Are you sure it's a soft v-bar?  How much material did the stringer take
off?  Is it possible he actually filed through the hardened section?  =
How
long and what is the angle of the counterbearing section?  Is the
counterbearing area flat or sloped?  Can you manage to insert something =
to
increase the deflection angle and shorten and detune the segment?  You =
might
experiment by inserting a cut piece of brass half round or half oval
underneath this section to see if that doesn't help.  Have you looked at =
the
v bar with a mirror to examine its shape?  I would certainly try that =
before
considering torching the v bar. =20

Did the rebuilder file it correctly?

Paul Revenko-Jones has a fine class on this. Maybe he could send you his
handout sheets.

You might also try moving the strike point on those notes.

Howdy,

=20

Back to the 8' Seiler grand.  Sorry if I'm starting to sound like a =
broken
record.  Here's the story:  I serviced this piano when it was new.  Not =
long
into its life, it developed a noisy duplex at the low end of the treble
section.  I muted it off.  I tuned it for a few years, I moved away...

=20

I moved back.  In the meantime, the piano was restrung.  I started =
servicing
it again a year after it was delivered.  9 months into servicing it, the
noisy duplex returned in the exact same spot--but add another note.  I
freaked out (not in front of the customer), the customer freaked out, =
too
(not in front of me).  I contacted the rebuilder who said he filed the =
capo.
He and I came to the conclusion (whether we are correct or not) that it =
is a
case of soft cast iron.  I looked up hardening cast iron in the =
archives.
To do that would mean taking the plate out of the piano and that's not =
an
option.  I'm convinced if I refile the capo, the same thing is going to
happen again. =20

=20

I know there are some pianos that have some sort of rod installed at the
v-bar.  Is it possible to do the same with this piano at the capo?  Has
anyone done it?  Do you have detailed instructions?  Will someone hold =
my
hand?.....Please?

=20

Thanks,
