Guys I know there is so many variables when it comes to a question like this but maybe an answer will help. I am running the lathe at 250 then tried 400 rpms but just didn't help any.After each pass the finish looks like a pinwheel finish.I am hand feeding at a slow rate and very small cut maybe .002 you know just enough to clean up.My cutting tool is made for SS but wondering about rpms if that is where my problem is.Guy when I cut these these disk which is 1.5dia I am getting a better finish when cutting on the bandsaw.Thanks for any guidance
