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.

Child’s play
When you are a carpenter by trade with an interest in cars and still young at heart, making wooden toys has to be the perfect retirement occupation—although many of Alan Gray’s “toys” are not the sort of playthings you would put in the hands of small children. His meticulously crafted vintage vehicles, fashioned mostly from native timbers, mahogany and macrocarpa, can take around 60 hours to make and are more collectors’ pieces.
To keep the real kids happy, he has a more robust range mostly made from pinus radiata— diggers, trucks, pull-along hippos and the like.
Alan, 71, and his wife, Lesley, have been living in Cromwell for the past six years. Originally from Dunedin, Alan trained as a carpenter but turned his hand to fishing after moving to Stewart Island. He then spent the best part of three decades skippering boats for the Department of Conservation.
