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

A "Diamond" parting tool refers to the cross sectional shape of the tool
not the material from which it is made. See:

The "diamond" in the name refers to the shape of the tool shaft, not the
inclusion of any actual diamond material. A diamond parting tool has sides
that are relieved, resulting in a roughly diamond-shaped cross-section. The
advantages of such a tool are that only the side "points" of the diamond
contact the sides of the cut, making it much safer and easier to part
deeply. They are more expensive because of the extra machining operations
that go into them.

When you sharpen it (with exactly the same equipment that you sharpen all of
your tools), make sure that the point formed by the bevels on the face meet
at the side points, the thickest part, of the cross section.

When I play solitair with a real deck (not on the computer), the *diamond*
cards are much *harder* to deal.

L. L. asserted, "the diamond cards are much 'harder' to deal'.

...but they trump those from the deck when honing skew chisels. Does
Leo ever cheat Lichtman at solitaire? No! Never!

Look for World Championship Solitaire on your cable tv
schedule. If there isn't one yet, there will be. I found
a Championship Darts show while channel surfing. Can
Championship Solitaire be far behind?

Thanks for the information and double meanings. So there are diamond
dressing stones, diamond sharpening sets, diamond parting tools and
Bedans to contend with if you do woodturning as a hobby

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.
