DaveL - You're welcome. I'm glad someone else is getting a kick out of this work.
OK I re-attached three pieces - just grind - no wash. DEVCON, JBWELD, Gorrila
Then I took it on a plane trip. 2 flights 4 hours each in luggage (you guess the temp and pressure - but I don't think it's any different than the cabin). Then a trip thru the dishwasher.
Then the IMPACT Bar test
Bar test video - 700K
The DEVCON came off on the second impact. E-120HP came off too, but it was set after cleaning with Simple Green - so that's a nontest. However even after several BANGS! these remained:
Loctite Xtreme (wash with simple green)
Loctite U-05fl (wash with simple green)
JB Weld (no wash)
Gorilla Glue (no wash)
I need to start over so I took to pounding the blocks off the steel. Oh baby
Xtreme came off, but it took more than a few good wacks - pretty darned good for not being a 2part adhesive.
U-05FL stayed on longer and took more hits
Gorilla Glue took several whacks the the dymond wood did a lot of chipping before it came off.
The winner was JB Weld:
As you can see it never came off. The dymond wood is coming apart before the JBWeld gives up.
To the left is the Gorilla Glue sample, to the right is DEVCON.
Because of the simple green problem the only results I can confirm at this point is:
DEVCON doesn't hold real well after the dishwasher/plane flight
Gorrilla Glue holds really well
JB Weld glue seam on steel is stronger than dymond wood.
