The remaining samples didn't care how many times I dropped them down a tube, 12" to the concrete. It created a nice little jolt.
So the survivers right now are:
Loctite Xtreme
U-05FL
E-120HP
Acraglas

Just for fun I cleaned off the bar where the failures where with a 50 grit belt. Then I re-abraded the samples with a 36 grit. Then re-glued Devcon, JB Weld, and Gorilla Glue.
But I didn't do ANY washing. No simple green, no brake cleaner. I just want to see if the cleaners where part of the problem.

PS For anyone else that has had failures. Did the epoxy stick mostly to the handle material or the steel?
All of mine leave the steel clean.
