Productive day working on the aircraft. Riveted the W-1203B-L Outbd Wing and W-1202B Mid Upper Wing Skins. Dimpled the 3 holes in the W-1201C-L Wing Walker Doubler, bent the forward edge and deburred the edges. Primed the Wing Walker Doubler and the part of the Inbd Wing Skin where it will sit. More riveting tomorrow.
