Chalk temp of TB III is 47=C2=B0. It's best to warm the boards, significan=

Additionally, and I don't know for sure, but I work with the rationale that=
lower temps require longer clamp times, before releasing the clamps.

When I bring in frozen and weather exposed boards (I know yours probably
aren't) they're usually quite wet. This is often surface moisture, but
can penetrate 1/4" or more. I'm not sure I'd trust a glue joint in that
kind of situation.

They usually warm up quite quickly, though. An hour or two seems to be
good, so why risk it?
