1.FASTEN THE GROUNDING BAR

TO THE BODY OF YOUR INSTRUMENT

The grounding bar is used by electricians to ground house circuit wires. It comes in various lengths and can be found in most local hardware stores or build-er/contractor supply centers. The empty slots ( 2, 3, or more) come drilled all the way through — this is where fasteners can be used to attach the bar to something. But you may need to drill through if your slots aren’t in the perfect places.

To anchor the grounding bar, simply make 3 holes with a hand drill into the surface you’ve chosen to be the body of the instrument. The screws shown in the bottom photo are hex head 10-32 machine screws (smaller and different types of machine screws could be used) secured with T-nuts, speed nuts, or standard nuts with lock washers and fender washers. If screwing into metal, you can use a tap to thread the holes.

If you’re going to mount the bar on wood or thin metal such as a tin can, you may need only a hammer and nail to make the 3 holes. With wood, just use wood screws or something similar. Nails alone might possibly do the job with a bit of wood glue — start the holes with a nail, and add a bit of glue to the holes before driving them firmly. Heavy-duty epoxy, riveting, welding, or even slotting a surface with a milling machine or router are some other ways to anchor the bar.
