The time needed to glue up wood in a cold workshop may be twice as long as in one at room temperature. Below certain levels, cold temperatures can weaken joint strength because the glue can't form a continuous film as it dries. If too cold, the glue may not work at all. For yellow aliphatic glues the minimum temp is about 40 degrees F.; for white polyvinyl acetate glues it's about 55.
You can attach a length of soft copper tubing to extend the reach of a blow gun nozzle used with an air compressor. The extra length will allow you to clean out motors and interior machine parts without getting a face full of dust. The end of the tubing can be bent to reach around the back side of motors or into other hard-to-reach areas. Use a wet/dry vac along with the blow gun to help keep dust out of the shop.
