  The real world ...

  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.

  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.

  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.=20
    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)
