I actually 'invented' this method long ago (probably others before me
:-) ) but decided it might wear the board eventually being metal on
metal and all.
I've developed a better way. I'll have material that should be
optimal here soon to just put a whole new contact face on that is made
of the same type of material. I'm having a special run done that is
thin enough to fit the gap reliably. I've tested some stock material
and it worked but I'm afraid bass might vibrate it and cause spurious
triggering. -Bob - Sounddoctorin.com
