Similar to JB Weld that Ted recommends is marine grade epoxy, which I think is actually better, but either is excellent. I had trouble with other epoxies and various types of glue breaking down before the AD shafts broke down; however, once I started using marine grade epoxy, I have had no more of those problems, and that is with using heavy arrows (up to 1000 grains) and 70 pound bows and shooting into very unforgiving substances, like rock and hard woods. Ted's advice on cleaning is also imperative to follow.
