CA glue

[David Graham]

I would be very interested in hearing from anyone who has used CA
glue to render an otherwise untunable piano usable again. I have several
private customers with well-used blocks in their pianos, for whom
rebuilding is not really an option. Does this work on a previously doped
block? Are those old uprights really salvageable after all? Is there any
advantage to removing the tuning pins or should they be left in place? I
remember there was a thread about this awhile back, but don't remember
if this was conjecture or fact. What affect does the climate have on a
block with CA as a filler? Does anyone have any idea about the longevity
of this repair?
As a for instance, I have a client with an open face block in a 1920's
Bosendorfer.  She is quite elderly, but plays the piano every day. She
simply refuses to be without the piano while it is being rebuilt. The piano
actually sounds very good except in the low bass (dead) and the high
treble (no hammerfelt). Could I twist the bass strings, replace the action
and then use this technique to help the tuning pins hold? If it lasted
several years it would be worth it to her, because she may not last that
long, and she would still have "her" piano in usable condition.
