I just received this information from someone who used to work at Electro String Corporation:
"The problem you had is due to the type of cutter used to thread the "U" shaped chassis.
The machine shop that threads this piece needs to use a thread forming tap... not a standard tap.
This will give a far superior thread cut and won't cause the screw to wobble or even strip itself out.
You can have the stripped chassis retapped with a 6/32 thread screw ... that would make it still usable. And appear to be stock.
Tapping by hand is NOT the way to do this .. it needs to be done on a mill with a slow rpm setting and forward/reverse capabilities."
