I used my Avery pins to temporarily attach the elevators to the horizontal stab. I marked the fiberglass tips with a Sharpie and made the intitial cuts on the bandsaw. I think I will sand them down just a smidge more to gain addtional clearance between the tips and elevators. I have been debating whether to glass over balsa wood or foam for the tip inserts. I decided to try balsa wood. I may try to make the second from foam and see which I like best.
