On the other hand, were it me, I'd hit it with whatever would cut it, then face it true on a lathe. Even a home-shop grade machine should be able to handle facing it. Parting is a whole other story.
OK, shows you why I outsource machine work. My local guy has a nice Hardinge(think 12" swing) and a big old Pratt and Whitney in the back(18", maybe even 20" swing) I just drop the stuff off and tell him what needs doing S/F....Ken M
