Pretty much a repeat of Friday but with the left tank. I had not previously edge finished the baffle like I had on the right tank so I did that in conjunction with de-burring the baffle prior to drilling the stiffeners.
I fished out the T-410 rib tip doublers, cut them out, and edge finished them. I then used the T-410 to trace an outline on the T-405 to capture the shape to fit inside the rib nose.
