21 APR 15: Priming: 2.5 hours

Got the whole batch primed this evening:

22 APR 15: Page 26-5 step 7, pg 26-2 step 5: 1 hour

Riveted the left and right rear seat rib assemblies:

24 APR 15: Page 26-2 steps 6-7: 2 hours

Riveted the nutplates, reinforcing angles, guide brackets, seat belt anchors, and scat tube flanges to the F-1016F-L/R inboard seat ribs:

25 APR 15: Page 26-3 steps 7-10, pg 26-4 steps 5-6, pg 26-5 steps 6-7: 7.5 hours

Dimpled the outboard seat ribs and intercostals.  Riveted nutplates to the intercostals.  Riveted the F-1016D trimmed seat belt attach bars and F-814PP forward seatbelt anchors to the F-1016-L/R outboard seat ribs.  Riveting the seat rib intercostals and spacers to the ribs:

Seems like yesterday that riveting was some sort of mystery.  Now it is second nature.  Forming the shop-head is almost intuitive.  Quick work, but with nice results.  I guess after thousands of rivets, I should be proficient… There is a spacer under the flange – makes it look like a gap:

Inserted the VA-175 heat duct tee into the tube flanges on the inboard seat rib subassemblies.  Clecoed the seat rib subassemblies to the aft center section bulkhead assembly.  Mmmmm….one of these things doesn’t look like the other…

The good part about all the riveting experience is that you get good at drilling them out!

This looks a bit better:

Riveted the F-1066A flap actuator bracket – was able to get all the rivets with the squeezer:

Tight quarters, but they all turned out nicely:

Riveted the seat rib subassemblies to the aft center section bulkhead assembly:

Finished the session by riveting the outboard seat rib subassemblies and the bulkhead side channels to the rear spar bulkhead assembly:
