Bulkheads and Longerons Match-drilled

I didn’t get a ton of time today to work, but I did get all of the mating surfaces inside the plane match drilled. I got the shims fabricated for the trailing end of the top longeron to skin so there’s identical thickness of skin and no odd pillowing of the skin when I rivet it. I got the top skin mounted so that I can match drill the external skins tomorrow. Once that is done I’ll have to pull this apart to deburr and dimple and then reassemble it for the last time to rivet it together.
