I spent most of the today’s session Akzo Priming all the parts that were treated with Alumiprep and Alodine yesterday. Pictured below are the Inboard and Outboard Hinge Bracket to Nose Rib assemblies after being Akzo Primed and riveted together. The two assemblies on the top are the Outboard Hinge Brackets and the two assemblies on the bottom are the Inboard Hinge Brackets. All four of the assemblies are held together with AN426AD4-4 rivets, except for the four AN426AD3-4 that attach the two MS21055-L3 nutplates on the Inboard Hinge Brackets.
While the second batch of parts were drying, I continued work on the A-710 Stiffeners. I removed the blue protective coating and began preparing the Stiffeners as described in the excerpt below.
In the group of Stiffeners below, you can see the two on the bottom left have been trimmed and prepared. I used the one named “The Man” as a template for the remaining Stiffeners. If you look closely, you can see the blue sharpie marker outlining where the remaining Stiffeners will be trimmed. It’s going to take awhile to complete all of these Stiffeners.
After the second batch of parts dried, I clecoed the Main Ribs to the Inboard Hinge Brackets.....
.....and the Main Ribs to the Outboard Hinge Brackets.
During the next session, I will rivet these two assemblies together and continuing preparing the Stiffeners.
