Hi Gravers,
Standard ring jigs that are used to engrave the sides of ring always
loosen up. I find this annoying. You can only engrave in one direction,but
this tends to limit design. You can mount it in dop with your choice of
holding agents; diamond cement, shellac, etc. This is not always an option. Some stones simply will not take the cleaning process.
The idea is to have as many options as you can, to hold a piece of
jewellery to be engraved.
The solution I came up with is a simple jig that does not come loose
because of vibration during engraving using power assisted tools.
You do use some of the standard parts of the a normal jig.
The screw, collet, and expansion cone. You also use two nuts.
Why two nuts? The second nut is used as a lock device, that will not
allow the jig to loosen while your engraving. You can use two nuts of the
same size. I like using a "rod connector nut" that allows me to raise the
ring in the positioning vice. This makes engraving more comfortable.
See the pictures on how it works.
This works for me, very well and I hope it does for all of you.
