Thanks for the advice. I knew milling was the wrong term when I wrote it but I couldn't articulate what I wanted to say. Drilling metal was a better term, although I did think about cutting down aluminum pillars. I always prefer to learn from other peoples mistakes.
I move a lot with the military so I can't set up my final shop yet and need to keep things lighter and smaller. I'll keep hunting for a used one and hope I get lucky.
Thanks again.
