Scorch, you are correct. It has taken me two years of learning to realize how much I don't know (sounds like Socrates might have said something like that) and I'm graduating in a few months. The school opportunity truly gives you just enough time to start learning equipment and understanding the bare basics of many broad types of work. I know many graduates of various schools who thought their learning was done and now unfortunately call themselves gunsmiths.
Unfortunately, it seems the number of people who want to become gunsmiths outnumbers the educational opportunities available and many are unaware of the level of their own incompetence or inexperience (Dunning-Krueger Effect).
