Riveted the left hand rudder skin to spar, except for last three holes as for RH side. Match drilled the Al angle I bought at OSH to the trailed edge holes. Clecoed the trailing edge w/AEX wedge to the angle. Probably should have roughed up the trailing edge skins for the tank seal before riveting the skins to the spar, but as long as I set no rivets on the top and bottom ribs I can still do that.
