Well I riveted the R side of the HS skin. All went well until I noticed all rivets done on the main spar have distorted the skin. Ribs and squezzed rivets are fine. Is it possible I did not coutersink deep enough? I made a test piece of dimpled skin and checked to make sure it was sitting flat on the spar when countersinking. Or is it possible my gun operator is doing something wrong? I would think riveting on the thicker spar material should go easier.
