tripping a hung tree

[Bolt]

although CS31 covers hung-up trees, Windblown trees are a different matter because whereas a hung tree has an almost totally severed stem prior to getting stuck, a windblown tree is couterbalanced by not only a soil covered rootplate (that can weigh tons), but also the spring exerted by the unseverd roots that are bent back on themselves.

 

If a windblown tree is dealt with a long time (I.E. years) after it went over, you will find the rootplate is often quite happy to stay stuck up in the air. A fresh trees rootplate will return to its place with a force, often far greater than just gravity.

 

This is why organisers of windblown training courses, and CS34 asessments will require freshly windblown site.

Not at all...

 

its like bucking a downed tree. You don't even have to think about which way to make the cut, you've done it so many times, you just know where the compression and tension will be. Its all pure physics. Not at all unpredictable. It becomes second nature.

 

What makes a hung tree any different? The forces involved may be slightly more complex, but it is all still pure physics.. Nothing unpredictable about it. If you understand the forces and have had the experience to see them in action, then it becomesl very predictable.

 

Are you for real???????????????????????????

What are you, dadio? Chinese?

Dadio is now famous in my eyes. He is a true star of the timber falling world. A renegade. A maverick if you will. Long may he continue to cause controversy. Long may we continue to enjoy, discuss and argue about his way of doing things.

 

 

I like him.

Dadio... I put it to you that you are, infanct, an eejit.

 

 

 

A spade is a spade in my book..

SO here's a question for you all...

What is the one situation where the butt will not drop straight down?

QUOTE]

 

When the tree is stuck/jammed. Multiple windblow. A lot of side tension. When the trunk is almost level but the crown(tall skinny trees)is bent upwards.

 

So then since this is not one of the scenarios you cited, would you agree that there is no chance of the tree coming back towards the faller (me) in the scenario of this video?

 

ps.. thank you Darren.. I agree nothing wrong with a bit of controversy and the ensuing dialogue

Only tried that technique once after being advised by a tree surgeon friend that it was the best way to deal with a large windblown alder in a wood, obviously slightly different as I'm not a climber so did it with the crown intact, back of the tree broke out first even though I'd left plenty of meat when plunge cutting it, barbers chaired about 7ft up from the plunge cut twisted round snapped off and slammed into the ash tree 3ft from my left ear at head height at some considerable force, fair to say if I hadnt been behind the tree, theres more than a fair chance I wouldnt be here now, so no I wont be using that method again

Sorry, this is now a quote within a quote within a quote which makes it look like I asked for scenarios where I didnt.

 

I replied to the above saying that the butt will not fall straight down when tensions and compressions could not be accurately predicted.

 

I would agree that you can make an educated guess. But it is still a guess at best.

My child is a genius.. literally off the charts.. he broke the school districts all time record in reading last year.. We'd like to get him in a better school, but there are none available in his area.. mioght be a good metaphor...

 

 

maybe you could get your child to teach you how to spell,,,,,

 

FWIW,, how come you state it's a "safe" method yet you have pages of warning's and disclaimers at the start of the video,,
