I began the session by finishing the T-405 tank attach bracket. First I adjusted the fit, then marked the location for the six rivets that attach the bracket to the rib. After drilling, I then clamped the reinforcement plate that fits on the inside of the rib and final drilled #30. Then, I used a fly cutter to cut the access hole in the inboard fuel tank rib. After cutting the access hole, I smoothed the edges, then began the process of aligning the reinforcement plate and cover to the access hole.
