Beginning to assemble the left leading edge assembly. Begin with drilling 2 #10 holes for the stall warning vane and file the area between the holes into a slot. Came out nice but will probably need to be adjusted once the stall vane gets installed. There is one section of J Channel on the top skin that needs to be cut to size and deburred. Then it gets clecoed into place on the ends and match drilled to the skin. I put in the ribs as a check to make sure the J channel was aligned properly with the slots in the ribs befor ematch drilling to be sure the J channel did not rub on the ribs.
