I have a pair of quite old Black Diamond Alpine Carbon Cork Flicklock trekking poles. After much use and abuse the tip on one of them has finally gotten bashed in (the carbide tip has either broken or been pushed back completely inside the plastic mount and although still usable the pole is now nowhere near as secure when in contact with rock).
I managed to remove the busted tip by following the instructions here which suggest dipping it in boiling water then wrenching it off with pliers. It did actually come off surprisingly easily once heated (but before that I couldn't budge it at all).
I have also secured a Black Diamond "Flextip Replacement - Long" (well actually a pair, and small "trekking" baskets). Black Diamond don't provide any useful instructions, and the site linked above just says:
To secure the new tips, tap them on a hard surface like concrete a half-dozen times. Do not use glue.
but I'm dubious about this: I can easily imagine the new tip disappearing into the next sucking Scottish quagmire it encounters if not firmly fixed to the pole. I'm guessing the original tip was glued on by some sort of thermal-sensitive glue; hence the boiling to release it. The site linked above also mentions "old glue residue".
What sort of glue should I use to fix these? Obviously something which will let me repeat the boiling trick if/when the next time the tip wears out would be ideal, but my Google-fu isn't having much luck identifying such a thing. Or does the just "tap them on" approach actually work in practice?
