This is the first piece of Jewlery I have ever made.
11 months ago it was my wife’s 30th B-Day, I needed to do something special. I’d found a nice sized Garnet in Hart’s Range, Central Australia not too long ago and had a nice stockpile of Gold I’d gathered prospecting over the years. The stone went to a professional cutter, the rest is upto me and YouTube.
I designed the ring on Fusion 360, carved it out of wax using a Dremel, seal pick and scalpel, then made a mould of it using food grade liquid silicon. To make copy’s I used a large syringe in a metal cup with injection wax and filled the mould by hand.
I built a furnace using a 20L oil drum lined with Ceramic Wool, the heat source was an Oxy/Acetylene heating torch sticking in the side temp controlled manually with a laser thermometer. In this I refined the raw Gold with a crushed beer bottle and borax, then Alloyed it with Fine Silver and Copper.
Next the vacuum casting machine. A plate of steel, some air line fittings, PCV pipe, Silicone, Perspex, and a Automotive Aircon Vacuum pump borrowed from work.
Heat mats for the casting was made with high temp gasket goo squished between two bits of Perspex and glad wrap.
I casted using my backyard equipment, polished, set with a hammer and block of wood and this is the result.
