I have been known to produce some fine art in my lifetime from painting to carving , 3d drawing by hand and am very skilled with with my hands and intricate work. I once won my friend's company a 1/2 million dollar contract by freehanding all the 3 dimensional drawings for the project submission. I am very skilled at translating my mental vision into a finished piece and have done so in carving stone, crafting rifle stocks and assembling firearms and other forms of art and fabrication. It makes sense to look at the jewelry trade that is a good lead.
I'm disabled and want to take on learning a new skill I can do sitting down hehehe
cheers.
All the Canadian gun engravers that I have met have been self taught. They usually start with screw heads and simple projects like recutting worn engraving. If they get good enough they would pick up small jobs from gunsmiths. All started it as a hobby that became a paying hobby as their skill advanced and a very few manage to turn it into a livelihood. The greats like very distinguished Canadian engraver Heidi Hiptmeier all started as a beginner once upon a time. I would think the learning process would involve years of practicing on your own and friend's pieces to advance your skills to the point where someone believes enough in your work to actually commission you to work on their pet gun and pay you for the work. There are a few good books on engraving, most have some good patterns of various complexity. I guess you'll never know if this would be for you unless you try it but like most things don't expect to be an immediate success.
