Have used super glue jell for many years.
-BH fully tightened on unglued insert.
-Set nock end on flat surface.
-BH shaft end set just beyond a raised block.
-Slightly begin Insert/BH installation until Insert/BH just stays in the shaft
-Apply super glue jell
-Rotate nock until flush on flat surface
-Install Insert/BH rotating during full insertion stopping when BH is in virtually immediate alignment.
Note: May appear on the surface as complicated, however quite simple, easy, quick, consistent and effective
Same process I utilize when installing 2 or 3 blade heads
No issues...
