I am in the process of taking apart a 20 foot section of my 6" metal dust collection piping to my cyclone. It was clogged to my cnc machine. I suspect that the wire running inside of the plastic sections, ie the drop and connection point caused the problem collecting the larger particles or strands and starting the clog. I was wanting to reduce the size to 4" s&d plastic piping for more suction power at the cnc. Instead of running the grounding wire inside I was thinking on running it on the outside of the pipe, using pop-rivets to hold it on the pipe. I was thinking of running the rivets every 6 inches or so, having the tip of the rivet exposed inside the pipe to act as a receiver for any static electric and being connected via the wire on the outside back to the cyclone. I hope I am making some sense and for those with more electrical knowledge than me, wondering if this would work or if not why not?
TIA
