Match drilled, dimpled and machine countersank both left and right static air ports which I ordered from Rivethead Aero. Deburred and riveted ports on both sides. Was able to press another helper from work into coming over and assisting me with riveting, Josh Jors and I got most of F-1075 the Aft Top Skin riveted in place. I started riveting on F-1014 Aft Deck to the tailcone structure.
