Vern, if you want to be a..........................
gunsmith, find out if your local community college has a machinery program, lots of guys do that, and learn to run machinery and think about how YOU would do something that you've picked up to admire.
You might also think of learning to do programming for a machining center, since CNC is doing everything right now.; especially if you have a new gizmo guys want, or, you could farm it out.
But, another thing to think of is, after the feds, the state, the county, the city, and the township (if there's one) finishes being a PIYA, then they like to line up like buzzards, to take a piece OUT of it. And they get those jobs, because somebody gives them POWER, and because they don't want to work....and they don't care if you want to.
Its a JOB, to most gunsmiths, I mean, guys sit down at the range and think, "I'd love to do this ALL the time." But, when you become a good gun-SMITH, you mostly cease to be a good gun-SHOOTER, because you just don't have the time to shoot.
If you go the comm. college route, you can learn all kinds of things, even basic business accounting, and you can work on projects you want to do, since many of those schools have a limited curriculum, and if you're bringing in more esoteric projects that aren't necessarily gun-related, but complicated, they'll let you do them because you are refining your education.
Or, you could go to Ferlach, Austria for four years and get a real education in firearms....
But the one thing to remember is, the things YOU decide to work on, can be fun for YOU, and YOU don't have to make money by working on them, for anyone ELSE.
Didn't want to rain on your parade, but if you want to do it, do it, just don't HAVE to do it. Have something else, waiting in the wings...
