Don't cut the damn thing off!
I got the clamp upgrade kits for two of my poles and, rubbing my hands in anticipation, got to work. Cut cut cut, oh! I totally forgot about not whizzing the top Clamp off. Had to go to the dustbin, retrieve said clamp. Fortunately, I had cut it straight off the pole as the pole was quite worn at that p ; ;DDoint, so I just squeezed the pole remains in a vice and the clamp came away with no damage, lucky for me. Glued it back on .
