The HNT Gordon Planes are known for their use of Gidgee (Acacia cambagei, A. pruinocarpa); an endemic tree of Australia. It is an extremely dense hardwood, just shy of Lignum vitae at Janka Hardness of 4,270 lbf. The combination of Gidgee and brass is a hallmark of HNT Gordons Planes. Below is a short description Terry Gordon put together that describes the varying types of woods they use in their planes.
