Fuselage center section #26 - Seat rib area assembly

 Finished the seat pan area by riveting the two subassemblies to the main center section.

After spending most of the day reorganizing and clearing clutter from the garage, I was able to cleco the two seat pan sub assemblies to the main center section.

Installed the rivets on the top side, the outboard ones are flush rivets.

Other side....

Tipped the whole thing on its side to rivet the ribs to the center channel.

Had to get these with the hand puller.  My arthritis does not like this!

 

All done!

Fuselage center section #25 - Seat rib area assembly/priming

 I primed the missed seat pan parts in the morning and did some assembly in the afternoon.

I found the upper humidity limit of the waterborne primer I am using.  Got a few flaws in the finish from some almost runs because I was priming early with too much moisture in the air.  Once it dried it was acceptable so I did not bother with sanding it off and priming again.  It will all get sanded prior to paint anyway so it is what it is for now.

Riveted the nutpates on the front edge of the seat pans.

Riveted the nutplates around the access hole of the seat pans.

Riveted the seat pans to the rib subassemblies.  A few holes get left for later.

Riveted the nutplates to the inboard edges of the seat pans and ribs.

Other side.....

And riveted this brace that will eventually rivet to the side skins.

Other side....

 More seat rib area assembly!

Got to the point of riveting and bolting this attach bracket to the rib and found out that I got out over my ski's a bit by installing this nutplate before I was told to.  No way to get this screw in with the nutplate installed so I had to drill it out.

Nutplate removed.

Screw installed.

Nutplate replaced.

Flap motor bracket installed.

Reinforcement brace installed.

Mixer assembly going in.

Crotch strap anchor points going in.

Both subassemblies done.

Missed prepping a few parts so I went ahead and got them ready to prime.  Had to cut two parts out of this thing.

Removing all the excess flashing.

Deburred the seat pans.

Dimpled as required the seat pans.

Fuselage center section #23 - Seat rib area assembly

 Started assembling all the parts that were prepped and primed for the seat rib area:

Seat back angle adjust brackets get assembled.

And then riveted to the proper ribs.  Make sure you have the correct orientation and the correct rib!

Then the seat belt attach points get riveted to the same ribs.

And finally a couple attach brackets.

Fuselage center section #22 - Seat rib area priming

 Got started by priming all the parts that I had prepped.

Fuselage center section #21 - Seat rib area prep

 And even more edge cleanup and deburring of the parts.  Mostly the ribs tonight.  Got them all done and now will try to get them primed tomorrow after work.  There are a ton of parts in this batch....most are small and then the 8 ribs will take some time to etch, scrub, dry and prime.

 No pictures just tons and tons of cleaning up part edges and deburring holes.
