The real world ...
=20
Tuned a little console today, not bad for a Wurly and really pretty =
clean in
the treble, except for one absurdly wild string. Ran the old "beat
eliminator" down to the bridge and the beat, mostly, went away.
=20
Also tuned and older Hamilton studio. Treble just grossly obnoxious. =
Took a
peek at the bridge. It looks like most of the pins have risen about =
halfway
out of their holes, standing about 1/8" to 1/4" higher than the bridge =
top!
There was no one there (rural church) to authorize any repairs and I was =
out
of time anyway, but I'd like to lay that puppy down and epoxy in some
slightly longer and/or thicker pins just to see if the results are worth =
the
trouble.
=20
By the way, I once removed a thundering herd of wild beats from a little
Francis Bacon (gblerk, pfff) grand this way. If anyone wants the beats I
took out, I can ship immediately. But right now I'm filling out a legal
form, donating my nostrils to science.

Hello Ron N and Listers
I sent this yesterday:
Hello Ron (and List)
Your statement about false beats is a "must read" for all interested in=20
tuning pianos. I concur with all you have said. It all makes profound =
sense.

I now eagerly await a "trial by fire". I have therefore put your obiter=20
dictum on the List for all to read.
Now....
Today I have had the opportunity to test your statement about loose =
bridge
pins =3D false strings. I took a screw driver to a false string in the =
D5 zone
where there was a particularly obnoctious falseness (piano: baby grand
Hopkinson) and... it worked!  The beat disappeared as I touched the pin =
on
the speaking/string side. Remove screw driver and the falseness =
reappears.
OK. The owner knows the bridge is split at several pins (not where I was
experiencing that Nossaman Phenomenon though) and he accepts the high =
cost
factor of replacing the capping. So, I rest your case.
Regards
Michael G.(UK)
