I finished de-vinyling the right fuel tank skin.
There’s not much to see in this picture, but I match drilled all holes on the skin, ribs, and baffle.
I countersunk the holes on the skin that interface with the baffle. I was only able to cut the holes on the top side of the tank. I’ll do the bottom side next time. Since I’ve done all this work on the left wing, everything is progressing faster on the right wing.
