Tried to do a marathon day and get the whole left wing done. No way possible. Got the front leading edge fully fitted & drilled. Cut out and mounted the landing light for left wing (both wings will have one). Fitted root doubler, wing walk, wing tip & flap/aileron hinges. Fully dissassembled wing, and deburred all ribs/misc parts other than skins. Dimpled leading edge ribs. Alumipreped & zinc oxided all ribs/misc small parts. Fully assembled and riveted wing frame/ribs & spars. Ready for final skin riveting!
