So I'm working on a project, and I need small pieces of steel machined to certain tolerances. I'm working with a machinist friend to build a prototype, but if this idea (which I'm keeping to myself at the moment) takes off, I may need to have a number of these pieces made. I'm not expecting to start a business or anything, but I could see selling a dozen or two. He's taking time out of his day to help me out with the prototype, but he won't have time to machine a bunch for me. Stainless steel, if it matters. So does anyone have any input as to how I'd go about contacting an individual or company that does small-batch milling and tapping?
