Fuselage Center Section #5 - aft center channel bulkhead.

 Priming session!

After what seems like hours and hours of deburring and etching/scrubbing, I got to prime some parts!


It is getting hot and humid in East Tn so the fan came out!

Parts on the rack for priming.

All done!

These parts are for bracing the side skin to the main center section channel.

Other side.


All done.

These parts add a flange to the otherwise flat center section assembly that is pre-riveted together by the factory.


Done!

Next the vertical uprights get riveted to the aft center section bulkhead.

Solid rivets get squeezed here.  Leave the top holes open.

Tails...

The other side gets the same.

Then the aft bulkhead gets riveted to the center section channel.

Solid 470 rivets on the top row.

Solid 470's on these center 3.

Solid 426's on the dimpled holes.


All done!
