Fuselage, MID Lower Structure (Part 17)

In the previous session, I started dimpling the Center Bottom Skin.  I used my pneumatic squeezer with a 3” yoke to dimple as many of the holes near the edges as possible.  To start today’s session, I used the pneumatic squeezer to finish the holes around the edges and then the DRDT-2 to finish the remaining holes in the Bottom Skin.  Here is the dimpled Center Bottom Skin.

Pictured below is the F-01448C Gear Brace Brackets, F-01415A Seat Rib Angles, F-01416B Seat Rib Angles, and the F-01448B Gear Brace Bars.  The first three parts were connected together in the center and had to be separated into -L & -R parts.  Here’s the three parts after they are separated.....

.....and after the edges are cleaned, all the holes deburred, and the appropriate holes dimpled.  These parts are now ready for Alumiprep, Alodine, and Akzo primer.

Kinda hard to see, but this is the F-01448A Aft Gear Brace.  This part has had the edges cleaned, holes deburred, and the appropriate holes dimpled.  This part is also ready for Alumiprep, Alodine, and Akzo primer.
