I think you can build a plane of WOOD from scrap, if you know what your
looking for and oversize questionable pieces, but the Zenith line uses the
thinnest aluminum I have ever seen on a plane, and I agree it's critical to
use metal at least as strong as the 6061, and only if it is heat treated to
the proper levels as this makes a big difference in the strength as well.
If you go with 2024 aluminum, you have the corrosion problem to account for
as well

Bob,
I agree. However, I don't think this young man understands the serious
nature of this project he wants to undertake. 1) Building an airplane is
absolutely not like building a kid's pedal car from scrap aluminum, 2) An
airplane design is a VERY complicated thing, not to be "thumb-ruled" or "by
guess and by goshed", 3) Unless it is the proper alloy and temper (6061-T6
or 2024-T4), scrap aluminum has no place in an airplane, 4) simply
oversizing does not ensure safety, 5) a haphazard approach to constructing
an airplane can result in DEATH.
I feel that Steven's approach to this project is MUCH too casual and is
potentially dangerous. I am afraid for him.
I would like to encourage Steven to do some serious study and investigation
about airplane building before attempting to build an airplane from a
tattered, out of date, partial set of design drawings, trying to guess at
the missing parts and adlibbing with available materials, simply because
they are available.

I'm sorry, but sarcasm doesn't convey well in text. We have a naive and
confused young man who would very much like to build something and I would
hope that he might get some useful advice but, at worst, he shouldn't be
made fun of.
