Great idea! I wish the set screws had fine teeth to bite the wire. I think all grubs stainless should have them. That might be best for not pinching the wires off. ThanksI found 2 strips of old credit card under the coil while you are tightening it made it much easier to hold the wire in the right place, keep the rod in the coil, hold the ends of the wire down and tighten.
