the all aussie dribble thread!

I've also seen Candlebarks (E,rubida) droping limbs in the same circumstances as i mentioned.

It's bizzare the way these Redgums drop limbs. They don't swing down as you'd expect but just "blow off" and hit the deck horizontally.
It's like they've had a few kg of TNT strapped to them.
It made our local paper but a heap of girls on an end of season Netball trip were lucky recently. A massive Redgum limb dropped on their houseboat while they were all sitting on the back deck. If anyone would have been in the front they'd have been seriously hurt, if not killed.
Some people have said they were probably trying to reverse out while still tied to the tree but I digress...

it's a pity you aren't a bit closer matt i would like you to run me 460 now that thing has balls just as quick as a ported 660 that randy done

but i'm about to put a base gasket in it to lower the comp .

From memory the only 460 I've run was Andrew's stocky and that had some pretty impressive torque. Stock 7900's are similar if tuned properly. I remember when I'd been falling for ages with my ported 7900 then went back to my stocky. I was actually pleasantly surprised with the torque it had considering I'd been blinded by ported saws It was also a lot quieter which was just lovely.

If you lean on your 460 or get more aggressive with the chain do you think it will hang with the 660? If they were both built to the same type of specs you'll find the 660 will walk away from it - straight to the nearest fuel station anyway!

Hey its a funny one mate but it's so hard to compare saws that it's not funny. I've had a certain builder say that I needed to run one of his 660's to know what real grunt is like after I mentioned that the 660 Brad built for me was a beast. He hadn't even run Brad's saw but assumed his would be faster. That sort of thing goes on all the time on AS from builders and it ***** me - guys like Cahoon, Timberwolf, and Copsey would be sitting back laughing their heads off
Now I know Brad isn't the best builder that's been on AS but it seems like those who start the most build threads must be the best builders I'm happy with the saws Brad has built for me though as they are all still running and they've more than paid for themselves. I know other well known builders whose saws have gone down with less than a few hundred hours on them. Normally due to poor port bevelling leading to premature and unusual ring wear/breakage. Some of Brad's saws I've seen have also had issues too so I'm not playing favourites by any means. Uneven port bevelling is a sign that the so called "expert" builder isn't as good as he thinks he is.

I don't rag on any builders but I can't stand some of the more recent threads where builders play a game of "My dick's bigger than yours". Going back a while there was a GTG where builders ported 372 Huskys or something like that. From memory a Copsey saw came 2nd or 3rd and all the noobs assumed that the guy who won must have been a better builder than Copsey because his saw beat a Copsey saw in a 12" softwood cant!!!

Sorry for sounding like a miserable bastard but I remember when the 1st page of the chainsaw section was that full of a single builder's threads he must have been porting 30 hours a day. Thats what I was getting at above when I said that most newer builders are simply not putting the same amount of time into saw development as the older builders were yet they give the impression they are turning out the best saws the world has ever seen - it's more marketing than actual science.

We have a few Blakelys red gum left around here, in my life time i've not seen this variant shed limbs like those close to water.

 

[Rudolf73]

Yep !

Well isn't that something! How are ya Phil?


I'm back down south in the cooler climate, time to get into some firewood now I think.

Oh and for the record, Belarusian women are better than their tractors... which are built in the city of Minsk, which also interestingly enough where the great women live. So in other words they are like chalk and cheese. But the moral of the story is Belarus tractors have an engine driven air compressor which is rather neat I must admit.

Yep. The higher the access to water the more vigour. The more vigour the more sap. The more sap the more expansion. The higher the expansion the higher the propensity to drop limbs. If you look at all of the larger River Redgums in our area you will rarely find a single tree that hasn't shed a big branch at some stage.

I'm good thanks !..........I had a women once that had a built in compressor !...........always had me under the pump!!

My mate has one like that, well so he tells me, he found her in the former USSR, lovely girl, goes by the name of Slobberdownmecockyab1tch.

What no pictures of busted bunnies where are you 460 ?

 

[ausneil 1]

You got me convinced bro, I'm going to order a MS 441 R C-M soon as my wife allows me to.

How busy is your guy that ports saws? I am sure keen to give him some work if he has the time.

