+1 Mikey. I think I can see what Chris was getting at, but Mikey and so many others here are nailing it. This surprises me because I got into this because it was the next step in the 30yr evolution of what I do and am surprised at the similar experience.
I tried to get by with what I had but it was either evolve or bail. It did help I had a lot of tools from being a mechanic, but machining is another bag. I've always loved making more than fixing. So I did a somewhat parallel to the original criteria and thought about the parts I needed to make. A mini mill and 7x12 lathe could do it. So I went the next one up, RF30 mill and 9x20 lathe. Both used and a little less for both than a HF MILL/Drill new.
This has opened up whole new horizons that no amount of research, forum crawling, and strategizing could have foretold. In some ways it's filled in the gaps in my skills as I learned just what was needed to be a mech, engine machinist and a fabricator/welder. But it's taken down those barriers that only being a machinist could get through. I'm also stunned by the amount of creativity it takes to figure out everything from the design, material, layout, metrology, setup and execution. Some would call it an addiction but the satisfaction of I couldn't make that before, and now I can is pretty powerful. And it drives me to the next level.
