Matchdrilling center fuselage

Category: Center fuselage — Steffen @ 16:49 — Hours: 6.5

I had a very productive day today, made very good progress on the center fuselage.
First I marked and cut the two center seat ribs. They need to have this opening, to allow the flight control assy to be installed.

With those done, I could start clecoing the center fuselage together.

After matchdrilling the bottom skin to the ribs, I lifted the assembly to the table.

The outboard ribs needs to curve to form the fuselage shape. I marked the fluting positions between the rivet holes.

I also had to cut about 1/5″ away from the forward edge, to make it fit into the F-704 bulkhead.

With the bottom flanges fluted and drilled to the bottom skin I marked the holes for the seat pans, so I could flute the upper flanges.

Last thing I did today, was to deburr and matchdrill the baggage area corner ribs to the bottom skin.
