I love that you actually make stuff. I have only done mostly replacement of things, never a real "build" like you have going on.
You are making a one of a kind bike. That is great.
I especially love the "the painter will fix it. Oh wait, that is me!" What you plan or don't plan does come to haunt you down the road on projects. Decisions made now impact greatly the choices in the future. I can tell you have the mental wheels turning and I am excited to see what you come up with. it isn't just a build, it is a masterpiece.
