was getting some (seemingly) random results when playing about with an old rod from a ram - not spent a great deal of time experimenting but something I noticed...when moving the crossslide in and the tool first touches the work it was nice and shiny...after starting to move the carriage towards the chuck could see the shiny finish getting dulled down, this was hand-fed at various speeds, is that the chips getting caught between tool and workpiece and rubbing?
going faster (left to right) actually seemed to get a better finish sometimes...but at the same time going really slow sometimes worked
