Nay, this was a noobie at work... The Sherline 10,000 rpm pulley set works very well. Burr free, or at least I don't feel or see it. Push the trimpot to max and went with 150mm/min feed at doc of 0.20mm per pass. Finishing pass at 100mm/min and cutting 0.1mm off the wall. Using air to clear chips with the air gun (handheld throughout). A little nerve racking but satisfying...
