Started by deburring the HS-1001 skins using the vixen file to knock off the nubs from the manufacture process followed by a few passes with the die grinder and 3m wheel.  Next installed the HS cradles, skins, HS-905 nose ribs, then spar/inspar assembly, followed by the stringer assemblies and lastly the rear spar.  Match drilled the rear spar to the ribs to end the session.
