Cleaned the outside surfaces of the HS skins and primered over the rivet holes prior to riveting. Riveted the HS-404 and HS-405 center ribs to the front spar assembly, and then placed the skeleton back on the jig to keep it out of the way. I'll continue the rivetting of the skins when Jackie returns from England in a couple of weeks. Meanwhile I'll continue on with the vertical stabilizer.
