Section 10 - Aft Fuselage (several more bulkheads; bellcrank rib assembly)

A decent amount of progress was made since the last post - deburred and riveted the 3rd, 4th and 5th bulkheads (front 3), primed several parts used for the bellcrank rib assembly (as well as future parts of the build), and attached the large (forward-most) bulkhead to the assembly. Having a large structure on the two sawhorses was very satisfying ... this puppy is starting to take the shape of the aft fuselage.

Riveted the 3rd bulkhead to the doublers and horizontal stabilizer attach bars:

Primed various parts, including the battery angles (in front) that form part of the bellcrank rib assembly:

Assembled bellcrank rib assembly:

Bellcrank rib assembly riveted to 5th bulkhead (largest) - note they are upside down on these rather large (40" tall) sawhorses bought specifically for this section of the project.
