Hi Chris,
Fantastic work (the norm for you!)
I see the pic of your webcam for $50 along with the several magnifications.
What brand is that?...And has it been highly modified to suit your purposes?



Thanks,
John Meissner (Bloy)

been a bit since i posted guy, sorry. been busy'ish.

I had a nice project to work on here.. saving grannies ring.. this mount is super old. the stone is unrecognizeable cut too. im guessing some windowed rough.

Doing a job which has this much sentiment and very littel actual design characteristics left is always shaky business.. Granny will remember it like the day she first got it, and you need to try live up to that...


wisps of original ring supplied



grab decent picture if possible



bring into Rhino and orient it as best as possible.



adlib the design around what little we do have.



layout for milling.



milled wax.



Cast model.



Some assembly required



and model assembled.




a few before and after shots..

Wow. Great work Chris. Being an older ring, was the amount of original detail considered to be high for the period?

hey guys, thanks :)

those pieces typically were stamped and assembled. its possible it was hand pierced but unlikely. the level of detail in jewellery has actually gone backwards over the last 20 years. simpler stuff, with cleaner lines seems to be more the order nowdays. But, i service top end lines so in my workspace typically 99.99% of the ring is all about the stone and only marginally about the ring itself. back in the days when diamonds were scarce this was the reverse.

Chris,
As always appreciate this thread and the work your do.
I just went over this whole thread searching for some info since I just started fooling with 3d machining.
Now i have an even greater appreciation for the micro work your doing and the equipment required to do it.
Thanks,
RICH

BTW, My little mill can only run  4 IPM, guess i will be doing a lot of reading. ;)

The videos he made are worth watching, too, if you get time.
