No, it shouldn’t come to that.
I can’t remember what I did exactly when this happened to me – actually it seems I can, see below – but I have vague memories of tapping a thread into the inside of the tube at the opposite end to the lever then screwed in a suitable bolt and used that to start the Maxle moving.
Edit: yeah, I borrowed a suitable tap and bolt from a mate who works in a Uni CNC engineering lab. Just screwing in the tap was actually enough to move the jammed Maxle, but if it hadn’t I was going to thread in the bolt and use the head of that to move it. Once it’s over the initial force to move it, should come out easy. You need to measure the internal diameter of the Maxle then source a suitable tap – local engineering shop should do it if you can’t find what you need.
