So now it is time to start riveting the ribs to the main spar. This is a nerve-racking time. The spars are very expensive, and something that you do not want to mess up. So I took my time, and made sure that I was ready for every rivet. There are a total of 14 ribs to be riveted, so it takes a little while. Each rib had 5-6 rivets. Once I started to get into a rhythm, it went very well. Overall, I only had to replace two rivets.
After the ribs are riveted to the main spar, they are then riveted to the rear spar. This is much easier, as a different tool can be used. The entire process is then repeated on the right side.
