This evening I started by hanging plumb bobs from the spar and checked the twist in the right wing since I had put the tank on. It is within 1/32 so I know it's okay. I then clecoed the top skins on. When Reva got home she came out and we riveted about 4 of the ribs on the inboard skin and called it good for tonite. The plan is to get it done by Thursday. Then I will start on the flaps.
