Very short build session in the garage tonight. I fiddled with the fit of the 2 centre floor stiffeners. Tried to get that joggle bend sorted so the skin sits nicer.
I then drilled the remaining holes in the stiffener.
Next I need to drill the #30 holes in the vertical portions of the stiffeners, but the area is too tight for my cheap 90deg drill kit. I will see if I can borrow my buddy Mike's 90deg pneumatic drill to finish this portion.
