I made this nifty ring clamp for myself, after I saw a similar clamp being used by a
Russian master setter.
I have got the proper GRS inside ring clamp, but it only expands from one side. I don’t
like that much because it puts expanding pressure on only one side of the ring.
And anyway, there is absolutely nothing I like more than making gizmo’s and tools.
Components.
The center is a black nylon bush that has a cone on both sides.
The two brass cone shaped washers that force the nylon open when the two stainless
steel screws are tightened.
This stuff all turned out on my small Grizzly lathe.
Then, once you got the ring tightened up nicely the setting ball gets tightened and the
whole expanding ring clamp is held in place.
This is great for setting eternity bands, because once the ring is tightened, turning
the ring around is a matter of loosening the setting ball, not the ring clamp, as in the original GRS equipment.
As with a large part of the jewellery industry, the bar is constantly raised by new
techniques and methods that are developed.
The GRS system, a microscope and the Gravermax or Lindsay Air assisted power engraver
have become the accepted norm for those craftsmen working on a high level.
In the old days, I had a ring clamp, some gravers and a Optivisor and that was good
enough. These days the retailer wants stones set so that at 30 X magnification the job is flawless. That is not
possible with an Optivisor.
Speed and accuracy is what counts.
