May be these bureaucrats in FTC do know something, after all. I do
not want to put Charles on the spot, but sometime ago I issued a
challenge, which he accepted - to produce eternity ring like it
depicted on my DVD, by any technological means: CAD/CAM, casting,
lasers, anything at all. It has been a few month and apparently he
is having some difficulties with it. The challenge still stands.
Use any technology, anything at all to make the ring of equal
weight, equal strength, and equal appearance. Give it a try and the
difference between primitive hand made versus wondrous, awe
inspiring, technically superior casting becomes apparent. Leonid

Think nothing of it Leonid,
I accepted the challenge, noob though I am, so I’m not being put on
the spot.
I’m still working on it, amongst other things, but I wanted to keep
it fun, so I’m not busting my balls.
The difficulties I’m having are as follows :-
-
I’m using Lightwave to make the models, and converting them to an
.STL format, I am getting conversion errors. If I were using Rhino,
I would be suffering less. But I want to use what I have available.
-
I’m using Lightwave in ways I have never done before, so there’s
a learning curve. Usually I make very different things with the app,
and do a little compositing.
-
Finding time amongst the day job, study, children & SHMBO.
-
I have a general level of inexperience in the jewellery trade,
but I’m learning, so these problems will lessen over time.
The progress thus far is that I’ve managed to make the channel
section of the ring, and due to lack of experience I haven’t found
the best way to make the fish tail section. I’m taking the channel
section directly to the casting house tomorrow to see if I can figure
out the conversion issues (it may come down to the fact that I may
have to buy a student copy of Rhino).
I was thinking that the wax printing would be substandard, and was
about to admit defeat, as I had only seen images of the printing, and
they looked awful. However 16 micron printing is very smooth, it was
just colour variations in the wax layers that made me believe
otherwise.
So from this technology, I will be able to produce Leonid’s ring,
and it’s properties will be as follows :-
It will take a polish, the level of which I am yet to determine. It
may not take a polish as well as a hand wrought ring, but I’ll give
it a go. It will have the same shape, and dimensions (or as close to
as I can figure out from the picture supplied). It will be able to
take stones, they have done this already with traditional casting
methods, and the wax printing seems to be the same.
What the ring will not have is the work hardening that comes from a
hand made ring, and I know this from the get-go.
For me it’s an exercise to see if I can. If I can’t, then I’ve still
learned something, and share the results.
I’ll keep you posted.
Regards Charles A.
P.S. I did a casting experiment the other day using lost foam and
Freeman’s Fillet material. So cool, much faster that investment or
hand wrought, but that’s for another post
