Pop lugs, not drugs
I've been thinking about cutting the base off and putting in a bulkhead with an I bolt, but am concerned about epoxy not sticking to the plastic nose cone. I'd like to use the cone for a tracker av bay at some point also.
You can help yourself out by really scuffing the interior surface, cutting ex marks with an xacto or little dips with a dremel, and using a thick epoxy like rocketpoxy. That was Eric's advice to me when I had to bond stuff to that slippery polyprop cone material. You can also place the bulkhead beyond the shoulder and use that internal lip to your advantage (just need to squeeze the shoulder a bit to get it in there)
