Anyone felled in NZ?

[davidwyby]

I joined a NZ felling group on FB and it seems they have some different felling cuts. Still trying to figure them out.

What's different?

Coriolis effect?

 

[CurSedVoyce]

Well, that would be a different spin on it.

 

[gf beranek]

What are these different methods anyway?

Curious minds want to know.

The most confusing one was one that was leaned into another tree and he knocked it out with a push tree. I couldn’t see the whole setup of things, but it didn’t look like it would work…but it did.

These seem a lot like the Murphy's "out of the box" techniques.

Better stump pic

They seem awful big on training and safety.

What does that stump do for you? I think I get the general scheme, but the lower backcut I'm unfamiliar with.

 

[stikine]

The first bucking picture you posted would get a faller fired here.

 

[davidwyby]

The stepped bucking cut was cutting a log from an uprooted root ball or rather plate. Stump to the right.

Reminds me of a “kickstand” you are supposed to leave on a pushed tree while you’re felling the push tree. Basically it’s holding until it’s overloaded and the grain separates vertically.

 

[stikine]

There are other ways to do that with out wasting fiber. Of course it depends on the end product...ie. Pulp vs sawlog.

Exploring more…I think the low back cut is supposed to make the tree fall slower.

 

[davidwyby]

Not unusual here. Bit of lean to the far side, a Dutchman there, but no sizzy on the close side…but I don’t think it had enough lean to warrant a sizzy. I think I would have just done a tapered hinge.

 

[davidwyby]

This is the one that weirds me out. Screenshots from a vid.

Hard lean away from the camera “80%”. Felled from right to left with a push tree.

It worked.

 

[davidwyby]

Left is face, called scarf I think. Back corner I think is a “box cut”?

 

[davidwyby]

 

[friedrich]

some people use the lower backcut when they use a strong but low pull so they don‘t rip the tree off the stump.

 

[davidwyby]

The mohawk down the middle of the back cut is the release cut, bored in from the back.

 

[stikine]

I gotta ask why? Open grown tree...does it need a special cut? Maybe just for show or video?

Video doesn't play for me, fwiw.

Looks like how trees are felled in the UK , Europe and OZ. Nothing revolutionary.

plenty of boar release cuts with a lot of fibre pull from head leaners and not always the tidiest saw work. All works well enough when putting timber on the floor
