Testing for the ultimate adhesive

[tmickley]

After 1 cycle of heat at one hours at 150F, then freezing, then heat for 1 hour at 175, then freezing, we have two more failures tonight.
The 3M spray adhesive (held out way longer than I ever thought it could) and the rubberized super glue. I think the rubberized super glue holds better at room temp, at freezer temp it seemed to be quite a bit harder at freezer temp and it just seemed to 'shatter off' when tapped. The tap is 3 solid whacks with the big hammer on the edge of the wood trying to shear it off the metal. The remaining adhesives are holding much better than I thought they would with the whacks they are getting. I'm going to do one more heat, freeze and whack cycle and then move on to some other kind of destructive test.
