Subject: A challenge for CA glue.


>THE PIANO:
>A donated no name baby grand, years ago extremely heavily doped with
>Garfield's ( pools of brown sticky stuff that has hardened), - no pin
>bushings, most pins would need vast improvement to come up to zero pin
torque.
>( You know, - they jump 5 notes flat when you release the tuning hammer)
>
>THE SITUATION:
>Little old ladies club, their big yearly scholarship fundraising event is
in 5
>days with a "singing group" coming in do a program, "PLEASE - PLEASE, do
what
>you can." My work basically pro-bono. (I occasionally do some.)
>
>THE PLAN:
>A great piano to experiment with! What's to lose?  I intend to try putting
CA
>glue (thin- medium- thick ?) into the pin wells where the bushings should
have
>been, letting it set up and then tuning.  The piano was previously  tapped
>about as far as it can go. I will remove the action and shield the key bed,
>etc.  It would be very difficult to turn this piano over to treat the
bottom
>of the pinblock due to its location and my feeble back.
>
>REQUESTING YOUR HELP:
>I wish I knew this was coming up, for I would try water thin epoxy, but no
>time to get that now. I would like to know how thick the CA should be, how
>many grams or ounces might be needed, waiting times,  - ANYTHING that would
>help.  Also, IS THIS LIKELY TO WORK? - I will report to the list, because
if
>CA works in this piano it should work anywhere. Is the CA likely to work as
>well as an epoxy treatment? For this much CA glue the fumes will be
awesome.
>Anything to do there besides ventilation? Should I drop a drop of water
into
>the holes after the CA glue? - What about accelerators?
>
>Please feel free to e-mail me directly, but I will be anxiously watching
the
>list. If it doesn't work right away I would still have  time to burn down
the
>building and save the ladies from grievous embarrassment.
