I got started on riveting the leading edge. The plans call for starting at the most aft end of each rib and moving forward evenly on both sides. I started with the rivet gun even though the plans mention setting the first row with the squeezer. I was pretty rusty with the rivet gun and had to drill out several. I also made a bone head move and dropped the bucking bar inside the leading edge creating a couple nice dents. After that I placed an old towel inside each cavity and I worked them. I got the squeezer out and completed setting the first row and the second (with the long yoke). Fustrating night.
