RE: Recommended adhesive
The stuff in the link is supposed to be better than Ferr-L-Tite. Even the brown glue sticks you get at the hardware store is supposed to be better.
It makes sense they've come up with better formulations than Ferr-L-Tite over the past 40+ years (that's how long I've been using it.)[&:]
Lots of people use epoxy to glue their adaptors in, but I like using hotmelt. I can reposistion the broadhead a lot easier if it doesn't spin true after I've glued it up.
