loose loose tuning pins

Dean,

Yes, I used thin. I think I had one from Schaff (never again - it hardened
in a couple weeks) and one from the local hobby shop.

The amount used was 2 oz, but could have been more. It's been 2-3 years ago.
I put in CA until it "pooled up" at the top of the hole. After it had time
to seep in, I did another application. Then a third application from the top
side.

Did not use accelerator.

I did a tuning immediately after and another 1 1/2 years later.

There are a handful of pins that were worse, but nearly all were loose.
However, you could make the piano sound better, though I don't know how long
the tuning lasted.

Blessings to you as well.

  John,



  Some questions



  I presume you used thin variety that was not old.

  When you say a lot, how much in oz?

  What brand did you use?

  Did you use accelerator?

  How much time did you allow to elapse before you tried it?

  Have you been back for a follow up to see if there is any improvement?

  Was it only a handful of pins that continued to cause problems?



  I have never encountered a piano as you describe that did not show major
improvement after treatment. In fact one grand that was particularly bad in
my early days of doing this, I applied top and bottom with 4-6 oz as you
describe. The pins grew so tight you could barely turn them, but it took a
few days. When you apply a lot of glue it takes a few days for it to fully
cure.



  Blessings

  Dean

  Julia,



  I've had a piano that did not respond to two treatments. It holds barely,
but not well enough for fine tuning. In fact, on this small grand, I had
tipped the piano upside down to apply a LOT of CA to the underside of the
block. It was disappointing to find out that when the piano was upright
again it hadn't worked, although another application from the top helped a
tiny bit.



  I always tell the customer that CA might not work.



  Repinning is needed when you have loose pins, and there is enough money to
pay your labor. :-) But, always educate the customer about rebuilding and
better performance the piano will have.



  You can keep the old wire when restringing, but it's just as easy to
replace with new.

  Greetings.

               How tight can CA glue make really loose tuning pins? Is there
a limitation to it's effectiveness. I would think if they are really loose,
(so loose that you can actually see a tuning hammer ride back as fast as the
sweep second hand of a watch!) that maybe 4 treatments on those pins might
do the trick, but I don't know. Any suggestions? What sanctions a repinning
job? If one does re-pin a piano must all the strings be replaced with new
ones or can you re-string the old back on?
