soundboard split

Actually I have witnessed dead notes at the end of the tenor bridge
caused by bridge/soundboard separation, and it was pretty localized. I
fixed it on the spot with CA glue, spraying accelerator first, then
pushing on the bridge with a screw driver while running the glue along
the base. That was two years ago and it is still holding.

Brian,
 
Since no-one else has answered, I'll throw in my 2 cents.  These notes
are wound bi-chords?  If that's the case, I would first eliminate the
strings themselves as the cause.  There are methods of restoring some
life to old wound strings.  For example, remove the string, form a loop
in one end, and rol the loop up and down the length of the string.  Or
just measure them and buy replacements.   For $20 or $30 you'll know for
sure.  I doubt very much that any soundboard damage would cause such a
specifically localised problem.
 
Mike

Hello List,
 
My 1965 Wurlitzer baby grand has a couple of "dead" notes at the inside
edge at the bass strut.in other words the last 2 notes before the
strut/bass section.
 
I have tried "juicing" them..and using a hammer iron.  Neither one
worked.
 
I then seated the strings at the bridge pins.  Nothing.
However, while tapping the strings I noticed a crack in the soundboard
that seems to follow under the bridge except for at the very end..close
to where the dead notes terminate.
 
Are there other things that I can try to eliminate the "deadness" before
trying to fill the crack.  Is the crack even an issue?  It seems to be,
but I am looking for other ideas before tackling filling the crack.
 
I can't even see it from the bottom side because of a wooden support in
the "nose" of the piano.
Does anyone have any ideas of how I should proceed?
