Paper patterns have a useful accuracy of .010” on panels that have not had their surface areas manipulated, at least for me.
In my experience, using paper of certain weights has advantages in particular operations. Like re-skinning the dihedral intersecting panels of F1 wings, for instance It’s all bonded structure of .012” 2024T3 contact-adhesed onto a molded rigid foam core with a titanium inner structure. Light as a bag of chips and incredibly strong. The fits have to be dead on because you're bonding on a mirror finish
and you have to get it right the first time because of the dang contact adhesive.
(icon of sweating bullets
here.) Making accurate paper patterns and cutting the panels to the half-whisker are absolutely
de rigeur.
Good clear film of the essential standards, Mike.
