Hey John, Since I was testing an ELS software tutorial I thought I'd grab a scrap of something that is very rusty. I faced it off at 586RPM. Then turned it at 586RPM. It's about 0.84" diameter and SFM reported by the ELS was 132, First pass 0.008" per rev and 0.010" depth of cut. Second pass 0.003" per rev and 0.003" depth of cut. You can just spot the carbide insert underneath the rust dust. It's very smooth. Wouldn't take much to polish it. http://www.autoartisans.com/Lathe/SmoothTurning.jpg
