Read the recent comments about removing glue from clamps. Another way to handle the situation is to save all your old aluminum foil. Cut it in strips about 2 inches wide and the length of your project to be glued. Fold them over the clamp bars so that the excess glue is on the aluminum foil and not the clamps. I do this all the time. Possibly not practical for huge projects but works perfect for making butcher blocks, trivet’s, and similar size projects.
