I have an all-plastic Craftsman shop vac, connected to a plastic dust separator. They share a movable cart. I take a plastic hose from the dust separator and attach it the the tool in use. The hoses are those black plastic "accordion" hoses. On dry days, I can see the sawdust fingers around the hose that is plugged into the tool. (In case you are thinking about leaving a wire touching the ground, I operate my tools mostly on paving stones set in sand on hard dirt, but I work on the concrete slab in the garage on rare occasions.)
Here is my question:
-> How would you ground the hoses, the dust separator, and the shop vac? There is nothing but plastic, plastic, plastic on the outside of this contraption. My goal is to prevent static discharge between the "final" hose and the tool itself.
