Retirement comes sooner than you think !
.... Build up a reference Library of your own, take a machinist training program and learn how to run a lathe/milling machine. Then try to find work with an established 'Smith. 'Wish you luck ! .... none of the Gunsmiths that I've met or known, have done very well financially, even as a part time Pension supplement, considering the amount of capital investment involved, it's probably not a truly viable option. Maybe, just maybe, you could do the odd checkering or stock refinishing job. Those, while involving skills, aren't as capital intensive as 'Smithing. For retirement, depending on where you end up living, there's Blacksmithing and Farrier work. Check with your local Community College for Courses/Training programs. Believe me, it's good to plan for your retirement before you actually get to that point in life !!! ..David K.
