Dan, the best glue I've tried to date is the black HIT adhesive from Easton. I take a bore brush and deglaze the inside surface of the shaft, use a 3M pad (red) on the insert and then clean both the inside of the shaft and outside of the insert with 98% alcohol. When its all dry I put the HIT adhesive on the insert and a drop at the edge of the open end of the shaft. The insert gets quickly put in with a twist. The insert is held in tight for 30 seconds against the table. Wipe off the excess adhesive and you can shoot it in 15 minutes. I've done this tons of times with internal inserts of the Axis shaft.
