Brief Description: Completed F-704 Center Section Bulkhead
I finished the F-704 bulkhead by riveting the vertical spacer bars and vertical side members to the aft bulkhead, and the vertical side members to the forward bulkhead. I aligned the parts using some of the hardware that will eventually be used to attach the wings to the airplane. This should ensure that everything is lined up. Many thanks to local RV-7 builder/flyer Hal Lyons for loaning his very well made laminated wood bulkhead spacer blocks to me.
I also enlarged the F-704J spacer holes in the aft bulkhead to 15/64 then reamed them to 0.249. I performed this step while the two bulkhead halves were aligned with two 7/16 bolts though both the forward and aft bulkheads on each side so I could use the final size spacer bolt holes already in the forward bulkhead as alignment holes.
Thinking I was done, I took photo 3 then noticed I hadn't installed the three rivets outboard of the vertical spacer bars on each end of the aft bulkhead. This was easy to take care of this after I separated the forward and aft bulkheads for storage.
