I am making an add-on table top (14" x 24") for my drill press and was gluing a piece of masonite on top of a 3/4" ply substrate using TB III.
Even though TB III claims to have a a longer open time, it was a challenge to get glue spread on both surfaces and get it all clamped up. I was using a putty knife and a glue brush to spread glue - and trying not to be too messy. Fortunately I had the cauls and clamps all laid out and ready to go. It was a cool day, don't now if I would have made it had it been 90*.
What's the secret to getting a relatively large area spread with glue before it sets? Work faster, don't worry about the mess?
