Today I continued to work on the support longerons running from the center section to the firewall. It took a little head scratching because two of the three longerons but upto the F-704 center section and one overlaps. I could not figure out how that was going to provide any structural support. Reading and research I finally found where the gusset is created that provides the structual support. So I worked on the left side first and to two of the three installed, then moved to the right side and finished the other two. I had to fabricate two small brackets to support the F-719 longeron. I got those built and in position. I still need to drill them to the firewall angle and the longeron.
