continued working on center section. finished rivetting and screwing seat pan and controls access plate. Removed wings. <<(* Note added much later. it was a mistake to remove the wings at this time. Should have had all eight center section ribs instaled before removing wings. *)>> Turned center section over and began work on bottom skin. copper clecoes installed along main spar and bottoms of seat ribs. Next task coming up is bending the bottom skin vertical for attachment to aft spar. Need to verify clearance from top corners of seat ribs, and proper attachment of aft tab of seat ribs to aft spar. followed by drilling, deburring and rivetting.
