[pianotech] self tuning piano

Paul said: "Wim:
Apparently, the current is sent thru the bottom of the tuning pins, then
through the wires, and grounded at the agraffes/capo bars. Current through
the wires heats them up and changes the pitch. The tuning pins will heat
slightly, but not enough to harm the block. Practically, they won't heat at
all since the pins are so large."

Paul,
Say What???!!! A basic knowledge of wood, would dispute that. I'd rethink
that, for sure. This guy's been around too long and has never proven his
theory to anyone's satisfaction. (let alone a WORKING prototype) Typical
Engineer Type.....living in a dream world, that us mortals really can't
imagine.<G>
That's my take on that,
Joe
