The buzz is more likely from a rib separation under the crack than from =
the
crack itself.  I wouldn't glue in the card stock as I would be surprised =
if
it created a permanent band-aid fix.  It probably stopped buzzing =
because
the card, for the moment, restricted movement of the panel over the
separated rib.  I would check again and then consider a repair pulling =
the
panel back to the rib.

Good Morning All,

=20

Yesterday I called on a lady with a nice old Knabe Upright.  During the
inspection phase of the service I found a few buzzes when certain bass
strings were played.  Further inspection revealed the buzzes were =
emanating
from soundboard cracks.  YIKES!  She had been hearing them, too, and =
they
were annoying her.  I fixed those buzzes on the spot by folding a couple =
of
business cards and inserting them into the cracks.  I told her that once =
I
practiced doing soundboard shim repairs on a couple of "guinea pigs" in =
my
garage, I'd contact her about doing the repairs the right way.  She's
interested in having them done.

I made the decision to do the band-aid in the meantime like that because =
I
know she plays the piano often, and she lives alone, and it was so out =
of
tune!  I just didn't want to turn around and leave by dismissing the =
piano
until the repairs could be done.

=20

What I'd like to ask those of you with more experience is this: did I =
put
the piano at any further risk by doing this "McGyver" type quick-fix in =
the
short term?  It didn't seem like it could aggravate the problem, really, =
and
that the main downside would be that the cards were susceptible to =
vibrating
out again....  should I have put a drop of Tite-bond on them?  Should I =
NOT
have done this for some reason?

=20

Thanks,
