<p class=MsoNormal><font size=2 color=navy face=Arial><span style='font-size:
10.0pt;font-family:Arial;color:navy'>I remove hammers glued on with hide glue
with dry heat all the time—both old and new. I also see glue joint
failure between soundboards and ribs glued with hide glue
frequently. I’ve not seen that with Titebond. In fact,
for the most part, the glue seems stronger than the wood. While you may
be able to soften Titebond with heat, I wouldn’t worry it about for most
applications. Glue joints in pianos are not generally subjected to the
kind of direct heat you mention and if they were I don’t think I would
trust any glue to hold up. </span></font></p>

style='font-size:12.0pt'>Titebond isn't forever, try this experiment for your
self, glue a junk hammer onto a shank w/Titebond and allow it to cure for
24 hours. Put a heat gun on it for less than 30 seconds and it will come free,
put it under a brooder lamp, with a 100 watt light bulb in it, with the shade
right down on top of it for a few minutes and again it will come free. Dry heat
will cause Aliphatic resin glues to soften after they have cured, try the same
thing with a hide glued hammer, it will remain tight. In order to remove/soften
hide glue you must have a humid heat or as we call it steam. </span></font></p>
