I got a moderately prices diamond parting tool from Penn State
Industries. Up until now I have never tried to sharpen it but rather
rub both edges on sandpaper lying flat on a workbench. When I hear
diamond I think of something harder than a grinding wheel. Does
anyone know how they make diamond parting tools (micro diamonds in the
steel I assume) and if how they are made makes any difference on
sharpening them? Thanks and Happy New Year

Tips fer Turnin': Place a sign, easily seen as you switch on your lathe, warning you to remove any and all rings from your fingers. Called degloving, extended hardware can grab your ring and rip it off your finger. A pic for the strong of stomach: www.itim.nsw.gov.au/go/objectid/2A3AC703-1321-1C29-70B067DC88E16BFC/index.cfm

Besides, rings can easily mar the surface of a turning as you check for finished smoothness.
