Yes! I used a bore brush on the inside of the shafts, sandpaper on the HIT inserts, and cleaned everything thoroughly with acetone. I've tried Easton epoxy, JB Weld 24 hour epoxy, and Gorilla 24 hour epoxy. They eventually became loose and started to pull out. It's not my prep!! I've been doing this a long time!! The only thing I didn't try that was recommended was golf club epoxy. Might be worth a try if you're committed to using the HIT inserts. I am convinced that there is something in the chemistry with those shafts that inhibits the bond with HIT inserts. Or maybe the inside dimensions leave too much of a gap. I came up with a build using Iron Will components and Axis Match Grade shafts that will give me a very close final arrow weight as the TKOs, but not quite as high of a FOC. I'm really not concerned with FOC as long as it is >=10%. Good luck!
