Finished up the aft tunnel zee sub assembly. Pilot drilled the aft support to the zee skin, then added the F16-07 gussets on each end.
Fabricated SNX-F16-08 clip.
Cut fwd tunnel zee skin to length. Angled the top piece to match the angle of the fuselage sides. Drilled pilot holes in the top edge to allow mating with the aft zee. Notched the lower corners to accomodate the lower longerons. Marked and center-punched rivet hole locations on the left and right ends.
