Tonight I started riveting the side skins onto the aft fuse. I started with the longerons, where I could use my squeezer to set all the rivets. To assist with alignment, I packed up the front edge of the yoke, one for the bottom row of rivets, and a larger pack for the top row. This worked out nicely and everything set well. I did both sides, except for a few rivets down aft where I plan to leave things open until I have the aft bottom skin riveted on.
