    Default Shaping the inside of a ring - Tools

    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.

    For someone like me, who likes a perfect profile, but was not brought up in the trade, the resource of choice would be an oval draw plate. The leading end can be tapered in the mill to further avoid filing.

    Failing that I would use the D-wire extension of my mill and just bevel the inner edges to make a fake court shaped ring. Not against the law-yet. Dennis.

    Hi Dennis,

    I was debating using the D-wire ext rollers on my mill, i wondered what might happen if it was passed through twice, one time upsidedown... might get the approximate shape and make filing easier.

    I forgot about draw plates! that probably would be much better.

    Quick question about draw plates... I have a very cheap ebay draw plate, it keeps grabbing the wire and snapping it even though i'm lubricating with B-wax.
    Is this just a draw plate thing, or would an expensive draw plate help?

    Are you annealing the wire, it. May just have become too hard and brittle so will snap?

    Hi Caroline,

    Yep, it snaps straight after annealing.
