From what you have written it seems to me to be rather a large
quantum leap for you from wire wrapping to a full on PMC ring making
To give you an analogy, how many years of learning does it take to
be able to sit at a piano and interpret Chopin’s revolutionary study?
you know the answer as well as i do.
So, there is no quick or easy way to do what you want yourself.
In fact you mention design, well, this in fact only becomes possible
when you have mastered the practical techniques of what ever you
want to make, in your case PMC. Design is always limited by material
in any case, PMC might not be the best way forward anyway…
Therefore you will as others have suggested, take a course somewhere
to look at the basics, then put your hand deep in your pocket to put
together all the tools, furnace etc to start.
You will find it a frustrating and steep uphill path, but with
determination you should get there.
Then, when you have made lots of items and more failures youll be
ready to make the ring with the stone you have purchased.
As to mounting, once you have reached this stage, well look at the
various options of doing this.
there are several simple ways, but ist things first. Get back here
when your ring is fired and ready for setting.
