Cut to length the J stiffeners, trimmed the ends to fit the bulkheads, and marked the line on the skin side. Put together the aft tail section, but I'm still working on the aft most section to line up. Also, still have some fluting to do on the bulkheads, so I'll be taking it apart, and putting it back together. Hopefully, I can take one bulkhead out at a time, flute and reassemble. We'll see tomorrow.
