A trick with a rubber band saved a stuck film advance lever on a Canon AE-1
I had a customer bring in an AE-1 last week where the film advance lever was totally frozen, wouldn't budge at all. I was about to start a full teardown, but I remembered an old timer saying to check the bottom plate ratchet first. I put a thick rubber band around the lever for extra grip, gave it a firm but careful twist counter-clockwise, and it popped free. The ratchet spring was just gummed up with old grease. Has anyone else had luck with this before going deeper into the mechanism?
