Tough to call the time because Dave and Mark stopped by. I clecoed the rib structure together. Drilled it. Took it apart. Deburred it. Put it back together. We then clecoed the skins on. That was cool to see it take shape. I then located the 404 and 405 middle and nose ribs. Removed and fluted. Squared flanges. Reinstalled and they are now ready to drill.
