Oops, typo.  Should be a very WEAK solution.  Maybe two or three little
Drano crystals in a quart of water.  Mind you, this is all untested theory,
but the chemistry says it should work.
 
Susan:  The Elmer's could be interfering with the cyanoacrylate
polymerization in a good way.  (Sorry, sometimes I get carried away and
forget that not everyone uses "normal" words the same way we chemists do!)
I think Elmer's is from an organic source (still horses?) which the CA would
"stick" to, and could make the bond stronger than a homogenous CA polymer
due to increased branching and interlocking of the molecules.  My question
(perhaps because I have as yet zero experience with CA in piano
applications) is "Why do you need a "super-glue" accelerator?"  Every time
I've used it, it bonds very quickly on it's own.
