Let’s see some stumps

I don’t know squat about eucalyptus, but could you put a taller gap in your face? I’m guessing you hinge tears too early. Your face cut looks close to the heart, might get more stringy fibers closer to the sapwood. Not sure if having a knot in your hinge helps either.

Can’t say it looks bad though, just brittle.

What I got wrong was I missed the knot. Left a little dutchy on that side too which probably failed the hinge too soon.


But the main thing is I cut until the tree tipped and so the hinge was too thin and snapped off at the top off the face. It should separate and peel/fold down and away.

Like this:

Really it was fine, the tree went the right way. Just could have been better. Need to leave the hinge thicker and use this:

And what is that? Not a pointy piece of scrap metal like ketchup suggested earlier?

Ok, read/rate my stump, what all did I get wrong?View attachment 376470View attachment 376471View attachment 376472View attachment 376473

You used a chain saw and not a concrete saw?

Methinks the resourceful desert beaver is attempting to utilize a commonplace item from his natural habitat as a directional persuader of sorts for
detractisque corticibus. Or, in English, David's gonna use that as a felling wedge.

Ok. But I’m not getting it,, what’s he going to do? Jump up and down on the end of it? Desert beavers are odd

Few can fathom David's mind, but I'm thinking he might be looking for a wedge of massive proportions similar to the old redwood ones that are still floating around. Or he wants to use it crossways instead of poking straight into the cut.

 

[davidwyby]

Thought about cuttin it in half. Pound half in, then the other half next to it. It’s 24” long and 1.5” on the big end. Tree forcer.

Then there’s this:

But ain’t gonna try that on a Euc.

And I should say, ( back to my thin hinged stump) that it was ok cuz it was just a spar and going mostly with the lean… if it had side lean, no good.

That’s some righteous talking right there , Lol

Yes

It looks like you bypass cut the top of the face, and got compression build up that broke the hinge.
you also have you back cut high for that cut , if you look at the tree as a peice of celery, where you severed the fibers in the back cut it shortened the hinge face or rather the working fiber, which is always pronounced in a very hard or dead wood because the fibers dont flex that well.
Things you can get away with in a green pine dont always translate to hardwood.

This is your line of compression that broke the hinge.

I feel like spars don’t hold as well as trees with canopy.

The left is what I was going for. Probably would have gotten it if I had stopped sooner on the back cut and wedged it.

Less weight…but dead spars, yeah more brittle. I have has better luck getting these Euc spars (live) to go where I want than whole trees.

Rest of the story:

I blame @Stump Shot for the over cut…his porting makes the saw too fast. (2188 36” round skip)

Noted; Port any future saws for @davidwyby slower.

Have you tried a vertical bore cut here?

That is the plan. I haven’t yet due to tight shots and not wanting to miss my gun stabbing a 36” bar in the tree.

Another note is that with a full tree, the hinge needs to be thick enough to support the weight of the tree. In my back yard Euc vid (which I think has been my best hinge yet) you can see the hinge being compressed at the bottom by the weight of the tree. Less weight (spars) thinner probably Ok.

I need to get the 288 @Crocky28 ported the cyl for me back together and compare them

It was terrible windy too! Which is something that can change dynamics of a hinge.
Honestly any gust over 10mph and I don't cut trees ,unless its an absolute emergency.
