Well, lets see, this was my first grip turned on my new Ryobi Mini Lathe....the grips fit on a standard pen mandrel which works out great. Folks, if I haven't mentioned it before, do NOT buy a cheap, no-name lathe on eBay!
I also tried a neat idea on Ken's diamond wraps...I bordered two adjacent sides with black thread, one side with gray, and the other with white. The result was that the diamonds got a slight bit of "3D" shading added to them. Very subtle, but it is noticeable when you really look at it.
