Another Bore Cut?

The boring back cut . it is a very safe and controlled type of cut if done properly.

The t or the v or just the plunge and back cut leaving some hold wood and the wedging to prevent lean back.

Not quite what the drawing shows but this could be a good cut to add your skillsets.

That's an interesting notch.

That's an interesting notch.

You going to give it a try?

 

[skippysphins]

I will

 

[Ambull01]

I will

What's the benefit of it? Less chance of it rolling/falling in an unintended direction?

Oh boy.

 

[Ambull01]

Oh boy.

lol, true. I noticed quite a few bore cut threads. Anyways, I was just trying to find out the reasoning for the USFS horizontal bore cut. Didn't want to start another bore cut thread.

Learn something new everyday, thanks guys

 

[Gologit]

Oh boy.

Somebody forgot to mention the slopping back cut.

Somebody forgot to mention the slopping back cut.

along with a down from the top undercut, that shaves the bark and just gets into the sapwood.

Ambull01, there are three on this page that you should listen to without hesitation. As for advice from me, you can ignore almost everything except that and this - forget the tongue and groove trash. Not only is there no real hinge, you could put 4 or 5 trees on the ground safely in the same length of time. Ron

You going to give it a try?

ya sure, sometime.

BTW, that diagram Gologit posted is my #1 most useful databit I have gotten off this site (Thanks G!). First saw it a few years ago after I had joined, it's a great felling notch either T or triangle. That and learning about bore cutting and leaners and making use of holding wood and using hinges to steer trees.

It does look overly complicated.

I agree, that diagram is awesome. I saved it to my computer lol. That was better than the USFS documents and the BC Faller stuff.

I'd like to take credit for the CoosBay diagram but I can't. It was originally posted several years ago by GAS071, a long time member of AS. I did the same thing everybody else does...saved it and passed it along when it could be useful.
I'd used the cut for years but never knew it had a name until I saw the diagram.

Coos Bay cut is a great tool. Pretty sure I learned it here because the wildfire sawyer types I work with sure aren't that sensible.

 

[RandyMac]

heheh fiber puller

 

[madhatte]

No shame here!

For leaners this cut is a good option. I've had good luck with the V version. It seems easier to line up the cuts than the T.
HuskStihl and rwoods both give good advice but for a more detailed explanation on falling techniques check out the Forestry and Logging threads. There are people there who make their living cutting trees.

This looks the same. From the BC Faller pdf.

Noticed something else. I've been taking lots of notes lol. From the USFS pdf:

-Top bind: cut out a pie shaped section on top and release cut on bottom
-Bottom bind: cut out a pie shaped section on bottom and release cut on top
-Side bind: normally offside will be side with tension; tension is usually bowed out.

From the BC Faller pdf:




I like those. Seems a hell of a lot faster and easier than the USFS version.

Then they start doing algebra on the log:
