Front drum self-adjuster

This happened to me on one of the drums of my 72 a couple years ago. I was able to use a RBFH to tap the drum off. Think a motion like you're playing tug-of-war, hitting the back edge of the drum with the "bottom" of the RBFH's head. (What I was actually using specifically was a small sledgehammer). If yours is on tighter than mine was, you may not have as good of luck as I had, but it sure beat messing with that star tool.
