bridge pin placement

[Richard Strang]

In my short 7 years of experience, I have found at least one string with a
false beat in every single piano I have tuned. I even bought a tool from
Schaff to help the situation. I just rub it back and forth on the string to
kind of heat it up, and the beat goes away.....sometimes. Not all the time.
Rust is a factor here. Any rusted string can have false beats that will
drive you up the wall as a piano tuner. The customer won't like how it
sounds either. Maybe that's why she/he called in the first place.
   I don't think the problem is in grands anymore than it is in uprights. I
say that, because the vast majority of the pianos I see are uprights and
they all have strings with false beats. Most of the false beats are still
there when I'm done, too. Sometimes the false beat of the outside string
will kind of cancel the false beat of the center string. Yes, sometimes
there are that many. Anyway, I try my best, and I use my little tool once in
a while. Just my two cents.

Regards,
Richard

That will put a nice dent in the bridge top and only be a temporary fix at
best.  Better to tap down the bridge pin itself and/or secure with a pit of
thin CA.
