I've tried what must be about every brand and type of 2-part epoxy glue on the market. Most all do a pretty good job until you get to having to pull the arrows out of really tough type targets and you have fixed broadheads on. I've only had one completely pull out over the years, but have had several where the insert has pulled out about 1/8 on an inch. Then for whatever reason, you can't pull it out the rest of the way unless you replace the broadhead with an old field tip, then clamp the field tip in a bench vice and heat the tip slightly until the glue gets warm and you can pull the shaft off the insert. Has anybody used the non-clear epoxy formulas? Tonight I used JB Weld to glue a coupe in to see how it works. I rough up the inside of the shaft and clean with alcohol and do the same with the insert too. That's not my problem. What I'm finding is that the epoxy hasn't hardened up like it is supposed to have. I'm really careful when mixing to make sure I get equal amounts also. Let me know if you have anything that really works good. Thanks!!
