Hot Hide Glue Problem

[David Love]

Not that I know of, but Titebond does sell a slower cure glue.  It's not as
thick as the trim glue but if you dig a well in the end grain of scrap block
of wood and use that for your glue reservoir, it will suck some of the
moisture out of it and thicken it up a bit.  Whether you will lose the slow
cure properties that way, I don't know.

My hammer hanging isn't the fastest and I found the trim glue to set up just
a wee bit fast for me...can it be slowed down like hide glue?
