Many years ago, I worked for Tiffany & Co. The polishing of silver and the static it produced, gave many polishers a good jolt and set many a dust collector on fire. The only way we could somewhat control static was to run #4 bare copper through the pipes, dust hoods and bond everything in the area. On dry and cold days we still would get static discharges. we had to attach a ground wire with a clip lead.
