> Stopped by the local aluminum source to begin education on skinning Ruby.

> Big mistake! I needed to have graduated from remedial aluminum before

> experimental aircraft builders.
>
> Got a quick lesson on thicknesses, hardness scales, etc. They have rolls
> and sheets from .016 to .190 and hardness from H 14, H 32 and T3 alclad to
> T6 Bare. They also have stainless steel annealed but looks like you could
> skin in $20 bills for same price!
>
> For those of you ahead of me, what did you use? Do you vary the
> thickness... say between the quarter pannel and the door... or tub behind
> the petrol tank? Stiffer for door, say T6, and easier to shape H32 for tub?
>
> Thanks for anything you can share.
