1. Gluing Temperatures: I bought your chess board download (WoodWorks Episode 411), and I am ready to glue the edge pieces. It's my understanding that plastic resin glue needs to be used at 70°+. Since it needs to remain in the clamps "overnight," does the temperature need to be 70°+ all night? How cold can it be allowed to get while in the clamps?

I have had great success using a $50 electric oil radiator heater to keep glue-ups warm in the shop. I take two saw horses and tarp them with a roll of 4 mil plastic. I place the glue up inside with the heater (leave a few feet of space around the heater) and put a thermometer in there to check the temperature.
