[pianotech] Tight tuning pins

[Greg Newell]

Clearly I am mistaken about the properties of resorcinol glue. I stand
corrected. Thank you for the correction!

Greg,

I had been led to believe that resorcinol glue was a very good expensive
glue. Our store sold Sohmer pianos for the last 25 years of their NY
production. The Sohmer brothers extolled its use and had it throughout the
piano. They praised its use because of its waterproof and strength abilitys.
I know their tuning pins were very tight, but they were tunable. One can see
the dark color of the glue in the layers of the quater sawn pin block. Looks
a bit like the new Gorilla glues. Is the problem really the glue or under
drilling of the pins --- or both?

I wonder if backing them out will create more heat which would make the
resorcinol gummy. Depending on how long you wait (seconds, minutes, hours)
to put the pins back in and whether or not the pins are already contaminated
with the same resorcinol you might recreate the same problem. Just a
thought.

Regarding the recent discussion about dealing with tight tuning pins when a
piano has been restrung with oversize pins, can anyone speak to the efficacy
of backing out the pins with a drill and then pounding them back in on an
original condition Baldwin grand from the 80's with that stupid
Resorcinol-laden pinblock?  (Same problem, pins very tight and jumpy, lots
of cracking noises.)  I'm thinking this technique is at least worth a try on
one that I have that is a particular problem.
