Hey clever people, hoping someone had an idea on how to undo the collar.
Thought I’d give it a quick clean and adjust the collar after but must have been cross threaded as it’s not budging!!
They only way I thought to do it find a fitting screw in the retaining hole and then give it a good knock but will likely mash the thread, so before I go last resort was hoping people had some good ideas to try first!! 🤞
