[Ed.- read more about this and other Australian Tonewoods in Jack Spira's upcoming article... ] Natural History Australian Blackwood is a fast growing evergreen tree wiith a native range in eastern Australia. It can age to 50 years and attains heights of 45m in the cooler rainforest climates of Tasmania but can tolerate urban, poor soil and water conditions very well. It is an important horticultural as well as timber species in Australia but is known to be an invasive one in others. Oregon Mrytle is a distinct species from that mentioned in the Bible. It’s pungent leaves has a similar flavor to bay leaves and can be mistaken for Bay Laurel. Status J.Spira GuitarJack Spira Australian Blackwood A highly figured Australian Blackwood set on a Spira Guitar. Within it’s native range, Australian Blackwood is widely exploited for it’s timber. The older, figured logs are now rarer but a good supply of the younger trees will continue for time to come. It has been planted as an ornamental as well as a timber species but has several draw backs. 1. It often damages undergoing piping and paving 2. It can invade local habits and force out native species. Wikipedia writes:”It is a declared noxious weed species in South Africa. It was also recently listed by the California Invasive Plant Council (Cal-IPC) as an invasive weed that may cause limited impact (Knapp 2003).” Physical properties The heartwood is golden-brown taking on a glow when finished. It can display fiddleback as well as colour variations. Australian Blackwood has a Janka rating of 1270 and a Specific Gravity around 0.6. As a tonewood… Melbourne based luthier, Jack Spira says: “It bends very well, although care is needed with the highly figured boards. Its stable enough to be reliable in service. I’ve not found it to be super stable though, so I’d say its important to get it well quarter sawn, and I tend to avoid using it for necks.” Subjective tone… J.Spira GuitarJack Spira Australian Blackwood A highly figured Australian Blackwood set on another Spira Guitar. This one features a highly figured spruce top some call “lucky 12″ check out the entire guitar here. I feel that the tone is very very similar to Koa, which a woody, open tone somewhere between mahogany and rosewood. Jack Spira again:” How it sounds is a very subjective thing! To my ear, I think it tends to have a fair few high overtones, giving it a dry, sometimes reedy or breathy sound if that makes sense.” Availability Figured examples are getting rarer and hence more expensive, but supplies of younger growth look to be good for the near future.

You should rename this to Black Acacia, and add an "aka - Tasmanian Blackwood or Australian Blackwood, depending on the source". |

Bob, we could certainly get into a semantics argument here, but the most common name outside of Australia is Black Acacia, derived from its Latin name acacia melanoxylon. This is the name LMI has used for well over ten years, and the most common name at least on this continent. I would argue that Australian Blackwood is more of a regional name. But whatever....it's just not that important to me to type any more on the subject.

Hey Hesh, if you don't want the Black Acacia from Bob, I got lots of Australian Blackwood. Well, actually it's Tasmanian. The stuff from the little island is supposed to be the better than the stuff from the big island, and way better than the same stuff that grows in California.

Most of the local guys around Maryland list it as Aussie Blackwood. I got word from a builder in Oz that it is getting more uncommon, and that the national government might put export restrictions on it.....any truth to that? |
