After priming the skeleton, I was able to set my first rivets. It is a little nerve racking doing your first. You are trying to be perfect. In the end it is no big deal. Even if you mess up a few, it is easy to drill them out and set a new one. Got the skeleton all riveted together (except for the portions called out for access to the skin rivets) and put the skin back on for final assembly.
It was a ton of fun riveting the skin on. I enjoyed this process the most so far. It starts to give you a sense of completion. It took a little longer than I expected, but everything went as planned. I think I only had to drill out one bad rivet (at least that I know of!).
The Vertical Stabilizer is now complete except for fairings which will come later in the process. One down, ??? to go. And yes, I was in my socks while finishing up the skin.
