Empennage



I spent the afternoon riveting the right elevator. There were ten steps in the plans to accomplish the task. E-703 to E-704; E-610PP, E-611PP,and the platenuts to E-702. E-709 to E-702; E-703/E-704 to E-702. WD-605-1-R to E-702 and E-709; E-713 to E-701. This step was a little confusing at first until I realized that by riveting this first you can reach inside to squeeze the rivets. Any other way and you'd have to use blind rivets to attach these four rivets. Then I put the E-714 in place loosely and then inserted the elevator skeleton into the E-701/E-713. With all that done I finally was able to cleco and rivet the skin to the understructure and finish attaching the E-714 counterweight. I was somewhat concerned when I finished up that the elevator seemed to be overbalanced and the counterweight was way too heavy. I read through the plans and was relieved to find that this is intentional. They want it overbalanced to account for completing the elevator and painting.
