Wanted to finish the parts for the fuel tank today. Drilled the stiffener to the inboard rib. Dimpled the rib and countersunk the stiffener. Attached the nutplates for the coverplate. Also attached the antihang bracket on the inside of the inspection plate. Went ahead and torqued the flop tube pickup weight to the line. Torqued it to 110 in pounds. Spent some time making the flapper door for the second rib. don't want the fuel draining back out of the first bay during aerobatics. Alot of tweeking but came out fine. the rivet pattern is kind of weird due to the groove in the rib. No weight on the door so it will work just fine. Made the support bracket for the vent line.
