Shaping the inside of a ring - Tools

[deathruddles]

Hi All,

Relative newbie here!

I'm in the process of making a court profile wedding ring in 18ct red gold.

At present everything I do is hand shaped from rolling mill square section.
The outside of the ring is relatively quick to do with pillar files, but the inside... that takes a while!

Can anyone recommend a mechanised way of shaping the inside of a ring?

Many thanks
Nick

If your OK filing the outside, file the inside also by using a crossing file, like this one; http://www.cooksongold.com/Jewellery...prcode-999-477

Hi James,

It's too wide for this particular ring, (Size H!)
I've just ordered some of the rubber cylinders, Eveflex-Rubber-Burr-510-Blue------Coarse-On-A-2.34mm-Shank-prcode-970-350 (CANT POST A LINK YET)
Hopefully it'll work...

There is a narrower version, the 4 inch Vallorbe crossing file which is only 12 mm. at the widest and would be OK on the H size ring which is 15mm. interior diam. See; https://www.eternaltools.com/precision-crossing-file

I use Cratex wheels for finishing.

Cheers James, I'll try that one if the rubber burrs end up not working.
I'll see if i can find a cut 2 version though, cut 4 might take a while.

You can't have too many tools, I am a bit shocked at the prices these days, I am still using files I bought 35 years ago.

The risk with rubber burrs is getting an uneven finish, use a cylinder shaped burr, that should help
