    Default Acacia microsperma - Bowyakka

    In looking into the wood from Acacia microsperma, I have seen the density listed as 1320 kg/m^3, 1100 kg/m^3, or the same as Acacia cambagei (Gidgee: 1250-1350kg/m^3). Does anyone know which value is correct? More importantly, who actually has some of this wood to sell? "Ringed" Bowyakka seems to be the grand prize.

    Here are some links related to this wood:

    I've also included maps of where the tree is found. One is from the GBIF database and the other is directly from the ANBG.

    Runge find a town called Quilpie, which would be smack in the middle of that large black blob on yr bowwyakka map and call up the local pub on friday evening and ask if anyone knows anything about it...or contact some of the local woodworking groups....around south western qld or lightning ridge or St george or bill harms at carbarlah....someone will be have a collection of it..

    i scored a piece of bonewood from that area one time..awesome stuff...

    sounds like its time u bit the bullet, flew to queensland and hired a 4wd and chainsaw and went for a drive mate...!

    Bow yakka. Heard of but not seen No doubt as tough as buggery.

    Yakka is an aboriginal word for work.

    BTW, what's the attraction to all these dense timbers. Must admit it is interesting stuphpph.

    Thanks reeves! I was hoping that an airplane was not required. San Francisco to Brisbane tickets aren't cheap! By the way, don't you irritate people by running around whacking their trees without permission? I thought about doing that along the western coast of Mexico where Libidibia sclerocarpa grows. I was strongly warned that this was a good way to meet angry people and lose my car.

    So, what is Bonewood? Bosistoa selwynii? Macropteranthes leichhardtii?

    Thanks artme! To me, I am looking for something that is exceptional. The densest woods in the world are marvels of nature. Most mechanical properties of wood are directly related to density. My idea is create a spectrum of wood colors and figurings that can be used to make wooden items. The caveat is that the woods must be the densest woods in the world.

    Here's the cutting board that I am having made (computer rendering). The woods are:

    Sides: Libidibia sclerocarpa, Guaiacum officinale, and Bulnesia arborea
    Perimeter: Zollernia paraensis
    Corners: Schinopsis quebracho-colorado, Caesalpinia platyloba
    Star Perimeter: Swartzia panacoco
    Star: Brosimum guianense, Acacia peuce, Acacia cambagei, Schinopsis brasiliensis, Krugiodendron ferreum
    Center: Libidibia paraguariensis

    Thanks! I hope that when it is finally assembled, it doesn't explode.

    So, have you stumbled on any interesting woods while in Brazil? Take a look at this website: Banco de Dados de Madeiras Brasileiras

    If you should happen to stumble on anyone who sells woods like these, please let me know. I can't find any good wood stores in Brazil that have the really exotic woods.

    I've used a little of it and it is hard as nails being a desert acacia. It is related to gidgee and often difficult to notice the difference. It is very difficult to work with using hand tools but turns relatively well with sharp tools and polishes up extremely well.

    Cheers, Evan

    Macropteranthes leichhardtii? it is...bit like gidgee but blondey golden color...very hard witha deep polished sheen

    and yes its good to get permission from landowners before lopping trees on their property, a carton beer would do it in most cases..'but' a cursory drive through those areas will lead you to many places where there are no land borders, no identifiable ownership, side of road stuff and plenty of 'owners' who have no problem with someone cutting up dead logs..which last many years in a lot of cases..along riverbanks and dry creek beds are a good place to look and you will find roads and places where you might wait days or weeks to see anyone..few people would care if someone loppoed a few desert trees..there are huge land areas with no people or fences...huge mate...have fun...

    Lazarides is alo probably a better bet than moxons they often have diverse destert wood sin there..

    Hi reeves,

    Thanks! I've never dealt with Lazarides but I did buy some Acacia xiphophylla from Djarilmari. As far as Sustainable Desert Timbers, I put in a request for any wood that they might have which had an air-dry density > 1250kg/m^3. Haven't heard anything yet.

    Someday, I'll fly over to Australia and whack some trees ...

    Evan - thanks for the info.

    Hi Folks,

    Here's an interesting document that mentions Acacia microsperma. Any ideas
    on where a person might find some of this wood to purchase?

    http://www.santos.com/library/Santos...ield_Guide.pdf

    For that matter, how about

    - Casuarina pauper
    - Acacia rhodoxylon
    - Lysiphyllum carronii
