Notched the aft end of HS-404 ribs to fit around HS-710 and HS-714. Fluted and straightened the ribs HS-404 HS-405 HS -706 HS-707 HS-708. Marked the ribs "right" and "left". Very carefully measured and marked, then drilled to size #40 the hole locations on the forward flange of HS-405. Clecoed together the left side spars HS-702 HS-603PP and the left ribs HS-706 HS-707 HS-708, then drilled all rib to spar attach holes with the exception of HS-708 to HS-603PP. Dissasembled and deburred the holes and re-clecoed then clecoed on the top half of HS-601PP to the rib-spar assembly.
