The fact that you can see the medullary rays rules out the acacias. I'd go for one of the tulip oaks (eg Argyrodendron spp). The bark looks right also.

Hard to be definitive from the photo given but it looks very much like Commersonia bartramia or Brown Kurrajong.

Regards, Timboz:roll:

I agree with Wood Collector. It looks very much like a Swamp Mahogany (Eucalyptus robusta). Koalas love them.

Toymaker is correct. Seal all around each board and bond to plywood with an elastomeric compound (eg sikkaflex) and you won't need screws. By sealing (particularly if you use epoxy resin) you are...

Your timber looks like it is treated - core yellow brown (no preservative uptake), sapwood greenish grey (CCA taken up). However the greenish grey may just be fungal (blue) stain. Inhaling arsenic is...

Resin tends to deposit around knots in pine - hence the stronger smell. The fact that you can smell the scent tells you it is volitilising (evaporating) and therefore it diminishes with time....

Your wood is likely to be CCA treated given its probable age. Testing is based on detecting the arsenic component which behaves chemically like phosphates and is complicated by the presence of...

Walkertone, did you read my previous post titled PINE? Your wood is absolutely, positively, iron clad, bet your house on it, PINE. Only pines show needle trace. Your smells recently posted are pine...

Hi Walkertone,

Your wood is definitely a pine. The reason is clear in your first image. The board at the bottom of the page shows needle trace (the regular fine dark spots down the core of the...

Was spill the beans a pun? I'll go for Brisbane Wattle (Acacia fimbriata):?

Timboz

Dengy,

I'm guessing that the cracks run through the pith (centre) of the log. Cracking like this is commonly associated with the timber in and around the pith due to chemically degraded timber in...

G'day. I'm pretty confident that it is Tasmanian Blackwood (though not necessarily from Tassie). The stain-like dark patch on the top board of the last photo is often present in this species. If I am...

Silver Ash will start out almost pure white but will oxidise to a pale golden yellow (about half the intensity of the smiley icon below) under clear finishes.

G'day Tony,

I had always wondered why G.M was called Dead Finish until recently when I found a reference suggesting that it is short for Dead Smooth Finish as a reference to the way it planes up....

Hi Sigidi. I agree that it is unlikely to happen when cutting deep plunge cuts but it is a handy problem to have a heads up on if you are a newbie. It had me scratching my head for a while the first...

Hi Phil. I agree with all the comments so far - some wise heads helping you out. One other possibility is something that has happened to me a few times when I haven't been paying enough attention. If...

I haven't milled any aulocarpa but I've been eying off a big fella that has fallen over on my block. I'll have to sniff him out when I get around to milling him. Incidentally I always think that...

Sorry Mapleman but I think you'll find that Onionwood (that was substituted for Toona ciliata) is Owenia cepiodora and Miva Mahogany is Dysoxylum rufum (mollissimum). Onionwood is extremely rare...

Timboz - i will do. I'll try and pop into a cabinet maker in the local area or up in the blue mountains when i head up there next. That flat steel bow is interesting, do you by chance have any pic's?...

Boris,

Please take note of what others have contributed about the behaviour of 'turps' - they're right. Turps is a difficult timber to process (warping,high silica content), particularly at that...

I should have smoked (I love nautical language) this earlier. Pretty hard to miss those big seeds eh John! By the way, do you have Bill and Wendy Coopers "Fruits of the Rainforest" book? It is a...

My original guess was rose butternut John. I have access to a fair bit of cabinet timber so lets send a little money to the Salvo's and put a hot meal in someones belly.

Fun game, Timboz:)

Interesting that you brought this up. I'm a fan of the show 'Grand Designs' where green oak is often used - splits/checks like crazy and the Poms' seem to love it.



John' I've not heard of...

Never seen this timber but based on others thinking Coachwood I'm guessing Satin Sycamore, Ceratopetalum succirubrum (relative of coachwood)?

Timboz:?

