Man these are nice. Really looking good. @GregAlex, above you said... Quote:
The lathe work on these is outstanding! Lathe? I guess I'm used to a wood or metal lathe and I can't see how one of those lathes would have been used to create these... Can you explain? Thanks! |

The lathe used to create the image on the plate?

Perhaps. I am ignorant here, but I would not be surprised if some of those patterns are easier to create on a rotating cylinder than on a flat surface.

If you imagine the patterns made by an old Spirograph, that is the basis of a geometric lathe. These were first invented to do ornamentation on jewelry, pocket watches and things like Faberge eggs. But someone realized that if you engraved the patterns on to a flat metal plate you could then use it for intaglio printing as well. Here is an article and video about a rose engine lathe that shows it retty well: https://makezine.com/2018/03/22/beh...rose-engine/Edited by GregAlex
