Back riveted trailing edge, halfway, starting with the middle rivet, then the ones on each end, then in between each of those until all rivets were half riveted. Turned the rudder over and finished smashing them with a mushroom set into my 4' long "rivet plate". A 4' piece of steel angle that I smoothed up a bit with my mini die grinder and a scotchbrite wheel. Put in the two pop rivets at the top rib that I received quickly from Vans. Used my new pneumatic pop riveter... that is fun. I just have a few of the tougher rivets to get to near the end of the ribs. Might have to use the pop rivets on the last hole on each side of the top of the rudder.
