Washed and dried the various brackets I have made for tubing and wiring. Primed with NAPA 7220 self etching primer. While parts were drying I cleco'd top forward skin on to locate the center rib. Looked at plans and parts to decide on a way to drill the center rib to the firewall since there are no holes pre-punched in the rib or firewall.
Used the squeezer to rivet on nutplates to the brackets and rivet brackets to ribs and J-channels.
