Rate My Hinge.

[MattyF]

Have found with coming in with the back cut lower that it holds for a lot longer??? maybe better with sycomore?

[Rich Rule]

the trees were pulled over by a winch connected to a ms440 with 1 ton of pull at max revs. anchored to a tree in line with the fell. tension is applied before you do the gob therefore you are not removing the tension from the leaner as such.

 

stevie, the gob is what I would describe as a big gob, just under half the way through giving a wide hinge and putting the CoG in favour. Back cut done an inch or 3 below face and once the hinge is set the fibres break like a step and create a ledge. winch away.!!!

 

I agree the highest anchor point for the pull line and the longer the better but the tops of these trees would have snapped out if we had attached the winch higher.

 

All nine went where planned with no problem.

 

Nige, it is not really my cut. at first I thought it seemed strange and I have been grafting with the guy quite a bit since last Nov. Each tree in these situation I take his lead.

 

I posted up as to guage the general consensus from the more experienced cutters out there and to see if anyone had seen or used it before.

 

Matty, I reckon your point is worth noting as sycamore is quite brittle, (these were anyway) maybe it did give a little more holding than a conventional hinge would have.

9 out of 9 is good enough for me mate. I shall give it a try next time, i never took the width of the hinge into consideration, makes sense:thumbup1:

[Rich Rule]

by width of hinge I meant diameter as opposed to thickness...

[Stephen Blair]

thats what i thought you meant mate:thumbup1:

I was meaning that if possible you could set a redirect block high, in cases where you can only set a low pull line because the trees have an enormous lean, say woodland edge trees that have grown out under something else, or like your trees, where the top is unsound.

 

If you can pull from any sort of height, either with a redirected pull line or from up a slope. it can make a huge difference to what you may decide to pull over, or not.

this is the tree i felled by the burnside, i left my nearside a bit thicker to ensure it didnt go down the burn.

Another one from today, not my best.
