Hi David,

Well, I'm not sure if the capo hardness was ever right since the problem =
was there before it was restrung, also.  The problem didn't surface =
until the piano was a year old or so.  Then it took about the same =
amount of time for the problem to surface after it was restrung.  It was =
the repetition of the timing and the symptoms that got my attention.

Thanks for the suggestions of inserting the brass half round or half =
oval.  I will try that.  BTW, what sort of establishment would carry =
those?

  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,



  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...



  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



  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?



  Thanks,



  Barbara Richmond, RPT
