tree jacks

[imagineero]

So I was just having a few quiet beers and minding my own business reading up about turning 20tonne low profile bottle jacks into tree jacks for guys who can't afford silveys when I started getting hungry. Wandered off to the pantry and found some crackers, then popped the fridge open to discover that my sister in law had scarfed all the cheese. No worries because when I got back the next page had loaded and I found this;

John White Using Tree Jacks

Let 'em have it Randy Mac

or not....

He has the jacks set-up ok Shaun.

as for the saws and bars, I think it was mostly an advertisement. There was no real need for an 84" bar, a 36" to 42" would have been fine. 20 minutes spent putting in springboards would have made it easier all round. I have a feeling that there was major fiber pull defect or other fubar as the butt end had been trimmed, defeating the purpose of the Humboldt face cut. It was kind of a crap tree, lots of pitch rings.

That there was pure cheese whizz, and you're just not feeling it cause you havent got a bunch of beers into you like I did that night ;-)

Nothing wrong with the jack setup, but we're more looking at the cheese. Who even needed the jacks, the camera crew, multiple oversized saws etc. I'm not even a big wood man, but I've knocked over trees twice that size with nothing more than a few wedges and a bit of time. That there was a sell.

I need another beer. I need the holidays to end so I can have a reason to stop drinking. THen I can go to work and have a reason to start drinking again

Alright, I'm just going to take that right back there. Not twice that size. But bigger than that . Really

OK, I'll admit up front I'm way out of my league with such big tree felling, but.... the undercut pic clearly shows a bowed bar at the start of the undercut. How do you adjust for gravity when using such huge saws? I know how my crosscuts work (poorly) when bowed. Do you first center the bar, begin the cut freehand, then dog in?

Best to start your cuts with a smaller bar for a guide, then switch to the longer bar, but I agree with Randy, seems a tad excessive for this tree!

Not only did that tree have pitch rings but it also had a little fire-scar in there as well as some star shake and white speck... That's not to say that you couldn't salvage anything out of it. But to say "they don't come any nicer" is a bit of a stretch. That 84" bar did seem like it was kind of a marketing ploy for Madsens. Last I checked a 36er will suffice for a 5-6 footer.

 

[imagineero]

How about 'they don't come any nicer than this anymore'?

[RandyMac]

Oh but they do Shaun.

:msp_rolleyes: Sounds like a scaler talking.

 

[OregonSawyer]

How about as a Sawyer talking? Scalers are way too much gossip for me.

I don't know who John White is but I can tell you that boy is a stud. I don't think I could even begin to swing an 090 with a 7' bar on it. When I switch the bars on my 090 from 4' to 5' I swear the saw gains 20 lbs. I used the 090 last week to buck up a big blowdown with the 5' bar. I'm glad I had it since I could only work the uphill side but bucking with the 090 is a far cry from trying to hold it in a falling position. It takes a heck of alot of strength to fall with an 090 with even a 4' bar. Then of course there is the vibration!

The stump looks kind of funny with all that soil built up behind it. Sure made the job difficult.
