Lathe Tool Grinding Helper

This is nitpicking but the technique produces an approximate radius and would require quite a few passes to make it look good.  Time consuming when the mill spindle is stopped between cuts, as it should and which he noted.

Impractical for radii greater than about two inches (limitation imposed by the vise jaw dimensions).  Impossible for long parts.  Method always requires a hole for the dowel pin which is not always possible.
