Drilling left tank

Today I started with match drilling T-701-L to W-423, then removing the left fuel tank from the wing and final drilling all of the holes. The next step was counter sinking the T-701-L skin at all of the holes that attach it to the T-702 baffle. After that, I removed all of the clecos and marked the ribs and brackets, then fabricated the T-405 tank attach angles out of 2x2.5x3/16" aluminum angle.
