collection ducting if that energy can't dissipate via a ground wire. After installing a PVC-pipe system, I considered doing what many have done: wrap a grounded copper wire around the piping. Then a much simpler solution popped into my head.

I wrapped aluminum duct tape, barber-pole-style, around the ducting and hooked it to the grounded screw holding the faceplate of an electrical outlet. Problem solved, quickly and inexpensively. Before getting started, narrow the tape by cutting its roll in half; doing that makes the tape easier to wrap and makes it go twice as far.
