Bill,

My guess is that the person posting this question was not thinking about
what we refer to as engine turning (like the design on the cowl of the
Spirit of St Louis), but what I would refer to as ornamental turning. The
designs are far more complex and were produced on rose turning machines and
Holtzapffel lathes. Here is a link to a site with some good photos of the
types of designs.

Interesting approach, hi-res images and use with DeskArt:

I have pondered how to program these types of designs and come up short. The
math is over my head. Would love to see a discussion on how to use a 3 or 4
axis CNC machine to do this type of ornamental turning.
