coos bay for large heavy leaners

[Burnham]

I agree with Willie...not likely you'll close it up, but keeping it from flying around is a good plan.

Good Luck!!!!

just as a sidenote.............the diagram gary showed, shows the triangle with the apex towards the lean. If you guys might recall, in Dent's first book, he shows a diagram with side notching and the apex is towards the rear. either way, the idea is to get rid of the tension on the sides of the trunk so you don't rip straps from the roots, etc.?

 

[pantheraba]

Good catch, Sierra. I'd like to hear if it makes a difference on where the apex of the triangle is.

 

[SouthSoundTree]

I was thinking that, too.

I think that the triangle is used with a notch, so it would have to have the narrow side of the triangle as the hinge.

If you were to try a triangle, apex to the lean, combined with a Coos Bay. I think it would pinch.

With the golden triangle method, the apex or point of the triangle will indicate the direction of fall.

Thought I'd left some pics of it around here somewhere. Not convinced it would work with that strap though.

The options presented by the triangle strip approach are interesting. I've never done a Coos Bay that the strip wasn't set up as even, front to back...whether it was the Burnham method with a face and hinge, leaving a T shape to back cut, or the Davis/Beranek method with no face cut at all.

I've done the pair of angled faces that Ed brought up...in that case the leave strip had the apex to the rear.

tried a couple of cb's this week on some small trees......12"ers.........you have to cut fast and not slow down in the middle, otherwise they will barber...........

 

[Burnham]

I think I told you that...

 

[sotc]

Sounds vaguely familiar

If there is any side favor you got to cut that side first and stick a wedge in it.

 

[sierratree]

yep.............that'l be the off side. and once that's done i don't plan on going back around.............will stick to my escape side.............

 

[sierratree]

well, are you saying cut the offside first (side with the favor), or throw in an undercut first, then the offside. btw.....no coos bay on this one. just the standard shallow undercut, trim the sides........trip with boring backcut.

 

[gf beranek]

With the stump condition you have it throws a proverbial wrench into the works. As far as the coos bay goes. However you do it now is all situation dependent. I still think cutting that back strap is the key to getting the tree down as easily and safely as possible. If the tree doesn't go then you don't have that to think about anymore.

I'll see if I can dig up some pics of trees in similar scenarios.

 

[gf beranek]

Here is a small assortment of pics showing some trees that were being held from falling simply by a holding back strap. The trees that were cut posed some risk to passers by and the highway. The one that broke by itself left the strap standing in the air. Although it could have been cut too, but probably let go in the night during a storm.

Actually over the years I've seem many examples of this very thing. Problem trees for sure. Conventional falling methods and wisdoms do not apply with these. Be careful whatever you decide to do.

 

[sierratree]

Those are great photos.........Did you fell some of these? or just happened by them for a kodak moment? If we go for the strap first, still will bind it up real good with wide webbing and tensioners. So is this Gary posting this thread?

 

[Burnham]

You've been getting advice and input from Jerry Beranek...the Jerry Beranek .

It doesn't get much better than that.

 

[sierratree]

Thanks...............hope to meet both of you in the future..............which would be great...........

 

[woodworkingboy]

Nice way to gain confidence by looking at GB's photos and seeing the rather large trees that folks in the past dealt with, presumably successfully.

 

[gf beranek]

It's a dicey situation anyway you go about it with trees like that. And yes those pics are snap-shots I took during my hikes in the parks. But I've seen many same examples in the second growth.

 

[sierratree]

We're off to take care of this tree, tomorrow.........Didn't realize I was interacting with some of the best and knowledgeable sawyers around.........So.............Thanks..........Will get back with some video and pics........

 

[MasterBlaster]

That would be nice and yes! We have a pretty good crew here at the TreeHouse.

 

[flushcut]

Be safe!

 

[woodworkingboy]

Looking forward to pics.
