Machining 4140

You're probably not going to be able to take anymore than .050" DOC (Depth of Cut) and possibly only about half that amount.  Do you have access to another lathe that can take a deeper DOC?  If so rough it out there.  BTW, you'll want to finish it mounted on your spindle to make it as true as possible to your machine.  Also use a center punch to show its mounting position.  I always make 4 little center punch marks to show alignment/location on the spindle nose.