Reading your ramblings in the other thread a ported 441 will do everything I will need it to do, and when I get onto the larger stuff I stihl have the MS880 and the MS660's

Interesting reading, one trend I have noticed on this forum and other chainsaw forums is most of the members want or need their new saw ported immediately. In other words its being excepted that porting cylinders is mandatory so the operator can go and do some work.
I have spent my adult life on saws working with them every work day, I have never used a ported saw in professional log falling yet, I have never used a toy (small saw) either.
I'm not about to run anyone down for having a saw ported for extra performance, the point I'm making is whats wrong with a factory 660 or 395, these 2 saws are the mainstay for professional log falling in native hardwood forests.
The 084 then 088 were the top stihl performers for years in native forests and equaly the 3120, these big saws have made contractors and fallers a lot of money over the years as did the 2100,076 or mighty 090 and even big macs played a massive roll in timber production. I even knew work mates who used dolmar (mainly the 166, later the rebadged mac version) in spar sized log stands.

On a different note,
we have had 441 saws given as prizes at some larger saw racing shows, they look good and would be a nice little saw, so far none are racing competitively in their class. Now the 460, that's a different animal and every Stihl competitor has 2 or 3 on their utes done up at different levels and are extremely popular in racing.

Although that cuts the mustard in a pinch and is better than stock if you talk to any builder they really need the whole saw to do a decent job. Many builders won't even think of doing the cylinder alone and actually refuse to do it like that.

Sorry, but I have to argue that that is simply not the case. Most all of the saw builders here in the western US do exactly as I described. They send the jugs out and do the rest themselves. I can list many top 'builders' here in the west that send their jugs off to get cut. Its the standard process here now. Also guys like Randy can pretty much cut a jug any way that you want, with whatever squish you want and whatever timing you want. I do not know any builders worth a shyte that need a full saw to do a build any more. I have done several pop-up mods myself. Those saws screamed. Pop-ups are not that hard to do. They are old school now though. Cut squish is harder and take more tooling, but they can be done for cheap by someone else. If you have half a mechanical brain and tools, you can do mods as I have described and get a fork of a lot more than wimpy mild gains. You can have a screamer. If I have done it, anyone can.

Most want factory reliability and warranty just in case yes Neil very few need a hopped up saw in the bush to use everyday ..... trouble is this site is a money maker for those who wish to profit from something not really needed.

There great with a turbo hanging off them. That saw seemed lacking tho was like a strangled fart

There is doing a build and then there is doing a build. I'm not saying you can't get good results just getting the jug and slug done but there are also things such as case matching. A lot of builders don't even know it exists. Carby modifications are another thing. I've run a number of ported saws from a number of builders and let's just say the difference between builders is significant.
A build once cost in excess of USD$400. Then 200 builders appeared overnight and that price got halved (or less). If you have to cut prices to get business then it's fair to say that build quality will suffer to some extent.
I have no dramas with someone getting the cylinder machined and then doing the rest themselves but if any builder thinks the customer will get the best ported saw on earth when all they've seen is the piston and cylinder then they're kidding themselves.
By the way I'm not claiming to own any saws that have been built to the full extent but I've run a few that have and the difference in performance is significant.
I'm not trying to start an argument but do you think modern builders on AS are spending the same time and doing the same development on saws as guys like Cahoon, Copsey, and Timberwolf? The frequency of build posts would suggest not. From what I've seen a proper carby mod would take just as long as the cylinder porting.

They may even use more fuel than a stock 660.

I actually agree to some extent but in my case and falling windrow trees one after the other at 2-3m spacings my ported 7900 put 20% more trees on the ground in the same time as my stock 7900. There are a lot of variables though and a lot more marketing than fact. Mine is a unique situation and now I'm into smaller trees I doubt a modified saw will be any improvement over a stock one.
I've seen a whole heap of young members recently running around AS chasing their favorite builders like 13 year old girls at a Justin Bieber concert. It's actually pretty funny
They even request stickers, get their saws signed, and ask for T Shirts like their favorite builder is a Hollywood movie star. Fact is that nobody outside of AS has ever heard of them.

IME yes, or maybe even longer, it's fiddly arse stuff (but well worth the effort) and I'm not an expert in any way, shape or form.

From my days of 2-stroke motorcycle racing, carb porting is as simple as changing out jets in my experience. You can swap carbs for ones with larger bores but that requires a supply of carbs, and is not needed in my opinion. The objective is to get more fuel into the saw. Once you have the formula down it is not an art any more though, but a mass production process. Which is what most builds have become these days. With x-torq/strato saws, muffler mods are not as important and do not result in the same gains that pre-EPA saws had with MMs. And with Autotune/Mtronic saws, they adjust ignition timing and carb tuning, so muffler, ignition and carb mods have become somewhat obsolete. The key these days in porting saws is increasing compression by grinding the jug base to lower squish, and then either turn a pop-up piston or a cut the squish band. In effect, they are making them higher displacement saws. Which is also having the undesirable effect of shortening the life of the saws from added stress. Beyond that? You can mess with all kinds of other stuff, but the results are generally less effective.
