Looking to stick our 7.5" V-2 fin can to a Fiberglass tube during a rebuild, what's the best method?
Well, I surely have less applicable experience than Top does, but I'll keep the ball rolling with questions.
What kind of plastic? One's glue options are very different with, just for example, PVC, polystyrene, and polypropylene.
Would you consider mechanical fasteners like rivets? Or threaded rods that are anchored in a bulkhead inside the fiberglass airframe and extend through the centering rings in the fin can, with the fin can held in place by nuts on the rocket's bottom? In the latter scenario the same rods and nuts can hold a thrust plate.
How long is the shoulder? If there is not a lot of contact area then a glue that is pretty good (for the materials) may not be good enough.
Which piece has the shoulder? The fin can, I would suppose. I don't think this makes much if any difference, but when someone who has more experience with this responds to tell me that I don't know what I'm talking about maybe he or she will include useful information too.:wink:
