In section 29 working on vent doors. I'm on step for final drill and counter sinking for rivets. Instructions say to counter sink outer skin. The rest of the skin is dimpled. And the vent parts are all under .040, so are thin enough to be dimpled too. Anytime I counter-sink in metal this thin deep enough to flush rivet head, I tend to get oversized holes.
Question, can I dimple these parts instead of using machine counter sink? If not, since parts are layered, will it prevent getting oversized hole if I do machine counter sink?
