Brief Description: Dimple Aft Skin, Make Extra J-stringer
I set up the C-frame and dimpled the aft skin for the J-stringers. I'm planning to use the Super Tracks mod to extend my canopy travel, so based on Ken's experience in installing I made a third J-stringer to go down the center of the aft skin. I made two angle brackets to support the ends of the stringer. Drilled and cleco'd the brackets to the F-707 and F-708 bulkheads. Cut a section of J-channel to length and trimmed the ends similar to the other J-stringers. Finalized the fit and finished the ends. I used the rivet fan to layout rivet spacing down the centerline of the skin. Centerpunched and drilled the skin.
