Wapin Bridge

[Tim Coates]

Hi Dave,

I sometimes follow threads on Pianotech through the
archives.  I subscribed just to fill in a few gaps with your answer
about my brother's piano.

I made the piano sound as good as time would allow beforehand (tune,
regulate, voice).  The hammers were filed before the Wapin Bridge
installation.  That is my standard procedure when doing an hands-on
seminar.   After the strings had settled down the next day I checked for
open strings.   Nothing fancy done here, just
basics that a good technician would do.  As usual, some of the "Killer
Octave" was a little too strong after the Wapin installation, so
the chopstick was used to correct it.

There will be a new page on our website dedicated to the truly
scientific in the near future.  Bob Coleman (Jim Coleman
Sr.'s brother) has been doing research for us.  His findings will be
located on the new page.  Bob Coleman wants to help further Wapin
Bridges, as he is a true believer.  Bob hears and knows there is a
positive difference when a Wapin Bridge is installed.  He is not being
paid for an endorsement and approached us about the Wapin Bridge.  He is
a retired
NASA scientist in the area of audio waves.  My understanding is he
developed and implemented the use of audio waves to determine if
anything had been damaged on the Space Shuttle after a flight. He worked
with
Dr. Earl Kent in the 1960's studying pianos.   In the near future you
will
be able to see a picture of Bob Coleman with Dr. Earl Kent  at NASA
doing an experiment on a piano.

By the way, Wapin Co., LLP will be sharing a double booth in the
convention hall at Chicago with Stanwood Touch Designs.  We will be
showing Michael Wathen's home piano.  It is a Baldwin C with Wapin
Bridges, Geers soundboard, Stanwood action, and Sanderson bass
strings/string scale.   It was on display at Arlington.

Oh Dave,  Dakota Territory is now North Dakota and South Dakota (as
of 1889).   Is Texas still a separate country? <g>
