Assembled fabricated L-angles to the F-728 and -729 ribs, then clecoed those and the F-706 bulkhead parts including the F-730 reinforcement plate, then riveted everything. I did drill a botched hole where the manual trim cable is to go if not using electric - I was going to use it for a wire run, but later elected to move over lateral. I will need to pierce the baggage floor rib later on, but fine with me.
