Hi Hoyt

I've just come across some info on turning a hex or any other polygon on a
lathe.
It consists of a secondary spindle mounted parallel to the C axis and rotating
in the same direction. On this spindle, is mounted a side mill with two, three,
or four carbide inserts fitted. The C axis and the cutter are geared together,
at a ratio chosen to give the desired number of flats, and as the spindle is
traversed along the Z axis, a polygon is cut !!
I have details for a device to fit onto a turret mill, and a diagram for a CNC
lathe application.

Those caves of yours sound interesting. I must drop in sometime.
