[quote=Dogboy]Are you talking about a Hotstick?
If so, they can sometimes be salvaged. If you look at the inside tube, you will see that it is not circular, one side is fatter than the other. This is how the end of the larger tube engages when you twist. The edge of the inner tube can wear down allowing the outer tube to slip past when rotating. When this happens, the stick won’t lock. You can build up the edge with resin to get the stick to lock again but it is a bit of a PITA because if you go too thick, the outer tube will bind and you’ll have to do some sanding. It is a bit of a trial and error process.
The other thing that can happen is the inner tube can split length-wise. This allows it to flex when twisting and the outer tube will slip past. This is also repairable with some work. When my hotstick did this, I removed the end fitting and epoxied in an aluminum tube to reinforce the cracked tube and also epoxied it along the split line. That hotstick has held up fine for many years since repairing.
