I flipped the center fuse assembly back over and squeezed the rivets in the top of the ribs that I forgot yesterday. I then started in on the seat backs again. I marked one seatback for all of the holes and then clamped the two backs together and drilled them to #40 and then #30. I cut the hinges and drilled them per the plans, removing the eyelets as needed. If I hadn't screwed up the F-638 seat brace, I would be ready to debur and prime the seat backs. I ended the day by cutting the F-904L attach straps.
