Wapin bridge

[Delwin D Fandrich]

Early on we planned on doing this very thing. However, we were told it
wouldn't work that way and the whole bridge had to be done at one time. I
don't recall what explanation was given, but to my mind (weak though it may
be), if the Wapin idea was going to make a difference in performance that
difference should show up in this kind of test. I could not, and still can
not, conceive of any reason why not having the Wapin bridge pin
configuration on one unison should adversely affect the adjacent unison
having it.

In the end we set the project aside and didn't proceed with any installation
of the Wapin. The piano we had intended to use for the experiment was
subsequently remanufactured according to our own standard procedures and
sold to a very happy customer.

Del.
