I disassembled the Aft Fuselage section I assembled yesterday. Like I previously posted, I wanted to get a visual of the pieces assembled together. Today, I started work on the F-01475 Top Skin. I started by completing the Alumiprep and Alodine work. After waiting for the Skin to dry, I applied the Akzo Epoxy Primer. Here is the Top Skin after the primer dried.
I mixed up enough Akzo to also prime the U-00018 Tail Spring Mount. Here is the Tail Spring after the primer dried.
As I have done with all of the other sections, I like to prime the rivet lines on the outsides of the Skin. Here is a shot of the F-01478 Bottom Skin after I primed the rivet lines.
There are four pieces that make up the Top Skin assembly.....The Top Skin, J-Stiffener, Upper Aft Fuse Rib, and the Skin Doubler. In the picture below, all four pieces are riveted together. I used the 3.5" Back Rivet Set for the rivets on the J-Stiffener, but due to clearance issues on the Fuse Rib, I had to use the 12" Set.
I did notice one "issue", if you want to call it that. The plans call for all 51 of the rivets to be AN426AD3-3.5 flush rivets. When I inserted the rivet into the one of the five holes circled below, it looked to short. I used a guage to confirm my belief, so I used 3-4 rivets for these five holes.
