Tree properties when stressed/being cut

[kmac]

Hey all,

Need your help once again - I've tried looking everywhere for an answer for this but have had no luck. Seeing as I've only just begun, hardly cross cut and not felled a tree yet, I'm calling upon your fantastic knowledge/experience.

 

I'm being asked to "describe the different properties in relation to the way the timber behaves when stressed/being cut".

 

Could you help me out on Sycamore, Larch, Lime, Ash and Western Red Cedar

 

Always grateful

Sycamore very brittle tends to snap off the hinge too easily, so no good when you need the tree to remain attached or to get it to swing/ or move against direction of fell.

Ash flexible fibers, so good holding capabilities, but can badgers chair very easily. Extra care needed on leaners.

Larch, the itchy tree, i will leave you to find out why.

Duglas fir is suseptible to but rot on damp sites, so you need to check the wood in the mouth before starting the back cut, and alter accordingly.

I think you mean 'barber-chair'

Nope i mean a badgers chair, how often do you see a barber in the woods.

More than you see a Badger sat on a chair!

We need a German arborist to contribute.

 

They have divided their trees into polite ones and rude ones.

 

The polite ones, when they loose branches do so slowly i.e. Ash

 

The rude ones, just drop branches without warning i.e. Horse Chestnut

Had my first Badgers Chair today.... it was an ash.

I don't think the strong wind helped much, or the fact that my bar didn't reach all the way through on the opposite side of the hinge.

Kind of crapped myself at how fast it happened!.... and we were on a slope.

 

I did a standard felling cut and can now see why a dogs tooth cut is so useful.

Lost my nerve on tackling the other ash trees on site so left them to someone else.... but all the larch I cut went down fine, despite the wind.

 

Change of underwear.

cheers, steve

Whoops!

 

We've got a helluva wind, so no woodland epics for me today thanks. Ah! the luxury of not having a client.
