Assemble F775 rear aft skin to the bulkheads. Prep and rivet the F656 gussets (4) to the bulkheads. Assemble the forward aft skin F7112, rib F787 and gusset F788. I spent a lot of time putting the skins on and off today. Initially put the skins on and realized I needed to do some more fluting to the flanges, so off came the skins.The I reassembled everything and fit the gussets into the correct positions. Once they were clamped down the skins came off again. I could then drill the holes and prep the gussets for assembly. Reassemble again. Install the forward aft skin and fit the upper rib and gusset together. Began to check out the F7112 canopy stiffiners. They need to be bent, fluted and cut to fit, not necessarly in that order. That will be a project best approached slowly and carefully.
