Yep. He makes his living running a company that mainly does iron work (decorative custom fences, large decorative entry gates, custom kitchen vents, occasional decorative artwork and fancy stuff like that), but he can and does work with any type of metal: aluminum, brass, silver, steel, copper, etc., and makes decorative knobs, hinges, drawer pulls, whatever. He also teaches at a local University.

Just like the guy I took the course from is employed as a mechanical engineer.

The point wasn't what they do for money, it's what they have the skills to do.

The master cabinet maker I took my course from doesn't make his income teaching classes--nor did the apprentice cabinet maker who volunteered to help out every class for no pay.

The guy I was learning from left the US after coming home from Viet Nam, moved to England and spent several years completing an old fashioned, old-school fulltime apprenticeship over many years. However, a wife, kids, and the winding road of life meant a change in career.

The point I was trying to make was that the knowledge and ability is out there. Probably right down the road.

Anybody who would want to build one-hitters for profit, doesn't have the skills to build one-hitters for profit. If they did, they would be doing something else.
