Thanks for the public service announcement.<br>
<br>
</font></font>Yes<font color="navy" face="Comic Sans MS, sans-serif" size="2">, yes the Evil Glue indeed. We should collectively write up a piano glue policy handbook.<br>
My two favorite <u>Do not use </u>statements are.<br>
1. Do not use, Epoxy to glue in a sound board. The only way to clean the rim is with a 1 1/8 inch Makita hand held belt sand or pneumatic gringing device of some kind. I actually know who did it. He still breathes. :) and No, it wasn't me.<br>
Please use....Cold hide or hot hide glue. Tight bonds which are aliphatic resins of various iterations(see Franklins data sheets), Bolducs PVA mystery glue or many wood working PVA's (Read data sheets)<br>
2 . Do not use PVCE on felt work. Especially key bushings. <br>
Think reversible. Hide Glue is first for so many things that are going to be redone.<br>
Please use hot or cold hide glue<br>
My two cents<br>

I'm doing a belly job on a piano that was sort of rebuilt once before.
The abused agraffes I posted earlier came from this piano too, as did
the mystery plate finish that proved to be way more problematic than it
should have been.
Today's rant is on glue choice - again. I continually find some random
glue from Hell that I wouldn't even have in the shop arbitrarily used
for piano work. The issue this time was getting felt off the bottom of
the damper guide rail. This lowest of all technical requirement
refelting resisted all Q&D efforts at scraping and chiseling. I didn't
try heat, because by then I was already miffed at wasting unnecessary
time on something this dumb already, so I took it back to the belt
sander I'd used to take the mystery stain and "patina" off the rest of
the guide rails. Pictured, is the result. A perfectly good and usable
belt rendered into trash, and it still took considerable time to melt
the stuff off with the immediately ruined belt. People, please think
about your choice of glues for piano work. There are choices available
that will work at least as well as the Gonzo Craft Glue and Termite
Repellent you for some untelligible reason actually purchased and used
in pianos, that are more rationally dealt with by the next guy. If
you're making permanent changes, by all means epoxy the sucker in, but
refelting the underside of the damper guide rails? Jeez, Cosmo, some
signs of intelligent life please.
I haven't yet gotten to stripping off the dampers, but I expect to find
the same Name on Request Acky Pucky used there, and can hardly wait.
Now, thanks in advance (and hopeful avoidance), but I already know about
soaking, boiling, heat application with a heat gun or iron (hot
meteorite, etc), surfactants like alcohol, detergent, and the ever
popular wallpaper remover, so I'm not looking for a list of
recommendations for dealing with something you can't see and are
guessing about. What I'm hoping against all hope for is that at least
someone somewhere out there will read this and miraculously rethink his
choice of glues for stuff like this. Hot hide is, naturally, the first
choice. Second would be something else that dries hard so can be easily
scraped off, like the Titebond molding and trim glue, Assembly 65, or
Bolduc. PVCE does NOT qualify. Give the next guy some consideration,
since he probably won't know who you are or where you live and can't
hunt you down and feed you the ruined sanding belt. Since he likely
can't extract vengeance on you, leave him pleasantly surprised. It's
only reasonable, honorable, and fair.
