I have a few bad rivets in my rudder stiffeners. I'm wondering whether it would be better to leave them, than risk irreversibly damaging those thin rudder skins trying to drill them out. I don't have more than 2 questionable rivets on any single stiffener. My fear is that those rudder skins are so thin and flimsy that I would destroy them trying to drill out those rivets.
Suggestions?
