    Hello, Lee Valley customer service. My new PM-V11 chisels are having some edge retention issues when chopping dovetails... No.. Nothing out of the ordinary about the wood - I use it all the time...

    Yes - it may have a high silica content.. Why do you ask... .

    Here's a link to the chart.

    Obviously skewed to the USA market, but that's ok. I wonder how much Gidgee and Spotty they see over there? Spotty may even be growing there, but Gidgee? They've listed "external lumber" as the only use for Spotty, but we all know it has many many more uses than that (and what do they mean by that? Fencing? Cladding?).

    No mention of Oregon either.

    Yeah, I bought a 250x50mm stick of Bluegum 4 metres long from Boutique to make some pallets from, but I sanded a bit up and I think I'll make a table instead.

    Nice, FF

    But which blue gum did you buy? Sydney blue gum (E saligna) - not mentioned in the above table - has a hardness yanka of around 9 kN (Bootles), whereas Tasmanian blue gum (E globulus) has a yanka of 12 (Bootles).

    However, even with E globulus there are essentially three different "types" of blue gum on the market:
    • Old growth - Hardness 12 kN - rich dark brown timber,
    • Regrowth - Hardness 10.5 kN - slightly lighter colour,
    • Plantation - Hardness around 6.5-7 kN - much lighter colour, often similar to mountain ash.



    Cheers

    Sydney Bluegum. I have some very nice pics taken in Bluegum Forest (Blue Mountains NP) about 20 years ago, but they are trannies.

    Bootles says as follows:
    • Lignum vitae - Guaiacum officinale - Janka 20 kN
    • Gidgee - Acasia cambagei - Janka 19 kN


    Didn't realise gidgee was so soft, but it sure is prettier, especially as used by Terry Gordon.

    We here in the west consider Wandoo a hard timber with a Janks of 15.0 according to this http://www.artistictimberfloors.com....ss-Ratings.pdf it shows Bamboo as 14.7 Janka .
    I have some Wandoo growing here ,a good chain is required to get through it .

    Hey Fence,
    'Oregon', as a species, is short for Oregon Pine. Found this very good info at Wooden Boat forum.
    Oregon Pine is Euro (and Brit and Aus) speak for Douglas Fir, Pseudotsuga menziesii.
    Prior to its getting parked under its own genus, Pseudotsuga (literally, "false hemlock") back in 1867, it was at various times parked under all of the following genera: Pinus (pines), Picea (spruces), Abies (true firs), Tsuga (true hemlocks), and Sequoia (redwoods).
    When I moved here from California in '87 and went to work for Hudson's in Blacktown, I was heartily confused over the Oregon thing, cause I KNEW that most of their 'Oregon' was actually Canadian! Douglas Fir is indeed on that list. Not really very hard at all and with a very unforgiving tendency to splinter. Requires a bit of experience to use in fine woodworking. Old growth, rarely seen, save for recycled, is preferred as most stuff you would get at a timber yard is unseasoned regrowth and very 'bony' in reference to the marked difference in density between early and late wood. Think 20 rings per inch or more for old growth. HEAPS more stable and softer to work. Here's a link to the WIKI page, which is VERY informative.
    https://en.wikipedia.org/wiki/Douglas_fir
    Hope that helps. Cheers

    G'day Jim, yeah I know - I was just being cheeky to see if I could get any bites - so thanks!

    Actually I didn't know about it being called Oregon Pine (and it's a Fir) but the legend is that some genious called it Oregon because that was what was stamped on it when it arrived here. I've always been amused by the thought of some Aussie going to a lumber yard in the States to purchase some Oregon. "Well hey buddy, just how much money have you got? You want a coupla acres or just a house plot? Not a real friendly climate up there though....."
