Brief Description: Began riveting longerons to top skin
While the top skin was on the fuselage transferred thetop longerons to the top skin. Removed the top skin and longerons from the fusaelage. I began riveting the longerons to the top skin. Discovered that a couple of the diagonal L brackets on the top skin were too long and stuck between the longeron and top skin. I had to remove some of the rivets in one longeron and remove the L brackets from the top skin. Was frustrated that I did not catch that before I began riveting. Will correct on another day.
