Once again I got stuck late at work so I didn't get as much done as I would have liked. I fabbed up the F-629 channel which provides support for the F-606 bulkhead and is also 1/2 of the elevator bellcrank support.
I also installed one of the gussets that stiffens the sides of F-606 to keep the bulkhead from twisting. I used a blind rivet (CS-4-4) for the outside position since there was no way for me to get a flush set in there.
