I use an epoxy that I get from a golf company called Leaderboard Golf that is
made for glueing the shafts in golf clubs. It is super strong, fast curing, doesn't
get brittle with age, and is available in bulk sizes at a cost savings. If you buy
large sizes of any epoxy it will last longer if you keep it in the refrigerator.
(Don't let the kids drink it !!! )
