Saw a video from Joe Pieczynski about turning ultra small diameters in one bite and thought useful for turning valve stems.
Current approach is to whittle down to size with small amounts of overhang in a series of "moves", extending the raw material perhaps 3mm each time.
Takes a long time per valve stem, so asked about the tool he used which appears to be no longer made.
Query would be, any details available on the holder/tool bit setup so one could "copy" or make one's own tool to...
