WorkSafe NZ has contacted The Shed and advised us of two recent deaths of New Zealanders using a Lichtenberg wood burner. They have advised us that these electrical devices are not safe to use and are dangerous.
Do not build or use one of these machines under any circumstances as they are unsafe and can cause fatal injuries.

A butterfly takes wing
This simple butterfly pendant or brooch (depending on the back fittings) is a very good exercise in several basic goldsmithing techniques. It also can be decorated in several different ways to produce strikingly different finished pieces of jewellery.
I drew this design more than 25 years ago for a company that then made paua-shell jewellery. They stamped out their products, so I often made the master patterns in copper and from these patterns they spark-eroded the dies.
If this design was being made in an art school, it would be stuck to a sheet of silver and the basic shapes cut from there. If a design was made this way in, say, 18-carat gold and the wing outlines (as here) made from 2.5 mm thick metal, the outlay and waste material would be considerable from a 2.5 mm-thick sheet of 18-carat gold plate. But we will make it like a professional craftsman who has to live in the real world where costs matter.
