[pianotech] Build a Zapper

[Ryan Sowers]

There is more to it than just removing moisture. It may have that effect but
it also seems to iron the felt.

> voila moisture removed. Of course if the flange/bushing/pin happened to be
> in a humid environment it didn't last very long.
> As we discovered, the removal of said moisture is temporary(no one asked if
> it was successful, just how to build one) and when the moisture returns the
> initial problem is still there.
> Proving, as with most "quick fixes" it looked better on the drawing
> board than in actual practice.
