While expecting Fred to come back help me any day, I felt that we would be more comfortable riveting the F826 and F827 skin panel to the seat rib structure sub-assemblies if we place the assembly vertical in a jig. Original plan was to do that with the sub-assy laying on saw horse, with the bucker sitting on the ground underneath, and the "gunner" on top. Since I was having back pain at the time, I didn't want to do it this way. I decided to take the time to design a pick-up jig made of wood. I went to Rona first to purchase some wood and hardware.
