If you' re using a solvent to clean out the shaft, like denatured alcohol, be sure and let the shafts set overnight to let the stuff dry out before gluing the inserts. I was having a heckuva time with inserts pulling out before the dealer at the shop showed me an Easton (or was it Beman??) tech sheet on gluing inserts. I still lose a few with the superglue stuff, but not a single one with 24-hour epoxy. The quick set epoxies aren' t nearly as good.
