Do you remember what you did to remedy the situation as you were planking the fuse? I was thinking that I would inpart a gradual taper from the last correct former to the tail and just build-out the incorrect formers to fit, although I am not sure it this needs a more parabolic contour or if a straighter profile would be closer to scale.

Osman, I will PM you to get your rib .pdf file. I still am undecided as to whether I will do the sandwich method or if I will cut out each rib using somethng like your auto cad design.

I'm almost done with the armoire I am building for my wife, then I can devote even more time to this
