RE: Sig 1/4 J3 Kit converted to PA-18 Super Cub (Build)
Update:
I redesigned the way I was going to connect the "A" Pillar to the upper root rib. Initially i was going to have the metal rod bend at the top of the A Pillar and head down the root rib to towards the aft. After looking at the part I decided a bend was not the best thing to do. I felt as though the bend could just pull apart. So.... I drilled a hole parallel to the A Pillar into the root rib to allow the rod to stay straight. Now the force of flight will pull straight on the rod. This rod is already roughed up to allow the glue to bond but just for safety I am going to cut a barb into the end to really lock it in. The bottom will be glued along the fuselage side, which will have a doubler added to the area of the rod so it sits flush with the side.
Visible in the first photo is a hole in the first cabin former at the top. This hole will be for the reinforcement rods which will go from the former to the area forwards of the dash. These are a feature of a Super Cub and will be made from metal and functional. This is similar to the design of the Balsa USA Super Cub. Photos of the Balsa USA Super Cub are attached for reference.
Going to start and glue the fuselage together today.
