I'm a fabricator, restorer, tinkerer, maker......My day job is making parts for antique machinery and locks.....

Fullfilling?

YES! been doing 30+ yrs.....I'm self employed, work in my own workshop, and set my own schedule....being its an odd skill set, I get paid well.....want proof? I do it as a hobby when not paid for it....lol.....I also do side projects like jewelry making, making special camera mounts, modifying fishing reels, etc....pretty much anything that requires machine shop work....

Benefit humanity?

I re purpose a lot of "junk" into my work....a small way of being "green".....the things I retore or fix will continue to be cherished, used and not in a landfill....
