[pianotech] CA glue vs. PinTite or Garfield's

[ben at benspianotuning.com]

It seems to me that just about everyone on the list that has responded favors CA glue over a glycerin-based pin tightener (or at least use the two in conjunction). Let me give you the link to an article I found in the archives on the issue of proprietal chemical composition of pinblock tighteners: http://www.player-care.com/pintite.html. 

I checked the PTG membership roster and I'm pretty sure that the author of this article isn't member right now. The article looks like it was written at least 10 years ago. It'd be nice to get a hold of this technician and get his opinion, since he advocates PinTite as an acceptable non-glycerin treatment.

If you are treating the block due to lack of funds to repin, then a rethink 
is necessary.
Glycerin continues to attract moisture.
That ends up causing the wood to 'rot', then the pinblock has to be 
replaced.
With the C/A, in theory, you could ream the hole for a bigger pin.

I have used CA only once and do not plan on using it again. As Mr.
Foote mentioned the feel is different between CA treatment and
Garfield’s. I prefer the Garfield feel. With the CA there was no
“spring” left in the pin. And with poor rendering due to rust, which
can be expected on a piano that needs the treatment anyway, I had to
resort to flagpoling the pins in order to render the strings and the
result was not as stable as I would have liked. Both types of
treatment will make a piano tunable, but Garfield’s does not have the
odor. One change I have made in the application is to rinse the coils
with denatured alcohol after application to make sure that there is no
glycerin left to attract moisture and promote rust on the strings.
