I had Amber’s help this evening and we completed the riveting of the side skins to the bottom of the fuselage (the seams between the side skins and the bottom skins).
I put a thin layer of 3M Firebarrier between the forward side skins and the firewall flange before we riveted.
Everything came out great. The rear seams are tight where they overlap and the forward skins butt tightly together.
We now need to rivet upwards on forward skins.. almost there!
