Riveted F-702A&B. Clecoed and match drilled all components of the F-705. Riveted the bottom corners of the 3 sections that make up the F-706. You really have to take your time here and make sure you know exactly what you're doing. Lot's of rivets don't get shot until later because other stuff gets attached to to this bulkhead later. Plus there is a mix of -3 & -4 rivets, with some dimpled for flush head & some not.

Seems like there's a problem with there the flange on the F-729A will eventually be in conflict with rivets that are going to be installed in a later step. I looked on VAF and tons of people have had this problem. The standard fix is to relieve the flange to make room for the rivet heads that will eventually be set in those holes.

There is also a singe lug nutplate that will eventually go across the top of the assy. If I notch out enough for that nutplate to lay flat it won't leave much ED for one of the rivet holes in the F-705A. I think a solution might be to make a shim/spacer to go under the nutplate leg and elevate it so that it's flush with the flange, rather than notch the flange at that location.

During the trial fit, I realized that I had missed the note on the print where the F-729C angle is bent to 88.5 degrees. I just put it in my bench vise and crept up on it. Didn't take much.
