How hard is it? I have found that harder steels give a better finish anyway, and with a small cut and a huge surface speed CBN tipped inserts work nicely. You probably want to use a tailstock for rigidity. Look at Youtube for examples of "hard turning" and eBay for individual inserts. -- atp The idea that there is no such thing as objective truth is, quite simply, wrong. ------------------------------------------------------------------------------ Keep Your Developer Skills Current with LearnDevNow!
