Hey guys so these are the previous threads that probably make this one relevant:

BSI vs G-Flex Opinions - https://www.bladeforums.com/threads/epoxy-show-down-2019.1643465/

BSI vs G-Flex Testing - https://www.bladeforums.com/threads/west-system-g-flex-vs-bob-smith-mid-cure-testing.1650348/


Combat Abrasives sent me some Rogue Epoxy with my 3''x79'' belt order (for my SGA). I decided to test it against G-Flex.

I performed 3 "test":
  1. Drop Test (This one wasn't terribly successful... the micarta busted before the epoxy could)
  2. Metal To Metal Bolt Test (Good results here)
  3. Micarta to Steel "Salt Pellet Pour Test" (I'm going to trademark that name....)

 
It sounds like either epoxy will work, but no reason to change from G-flex for sure. I really like the way G-Flex bonded some of the micarta to metal so the micarta broke rather than epoxy bond.

Good stuff, and your test looks very valid. Of course, any serious tests requires anywhere from 3 to 5 samples of each test to see what the spread is. That's my ONLY issue with the test, only one one sample tested.

Good work.
 
Awesome work as always, love your videos, shot so well and everything is smooth (no crazy audio spikes, etc).

I kind of follow in line with Ken - no reason to switch, and I don’t think either outperforms what should be the norm standard so to speak. Pretty cool to see CA perform so well vs the gold standard.

The area I’m always curious about is how they hold up over time and vs adverse conditions. I want to make a lasting product - I’d hope no one ever does anything like the above documented video to the epoxy bonds I put on my knives ;)
 
You make good videos, thanks.

Do some tests with the epoxies with the materials fastened with mechanical fasteners and see if any of the epoxies fail.

This is real world use for knifemakers.

If you can stop the initial movement, of material, with mechanical fasteners such as Corby bolts, PEENED pins, Loveless bolts the strength of the epoxy really does not have to be the strongest.

Heck with mechanical fasteners you do not even need epoxy for strength but rather as a barrier from corrosion getting between the materials.
 
nice video, but I agree with AVigil AVigil about a practical test for knifemakers.
if you decide to do that, I'll send you what I use, which is Golfworks epoxy, and I believe a higher lap shear strength and less costly.
 
Hey guys, thanks for the feed-back. Next time around I'll tailor my test to your suggestions. Although, I have a good deal of both of these epoxies to go though before trying out any new ones!

Good, now get some handle material and fasteners and run the tests again with the same epoxies:D
