That's a fair point. From what Ed did (and did not) say, I was assuming
his pole had a simplest kind of tapered friction lock... which turns out
to be so. These often can be freed by end-on impact when twisting
doesn't work and squeezing might crush the thin walls.



I guess if I use a somewhat soft wood as a backstop, I may resort to
that. I'm going to give the tubes another week to dry out before resorting
to further violence! :^)
