Casull, no discouragement intended.
Many guys figure they can get into the trade with little investment or training, and still make a living. To start up is not easy as banks and insurance companies do not like us. Education in the US is VERY expensive for anyone from a foreign country. Machine equipment is not cheap either and the specialty tools alone will cost thousands of dollars.
We need more compentant gunsmiths, but gun owners and gunsmiths are a dieing breed, I think due to a changing Canada more than anything. When the east elect the Liberals again it will continue to decline.
I would just like to add that during the two years I spent at gunsmithing school in Trinidad, Colorado I was taught the basics in gas welding, lathe and milling machine, etc, metals and heat treating, metal working (forged and made stockmaking chisels and gouges and smaller wood carving tools and checkering tools), taught how to inlet and shape a stock blank and finishing and how to checker and carve, how to thread and fit and chamber a barrel, choke alterations and shotgun barrel work and more. All the basics to make a custom rifle using an existing action. On the side I learned a bit about barrel making and made a rifle barrel at the home of one of my instructors. I also worked a bit in New Mexico on weekends at a reamer maker helping out. I picked up enough knowledge to know I did not want to make barrels or reamers. On top of that we had some practical gun repairs on common firearms taught and reloading. On graduation you have a lot of experience to start but you need a lot more.
I got a job as a gunsmith in an existing very busy firearms business that had some tooling. I worked as a store clerk as well. I gained a tremendous amount of knowledge over the next ten years repairing commercial firearms and doing a bit of custom stock work and rifle building and my skill developed to a fairly good level. More money is made in repairing and simple jobs as scope mounting, recoil pad installation, and fixing broken guns and cleaning them than in custom work. Sure it is nice to build a fine rifle, doing the precise metal work, flawless blueing, and custom stock with fine checkering and maybe some carved patterns and get the praise from those who appreciate the skill and effort spent.... but it is not what puts the bread and butter on the table and it is easy to get burnt out on doing the labour intensive work for others.
Eventually you save a bit and buy tooling as you can and eventually you can have a big investment and gunsmith full time if you have a paid off mortgage and a wife working too. I forgot to mention how expensive it is to raise a family.
