How do they do this?

Hi all, Im Walt and Im new to the group. Just wanted to introduce
myself. I’m not a pro, just a budding hobbyist, but I figure the best
way to learn is read what the pros have to say.

I do have a question about one thing though, I was wondering if a wax
sculpt and spin casting would be the best method to produce a ring
like this… http://www.sganoksin.com/ftp/R-RBN11G-2T.jpg

However I want to put in actual letters instead of roman numerals.
Im in the process of copyrighting a design similar to these but
entirely different at the same time.

Any advice? This will be my first cast ring, so I want to make sure I
doit right. It will be done in silver or electrum.

I have made rings like this using photoetched magnesium plates made
for printing. If you need instruction, email offline
