    Mar 01 2010 · Like Mickey D says copper can be a royal pain to deal with. We used to run a lot of 1 1/4" round bar in the CNC lathe at work. Problem with copper is that it is SOOO malleable. It flows nearly as much as it cuts. You could make a threading pass and sometimes it would actually INCREASE the outer diameter as the metal flowed around the tool.
