Ah, that's interesting. I thought the pattern looked familiar, I just couldn't place it. I never would have guessed flooring...
Also I wasn't sure how it was being attached which is why I asked. I didn't know if you could just use an epoxy or if it would need something special with a mechanical fastener to help retain the grip material.
Yeah, it's typical to use some kind of mechanical fastening, pins, etc. But depending on the material, like rubber, it can flex and absorb shock and bending. Hard handle material like wood and micarta will put tremendous stress on the epoxy and cause it to crack if there is no mechanical fastening under the same conditions. The fasteners will take the brunt of the stress keeping the epoxy from debonding.
The problem with pinning a rubber handle is that if the pins are flush with the surface then as the rubber flexes and compresses in your hand you will feel the pins protruding and create hot spots and will be uncomfortable. You have to countersink the pins or fasteners. But this leaves less material for the pins or fasteners to hold onto. The other option is to use rubber pins. But these are not really any stronger then the adhesive itself. So I'm trying out just adhesive alone to see how it holds up
I've tried super glue in the past for rubber and it works ok but eventually splits from being too brittle. The E6000 will remain flexible but harden up enough to create a strong bond. At least that's the theory
