Installed the rear spar into the assembly and riveted it to the spars and skin. NO issues and was happy with how it turned out.
Using my new riveting technique I drove the 4-7 and 4-8 rivets into the front spar and interspar ribs. This was something I feared before I figured it out. Previous I had to drill out one of 2, this time I drilled out one of ten.
HS is completed up to fairings. I like what I see and think I see progress on my quality.
