Assembling the left tank: 6.1 hours

After strapping the tank to the wing I match drilled the tankskin to the joint plate. Then I match drilled tank skin to ribs and end ribs to Z brackets. Match drilled baffle to Z brackets. My Z bracket holes came out spot on so I am very pleased with this method!

Started match drilling right wing spar Z brackets while the pressure was up in my compressor.
