So I have a degree in Mechanical Engineering, access to a machine shop, and all the free scrap metal I want (steel or aluminum mostly). I also make perilously little income because I'm just a measly intern. I have a stash from my last job that is keeping me running until I can convince my employer to hire me on full time, but it's quickly running out. So I need some extra money. The question is, what on earth do people need fabricated? My first thought is tools. I'm currently building a combination drill-press/milling machine that could be converted to a saw if need be. I could also get a chunk of steel and make a hammer or chisel or even a screwdriver. Any other ideas? Anyone know of a good market to get into?
