(was soundboard repair) Titebond and hammer twist

[Annie Grieshop]

At the KC Convention, in ___________'s class (I really don't remember right
now), I heard the statement made that hammers glued with Titebond will
eventually twist out of their original alignment due to moisture changes as
the glue dries completely, if I recall correctly.

This is not to argue with Mr. M. but to ask about that statement:  did I
understand it correctly, and have other had that experience?  Personally, I
have noticed new hammers glued with Titebond seem to not be in the same
alignment after several months, but I had chalked it up to my poor memory or
poor technique.  But if it really is a consequence of the adhesive, then
that's very interesting (and makes me feel better).

Now that I've got a reliable glue pot, it's no longer an issue, but I'd
still like to know about Titebond and twisting.  Thanks!

        I used a program from a previous function in the hall to pour out a
puddle of Titebond then removed all of the hammers I'd marked and cleaned
the old glue from the shank hole. I then did the same with the shanks then
using my now tacky Titebond re-glued them. Several of the holes were much
larger than the shanks so the tacky glue helped to fill the gap nicely. The
gaps in over half were too large for CA, even the thick CA to have filled, I
fear.

        I have talked with others who seem shocked that I don't use it(CA)
more but it isn't reversible and it sets too fast in many cases, no working
time. I don't get things in perfect alignment everytime, first time!
Apparantly there are those who are perfect out there or they are willing to
settle for good enough in the interest of saving a few minutes, I know not
which. I just know when I reach for my glue bottle it's the one that says
Titebond 90% of the time.
