The J-Stringers for the Right Wing were cleaned, deburred and primed. These stiffen the Top Wing Skins and are the last to be riveted after the those Skins are riveted in place. I started prepping parts for the Left Flap. Ishan helped with the riveting today. The Top Skins on the Right Wing are now completely riveted except for the line of rivets attaching the large Outboard Wing Skin to the Rear Spar. Those rivets will be much easier to set when the Wing is in the Cradle. We removed the Right Wing from the Stand and placed it on the Wing Cradle. The Left Wing was positioned onto the Wing Stand.
