[pianotech] Center Pin Zapper

[Ken & Pat Gerler]

Gregor,
The Zapper using the door bell transformer assembly only takes a few seconds to apply the tweezers to the ends of the flange pin. Depending on your "success", the flange pins on an upright - whippen, hammer and jack - can be accomplished in half an hour, much faster than repining.  The biggest "slow down" factor is the tweezers getting to hot to hold if you go "non-stop".  Ask how I know.

  I never heard of that idea of a zapper and it sounds really weired to me. How long does it take, I mean how long do you zapp one center pin? Would it not be easier, quicker and more long lasting to replace that pin?
