Hardest wood on earth

[VinceGU05]

using 3/8 or .404?

3/8

When cutting old dry wood like that, I find myself needing to touch up the chain every tank off fuel.

Id rather be sawing it than splitting it.

great video!

Another one dry Yellowbox brand new semi chisel chain didnt last long on a strong ported 461 check out the dust and watch for old mate in the back ground going ass up.

After watching the cut speed of all the ported saws in the states, a bloke in Oz can be lead to believe that a ported saw will run MUCH faster.
@stihlman441 , your first video really shows the difference between our timber and northern hardwoods like oak.

In your opinion, what is the cut speed in our timber between a stock and ported 70 - 90cc saw?

Is it worth messing with?

I have wondered why porting seems to be so popular in the USA, but has never taken off here to a similar extent.

Im a big fan of ported saws have been for years and wont do with out them.
In the US they like there saws to have high RPM for there soft woods here in Ozz you need torque to get the job done.
For me a ported saw is like using the next size up saw but without the extra weight and that makes a bid differance when hanging onto one all day.

 

[Brewz]

yep, that really rings true!

I have with held copying what is done in the US because I just cant see a saw running that fast in the wood we deal with here. Their saws just cut to fast to be true.
I want to increase my saws performance to make the job easier, but dont want to fall into the trap of faster is better.

I guess nice open exhaust and free flowing filter are key but now to re-assess all I have read to learn porting for torque over RPM.

I wondered why the ladies call me the great buloke...

Its the drop bears you have to watch out for

 

[Iron.and.bark]

All I do with porting is.

Squish reduction, widen intake, widen exhaust, muff mod. Don't touch the transfers.

Looks like Brads in some trouble there

Is that yogi bear about to do something "uncomfortable to talk about"?

Just to show what the OP was saying.

5060 Buloke Australian {Allocasuarina luehmannii}

Compared to one I cut alot of.

1210 Oak Black {Quercus velutina} - Red Oak Family

Page 2 of this thread I have them all listed. http://chainsawrepair.createaforum.com/trees-flowers-plants-etc/tree-lumber-hardness-rankings/10/

The hardest wood I ever cut would be acacia, 7 years seasoned without a single piece of bark on it.

Acacia is supposed to be 1750 Janka.

It pales to the 5060 of Buloke.

You guys might be better of cutting Your wood with demolition/cutoff saws and diamond blades.

 

[jmssaws]

My wood is still harder.lol I got a bunch of that stuff. some pieces would weigh 300 pounds. I have a log that's about four feet long and couldn't tell you what it weighs, all this stuff is under a lava flow

My wood is so hard that a cat couldn't scratch it.

 

[jmssaws]

This is a post oak fence row tree and about as hard as it gets around me.
Deeter is running the 064 that @drf255 has now with new rs 404.

 

[jmssaws]

Here's his mildly modded 090 in the same wood

The saw is a beast and gives me pretty hard wood.

You saying that gives me hard wood also!

I laid down a big hedgeapple/osage orange a few years back, figured that I would finish cutting it up in the winter, when
all of the brush had died off. It was like trying to cut concrete.

I had to sharpen the chain after one cut, it is still there....

There is so much good firewood in Oz that I give away the lighter stuff I have to clear away to get at the good stuff. However, the hard stuff is rough on chains, I change chains every tank of fuel on a lot wood. Then there was this log, maybe Acacia (I don't know) that the chain would get a grip, but the wood fibers were so tough the saw would bog down very easy. I couldn't split those rounds and gave away some of the rounds as a joke to my friends. They're probably still trying to split them.

I've also had 170gn 30-30 rounds bounce off of Ironbark without even disturbing the bark, just a smudge of lead to show where the rounds had hit.
