Task: Fabricated the T-405 bracket, fitted the flop tube, and drilled the tank access hole

Today I finished fabricating the right T-405 attach bracket. It will eventually be drilled and bolted to the fuselage to help support the front of the fuel tanks. This right one is slightly different than the left in that it will be used for aerobatic flight. To allow this, the fuel pickup must be able to get fuel at any aircraft attitude. A flop-tube is used to accomplish this task. Instead of the fuel pickup mounted on the access plate, the flop-tube is mounted to the front of the tank, and allowing it to have unristricted access to any part of the first bay in the tank. Once the flop-tube was test fitted, I cut the tank access hole in the inboard rib and drilled the nutplate attach holes.
