Took most of the week to install the tank ribs. I only had a 2 hour window to install 3 ribs starting from when I mix the proseal. In a 2 hour window, i was able to install 3 tank ribs. This includes putting the proseal on the rib flanges, place the ribs into the skin, cleco 3 on each side, rivet them in place, and finally putting proseal on the rivets inside. I also completed installing the J Stiffeners using the same method. Lastly, I also installed the T-1005 tank attachech bracket subassembly onto the tank, also using the same method of proseal, riveting, and presealing the rivets on the inside.
