Final assembly of the FAB. Used proseal between the lid and box, and the airseal fabric. This of course added a degree of difficulty to an otherwise easy task. Started by riveting the heat flange to the lid, with the door hinge and a piece of airseal fabric in the mix. After that was in place, there was no room to get a squeezer on the forward two rivets on both sides, so drilled 'em to #30 and used pop rivets. After the proseal dries, the rivets won't actually be needed.
With a batch of proseal mixed up, finished the baffles by adding a seam of proseal on the inside of the airseal fabric. This would have been way easier to do before riveting on the fabric.
