This session started by repeating the work that I did yesterday on the other side of the Horizontal Stabilizer, by riveting the two nose ribs onto the other half of the skin section. This work seemed to go a little more quickly than it did yesterday, probably because I had fresh riveting practice. Once those two final nose ribs were riveted, I positioned both skins on the cradles and then positioned the forward spar assembly into place. This was then followed by loading up several dozen clecos to hold everything in alignment and it was very satisfying to see such a huge assembly coming together. Finally, I installed the dozen blind rivets that hold the spar assembly to the nose ribs in the skin with my hand riveter tool. This was challenging due to the limited space within the skin and the placement of the ribs, but I managed to get it done. What's next? Some double-offset riveting near the center of the spar.
