| Top skin 100% + 9 rivets |
The nose and end cap ribs are placed in between the skins and forward spar. Since they were previously dimpled, they just snap right into position and after a few clecos to make sure they don't move, they are attached using the squeezer. In this photo one of my mistakes can be seen. Wait for it... See the rivets next to the little arrows. Yes? Well you shouldn't. I was having so much fun with the squeezer, I accidentally put rivets in those holes that were supposed to be left open. By a merciful act of divine providence, I caught the error before I had filled each of the ten open locations. It was my good fortune that I only had to drill out nine.
After the ribs are in place the rear spar assembly is set in place. Since all of this was previously match drilled, the fit is very near perfect.

The last step is to use pull-rivets to fix the ends of the two middle ribs to the rear spar. Shown below is the Harbor-Freight pneumatic/hydraulic rivet puller. This is an awesome tool and inexpensive too!

And now, on to the vertical stabilizer...
