I have learned the hard way with this project that practicing a new skill on actual airplane parts can have bad results. Sometimes these bad results end up with replacement parts being shipped from Oregon! Lesson learned, always practice a new skill, or knock the rust off an old skill, by practicing on scrap parts. Because I didn't learn this lesson until a ways into the project, I now have a "scrap parts" pile a little larger than I would like. Well, I have put my "scrap parts" to use as practice material and now have a work of art to show for it.
