Remember my buddy who bought that camera based on the shutter rating? It died at maybe 30,000 clicks. He was in Florida, so the heat and damp air just cooked it. The repair guy said the spec sheet means nothing once real weather gets involved. That's why I never quote those numbers to people asking for advice. It just gives a false sense of security.

My old boss had a hard rule about three passes max. If it doesn't budge after that, you're just causing trauma for no real result. Sometimes the skin needs to calm down before you can try again, or you just leave it be. It's a service, not a punishment.

Helicoils are great until you cross thread the install tool. Ask me how I know.
