I have a CNC drill/router at work which was originally intended for printed circuit boards.
I have made a few camera parts on it for myself from 1/8" thick laminated material.
Most of the parts for this were cut with it: http://www.geocities.com/steve.smith...et.com/cam.jpg
Unfortunately, I can't cut aluminium with it... yet. I need to find a way to slow it down. You end up with a molten mess at the cut edges.
I am going to try brass soon as I think I may have more success with it.
