Step 9Other Emphases
This is an example of the grounding bar used on unusual materials but in a conventional way.
The tines are spring steel and uniform across the span.
The body is aluminum, a 3/4 inch thick block, and there is an aluminum shim.
I wanted to make something sleek that looks machined but I really just used a cheap, much abused drill press. I used a tap to thread the anchor screw holes, putting the tap in the drill press and turning the chuck by hand.
Surprisingly, the thing is so heavy that a hollow door on sawhorses makes a good resonator for the instrument.
