comb92, if that is a grease point on that white gizmo....that would mean there's a hole though the outer tube below that point somewhere. Maybe that grease point can be pushed outward from within the steel tube to allow it to slide backwards or even forwards to remove it for resizing? Just a thought. (But then why the adhesive goop?) If so, you could mimic its features and drill another hole after cutting the shaft to length. Same for the round steel collar. Still seems like a lot of work for something not necessary in this application.
