Deburred, fluted and straightened the VS parts. Assembled and match-drilled the rear spar assembly for the VS. Clecoed the front spar and ribs to the rear spar assembly and match-drilled the #30 holes. Clecoed the VS-901 skin to the spar and rib assembly. I am now ready to match-drill the #40 holes that attach the sub-assembly to the skin.
