I think this is correct, but there is a proviso that the part you are
fabricating is not available.

On one hand, it's not that complicated. There is no proviso that the
part not be available through normal channels. On the other hand,
you must have some justification for the part you manufacture. It
generally is reverse engineered from the original. A stainless spar
(or wood or carbon fiber) would not fit that. What we have here is
major material substitution. Once you manufacture this part, you
need to install it in accordance with the FARs. That means an A&P
and in this case an IA have to sign off on the part being suitable.
Good luck without a major engineering study. Oh, then it also
qualifies as a major alteration (the installation, not the
fabrication) so you need a field approval...
Other than that, no problem...
