Making the Diamond Spangled Bangle -- 3

Setting the stones. Setting in the stones.

To flush set small round stones I'll start with a hole slightly smaller than the diameter of the stone. Then create a "seat" for the stone with a bearing bur the same size as or slightly smaller than the stone. Burnishers can be made from old burs held in a pin vise. I burnish with the side of the tip, moving it in a side to side motion, exerting enough pressure to upset the edge and move metal down toward the crown of the stone. Smaller diameters will move more metal and are useful for getting a stone tight, larger diameters might leave a smoother surface. It can be useful to have a couple diameters at hand.

The mold has been opened and a wax removed. The pieces are in front of a wax injector which holds wax at an optimum flow temperature. A compressor supplies pressure, usually in the range of 7 to 10 lbs depending on the mold. To inject wax into a mold, the assembled mold is held in hand between two plates. The opening in the mold is pressed against the nozzle of the injector -- which is spring loaded, and wax flows into the mold. At the low pressure used, it will stop flowing when the mold is full.

To follow-up my previous post I thought I'd show a few photos taken while the bracelet was being made and comment on some of the techniques used. This piece was made for a jeweler whose customer had a link bracelet I had made. After being worn daily for many years it had simply worn out. They were considering having it remade, but decided upon resetting the stones into a hinged bracelet with a similar design.

Simple Hinged Bangle This is a simple hinged bangle I finished up a few days ago. Instead of carving the piece in wax or forming it directly in metal I modeled it in the Rhinoceros CAD program and had the main form built in resin on a 3d Systems ViperSi²

I managed to take a few photos while building the piece and will try to follow up with a post on the process.


New discovery -- The Staffordshire Hoard

| |

As long as I'm on a posting binge ...  This may still be news to some here--it was news to me. There was an incredible discovery of Anglo-Saxon metalwork made recently, July, 2009. Over 1500 objects, 5kg of gold work and 1.3kg of silver. They've put up a nice site, http://www.staffordshirehoard.org.uk/, with over 600 images of items found. The image above is used courtesy of the Staffordshire hoard website.


Very Hasty Tux Studs


Fairly Hasty Cufflinks

The morning of the one day I wore a tux I realized I didn't have cufflinks. These are what I came up with. They are scratch finished, oxidized, sterling silver with 14 kt. yellow accents. The back side simply has my logo stamp for decoration.


New campaign to make 9/11 wreckage available.

I caught an interesting article In the New York Times this morning that also kind of surprised me. The New York Port Authority has pieces of wreckage from the World Trade Center available to civic leaders for use in local memorials.

Who would have thought?

A blog? I'll try not to make this first entry my last.
