Stihl making a "tinking" sound

Eric Frei

Regardless of what shit you propose I stir your Junka figures failed the comparison test of oak and euc, euc being much harder for a steel ball to penetrate would likely also mean a lot harder for a steel chain to cut.

Wood has resistance upon many axis, and depending upon how it is milled also influences final strength. Just like cutting it with a saw cutting along the grain to across the grain makes a marked difference.

Our landscape here is dry sclerophyll, black wattles, eucs like ironbarks, grey gums and red gums. These timbers are very tough.

Proportionately in comparison to the USA I would say that our hard woods are more prevalent than softer species.

Shit stirring or not these are the facts, if you were to take an aerial topography of the blue mountains or hinterland here what would the predominant species be?

Eucs.

What would it be in your case? Pines? Elms? Poplars?

According to this article it appears I'm right in saying conifers (soft wood) are most predominant.

About the only rolling hills and plains of pines would be forest planted ones like I was familar with around MtGambier or Caboolture. Sometimes we get a grove of Hoop pines and again they are stronger than most pines.

Yes in this reference and thread I call wood hard or soft according to it's strength not whether it is an angiosperm or gymnosperm.

couldnt agree more, maybe i should go take some photos of canberra our whole city is considered an urban forest now with something like our goernment just announced a 20 million dollar 5 years tree project here along with the new arboretum, its not just the cutting of them as well hey ekka, mellidora etc is hell even on a 1890HD bandit as well as bloody heavy, i wont even talk about cutting dead ecs on sundays there that hard.

someone look at my link and help me understand where live oak "quercus virginiana" stands. i think the chart is pretty good i am not actually sure which one of those measurements we are comparing.
again. live oak is very heavy and hard. with good flex as well.
help. it has mpas. which one?

Quercus spp metric

pretty neat. you can click on english measurements as well.

Proportionately in comparison to the USA I would say that our hard woods are more prevalent than softer species.

That may be true in the PNW, but I doubt that is the case when you throw in the hardwood forests of the midwest and eastern US. But now we are averageing the proportion of wood species as to where they are grown? Man, you must be in politics down there. Bait and switch mentality. So you are saying that no matter how hard the woods are here, they are watered down becasue there are larger stands of softer woods nearby? Is that your point?

Here is one data point: balsa is one of the strongest woods in the world, if not ~the~ strongest by some measurements. Why? The strength to weight ratio is very high. The crappy wood that you claim that we have growing here (which we don't, but you said so in a previous post in this thread) is considered by many to be one of the strongest.

Amusing...

They don't have euc though.

Boys, Boys, Boys. We all live in different parts of the World here. What saw might, or will work in one part of the World, for cutting timber, or fire wood, or what have you. won't, or will not work in another part of the World.
No matter how much experience someone has with a chain saw. Simple as that. I've seen guys that have a lot more chain saw experience than I do, and I won't have nothing to do with them, while they are running a chain saw, and that is point blank, and period..
About 13 years ago, I was at a small engine repair shop, when these guts from Brazil came in, looking for chain saws to cut timber with. They had a sample of wood that they have down there, and it was almost polished.
I asked them, what they used to polish the wood like that. They informed me that the wood is that hard, that was from the cut of the chain saw. It was that smooth.
I asked them what makes of chain saws they were looking for. They told me that they had to have a lot of power. Now me knowing the ruggedness of McCulloch, I asked them about a Pro Mac 700.
They informed me that the Pro Mac 700, wouldn't last too long. I said that it was a pretty rugged chain saw, and they agreed, but the hardness of the timber, they just wouldn't stand up.
I asked about Stihl, and they don't last long either in the timbers that they have. I thought that, that wood must be some extremely hard stuff, if those chain saws that I mentioned, wouldn't last too long, cutting this timber.
So there you have it. What will work in one part of the World, not necessarily will work in another part of the World. Bruce.

well, were guys alright.

which euc is the hardest? species wise.
i think citrus might be overlooked.
you have a tech sheet for australia ekka?
i dont doubt eucs tuff.

Good point. Live oak is considered by many here in the states to be the strongest native wood, stronger than black locust. From:

Strength Properties of Commercially Important Woods

American Live Oak has these properties for strength:

Static bending: 1.98KK PSI
Compression parallel: 8,900 PSI
Compression perpendicular: 2,840 PSI
Parallel shear: 2,660 PSI

Strength testing defined: Hardness or static impact strength (not listed here). There are also stiffness, or static bending, also called the modulus of elasticity (the wood is stationary and bent from a fixed position), impact bending (the wood is dropped and the hight measuded when it breaks, not listed here), compression testing both parallel and perpendicular to grain (crush and fiber stress strengths), and shear strength (the twisting strength parallel to the grain).

Nope, you are switching in other regions to the one where you are and supported the Stihl shit saw range. I was specific to your location and mine however expanded to say that the eucs dominate Australian landscapes with pockets of diversity in both planted pine forests or endemic rainforests however you can expect to be cutting eucs just about anywhere.

If there are a lot of 290,310 and 390's being sold then I know people are either tight asses or cutting soft crap. Those saws die over here, simply dont cut it.

Balsa wood is a hardwood as an angiosperm but is a weak soft wood when comparitively testing against other hardwoods, any trying to change that is beyond politics but a magicans act.

Here's a comparison test of some softwoods.

Strength / elasticity of wood

Also scientists have discovered a gene in eucs that adds to their strength that they will exploit it for forest grown timber.

well this thread afterall is called stihl making a tinking sound,say no more right there, peices of crap there cheap for a reason windy plastic oil tank, plastic this plastic that, winndy whats your tertiary qualifications in arb and hort..... we should move this thread to tree facts etc.....just so noone post's there opinion and its actually fact im going to cut some wood samples and post them over to you windy.

Eric Frei

Hey, Windy is a good bloke and the most sold saw in USA is the Stihl farm boss range.

Just here it's different.

Here even the resistograph had it's troubles, wood corers have to be different to take a euc core, wood chippers get smashed and have to be upgraded for tough hardwoods, axle changes are another thing that happens a lot .... Vermeers std axles just cant cope.

This is a tough land, toughest on the planet and some of the stuff that grows on it likewise.

Coconut floor boards harder than oak and euc according to Junka tests.

Have a read of this article.

Coconut wood is new flooring option

This is why engineeers do not use Junka ratings for timber strength. anyone who has chainsawed a cocnut palm knows how piss weak they are.

If not then I shall simply enter a plea of "guilty" and with that, the defence rests it's case and pleads for leniency.

Don't take it personally. Ekka climbs with a 440. I do not know anyone else that does that. He has balls as hard (and big) as coconuts.

1127 saws can and do cut a lot of hardwoods, mine included. I personally cut up a ton of madrone with my 290 that is still running strong, and that stuff is hard as any euc when it is dry (we also have euc here). We cut over 10 cords of hardwood a year to burn for heat when I was living on the sheep ranch. Ba-ha-ha-ha!

And there seems to be all that Monterey Pine that was planted in Oz and NZ years ago... must be a hardwood variant in the species down there burning up all those 1127 saws or something. Oh, and truth be known, many hardwoods are typically not that hard when they are green. But let's keep that a secret...

We are working on a poplar gene that makes it stronger than steel, it will also be springy, so when the eco terrorists try to chop it down the axe recoils and hits them in the head.
