Arg! Following the plans to my best interpretation, I started drilling holes into those side braces. After drilling 3 of them, it felt wrong….again. I stopped, and re-examined the assembly, and concluded that they should be inline with the longerons. That make more sense. If only the plans had a blow-up of this portion. I repositioned the braces and drilled all the holes. The question is, does the brace with extra holes need to be remade? I decided no. The holes are small and shouldn’t created a significant structural weakness. I just hope this is the correct position.

When on to tail cover with the lightening hole, drilling holes.
