[pianotech] Old upright

[Dean May]

CA is real easy to try and cheap. For maximum penetration, move the pin back
and forth while you put a few drops at the base

This is a case of me wanting to tell the client to burn the piano and look
for something better, BUT, it has a lot of sentimental value.  And there is
really no way of telling 100% if the pinblock is cracked, unless I destring
and remove the plate, is that right?

Hmm, well I can tell you what's NOT a good idea and that's the metal tuning
pin "sleeves" sold for the purpose by suppliers!  Using larger pins might
work, as might sandpaper shim or veneer shim. But it partly depends on
what's going on in the pinblock. If there is a crack thrugh several layers
of lamination, for example, that's causing a line of pins to be slack, using
shims may only force the crack wider.  CA might be a good idea. an easy fix
if it works. Can be done without putting the piano on its back, but maybe
not feasible if coils touching bushing.

 

Best regards,

 

David.
