Guess I've gotten complacent about glue-up times with Titebond. I glued
melamine to melamine (using Roo Glue) and thought clamping for 90
minutes would be long enough that I could do a little more work on the
assembly. NOT! I ran it through the TS once to bevel an edge on the
other end of the work piece, and the moment I finished, the two Roo
Glue'd pieces fell apart. The glue was completely WET. I gotta start
paying more attention.

Earlier, I forgot to raise the Delta mobile base wheel on the TS, before
cutting the melamine. I didn't ruin it, but I was caught off guard by
the sudden pivoting movement of the Unisaw and silently thanked the
powers that be that there wasn't a whopper of a kickback. What ELSE
could I have screwed up if I didn't adhere to a "no beer before
operating equipment" policy?? I'm dangerous enough without alcohol!

Sigh...

FWIW, Roo Glue won't dry in 4 hours either. (I'm talking
melamine-to-melamine here; melamine to mdf dries quickly) DAMHIKT. It
will dry pretty well in approx 15 hours, however...

Perhaps the non porous surface prevents the glue from curing much like the
bottle it comes from.

oh, definitely! I usually glue mdf to melamine (dado or rabbets) where
one surface of mdf can absorb the moisture. The bottle says it's ok to
use it for melamine to melamine also. Just takes FOREVER to dry. It's
tenacious as hell, once dry, on mdf-to-melamine joints.

I tried prying the pieces apart this morning; no luck (which is actually
"good" luck).