Spotted gum produces a very wide variety of colours and grain patterns. Your pic may be spotted gum but it usually does not have as much red as that. Be aware that the amount of 'green' will vary...

Try searching "Sawn timber from native forests and plantations in Tasmania" and you should get the paper.

Happy hunting, Timboz:)

Here is another link that you might find interesting Mapleman, and more particularly "an oxidised pointed iron rod" who is older than us and (probably) has fewer fingers than us who is also trolling...

Unfortunately that paper didn't include any photos. Many of the scantlings produced from young eucs tend to look like your standard knotty pine studs depending on the pruning schedule or self pruning...

I agree, it comes back to your earlier comment about high end versus low end product :- serviceable if young and dry - yes, premium product with maximum strength and service life - no.

Regards,...

Hi Wattsy,

If it is red ironbark it will be extremely dense 1120kg/m^3 (c.f crappy pine 540kg/m^3). If it is not that dense it may be Mackay cedar, which I think was widely used for patios and...

Rustynail,

It is true that heart will undergo accelerated decay but the decay is predicated upon chemical degradation having taken place in the living (or whole dead) tree which renders that core...

[QUOTE=Sigidi;1759774]Absolutely nothing wrong with boxed heart timber!!!some of the best posts you can buy will be boxed heart - but as always it is down to the miller to select the log for the...

Weissyboy, it is true that you can 'sell' the virtues of untreated class 1 hardwoods if you are speaking directly to the end user. I think the point of what John and I are saying is that most timber...

Mapleman,

I'm guessing that is only fencing grade? Would any mill sell structural hardwood for $500 a cube? They'd be broke quicker than a drunken sailor in a casino!

Timboz:?

At 12 years old this E. grandis material is exactly the sort of material that I believe is more usable than has previously supposed. At that age the core wood simply hasn't had time to chemically...

John, I share your frustration regarding overtreating timber. The 'it's treated it must be better' mentality is alive and well. I'm constantly scratching my head when I see beautiful sapwood free H3...

A beautifully written response John, illuminating the competing pressures and rationals behind the changing standards. I fully concur with your thoughts about machine proof testing as the answer....

AS 2082 allows heart in, for sections 175x175 and up, but it may be that a clause change now allows heart in for 150x150 and up in certain situations. It's not a product that I would recommend, nor...

Firstly, I second John's comments. If you want to go untreated you don't have as many local options that are durability class one in Melbourne as we have up north. Having said that, you shouldn't...

Lappy,

I agree that it is not red cedar as red cedar is ring porous and that does not look to be. The boards look fairly wide (+250?) and are quarter sawn, so from a fairly large tree and stable...

G'day Lenz,

Try researching the genus 'Brachychiton' as they (mostly) have maple shaped leaves and are native to rainforest (wet and dry). Again, without a photo it is a bit of a lottery.

:)...

How true to life is the screen rendition of colour Mapleman? It certainly is an intense red on screen - you'd swear it was a rosewood of some sort alright.

:) Regards, timboz

Sent two P.M's, Timboz

A case of "Rome wasn't built in a day" ? There are some early benefits from thinnings as firewood - the women in developing countries spend many hours collecting firewood. It certainly isn't going to...

I absolutely agree with you Rustynail. I'm not sure why this is going south - we all know how spring affects logs and scantling as it comes of the saw but it seems to have evolved into some sort of...

Did you read the post about geometry? I acknowledged that a longer (and commensurately heavier) log will bow up more and went on to explain why. We know the same things - a skimmed log bows up...

You are correct Sigidi. A longer log with more weight will deflect up more but not because the log weight is not having an effect - it has to. Any beam sags because of it's weight. The answer lies in...

Very true Rob, exactly the sort of thing required to get these people out of poverty and everyone and everything a sound future.:U Timboz.

Mine too,

Best all round timber in the world I reckon. I've heard the mills in NSW are paying $200 a cube at stump (and not for big trees either). Thanks for the info.
