Wow! Sounds like you know your way around machinery. I'm just an old putzer but I agree with you about the regular drill press being an indispensable tool.I do a fair amount of welding mig and tig those old gas welders are the best nice and clean DC. I used an old Lincoln at one of my jobs it had a straight 6 450 amp I wish I had that machine around today. Being retired I don't do much heavy stuff any longer so I guess I am good with what I have. I can build most of what I want. For Roofner this is the kind of portable drill press we had when I was still working. Hougen HMD904 Portable Magnetic Drill But I still wouldn't be with out a regular drill press it is a very versatile tool.
