Made the aft shear web by attaching angles. At first I riveted upside down, so I had to drill out all the rivets, flip it, and re-do it. No biggie, none of the rivet holes got enlarged.
I then started tackling the aft fuselage tailcone. The first step is to set distances and angles by attaching the bottom skin to the lower longerons. I was afraid that the offset I made for the skin to fit inside might be a little shallow, but the 0.025 skin nestled in very nicely, perfectly flush.
