Fuselage center section #30 - Seat rib area assembly

 Primed all the parts I had prepped and then started the fun part of riveting it all together:

Not shown is part prep for priming and priming.  Same old same old.  Deburr, round edges, slightly chamfer holes, acid etch and scrub, dry and then prime!


Riveting these corner pieces that end up securing the corner skins later.


Riveting the forward stub spar socket using a couple solid rivets.

Next is adding these doubler braces.


Some of these are solid and others are pulled.

Other end...

These doublers get riveted together with 3/32 universal head rivets which are smaller than the normal 1/8" ones.

All done!

Installed the center nutpates.  Top ones get squeezed and the bottom ones get the special SS nutpate rivets that are pulled.

Then these doublers are riveted in.  The top gets squeezed and the sides get pulled.  The bottom gets left open.

Back side.

Then this gets riveted to the rest of the center section.

These permanent seat pans for the outboard get riveted in.

And some nutplates riveted in.

Other side...

Started to cut these heavy angle parts and realized I need a new band saw blade.  This will have to wait!
