Be careful here. The angle used in aircraft is quite different than
the angle commonly found in metal supply yards. Note the radius on
the inside -- a lot of the commercial stuff has a sharp inside corner
that IS NOT suitable for longerons. Even though it's the same alloy
and dimension, it will not work.
