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.
