I started my riveting session tonight by letting my bucking bar go off kilter on a J-stringer/side skin rivet and leave a lovely 3/8" ding in the skin just below the stringer. Ding may be the wrong description. It's a nice, sharp imprint from the square edge of the tungsten bucking bar. I can massage it from an outie to an innie so that prior to paint I can make it disappear with a little filler, but I'm not sure if such a sharp indention needs more than that, like stop drilling the ends and either dropping rivets in or just filling the holes prior to paint. Will sharp dings like this in a side skin (not a control surface scenario) eventually crack, or do I just fill it later and call it a day?
I immediately moved to back riveting the stringers using the big Cleaveland back rivet bar. Much better.
