It feels great to rivet again. This evening I clecoed the forward skin on the canopy frame. (I also clecoed the support sections on also. Thank goodness, I noticed my mistake before I started riveting. If you fivet the supports on first, you can't get to the forward rivets on the skin.)
After I was sure everything looked and fit correctly, I started riveting. (I only goofed up 4:-) I was able to squeeze the rivets along the sides, but needed to use the rivet gun on the rest.
I still have a few rivets that I'm not happy with. There are two rivets along the front row where it is almost impossible to get a bucking bar in place. I'm thinking of using pull rivets if I can't come up with a better solution.
