Fuselage, MID Lower Structure (Part 10)

Today’s session was spent preparing Baggage Ribs for Alumiprep, Alodine, and Akzo Primer.

These are the F-01480 Seat Belt Attach Lugs.  They came attached to each other and had to be separated....kinda looked like a rivet fan!  Anyway, I separated them using my bandsaw, cleaned the edges, and deburred the holes.  

The four triangles (kinda looks like two sandwiches cut diagonally) are the F-14128 Seat Belt Lug Brackets.  The two Ribs are the F-01424-L & -R Baggage Ribs. All the edges were cleaned and the holes were deburred and dimpled.

The Ribs on top are the F-01427-L & -R Baggage Ribs and the Ribs on the bottom are the F-01426-L & -R Baggage Ribs.  All the edges were cleaned and the holes were deburred and dimpled.

The two Ribs on the top are the F-01415-L & -R Outboard Seat Ribs and the two Ribs on the bottom are the F-01423A-L & -R Outboard Baggage Ribs.  All the edges were cleaned and the holes were deburred and dimpled.

I don’t like to dimple holes AFTER I have primed them.  Doing so, usually cracks the primer and it flakes off requiring touch up.  So, I looked several pages ahead to determine which holes get dimpled on these parts.  Now, all the parts above are ready to be treated with Alumiprep, Alodine, and Akzo Primer.
