Wow!!! That was incredible! I've done some hairy trees, but that looked just plain crazy. Is there a story to go with that vid?

There probably is but I don't know the story. That was one hairy scary tree.

The kind of tree that gives you nightmares the night B4 climbing. Amazing!

That's hardcore! I like the set up they used with their rigging lines. Don't think I've seen a set up like that. Anybody familiar with how they rigged it?

I have been playing on google earth looking for the Tahune Air Walk. Found it. Look for the Huon river, Tasmania.

looked like multiple guy lines and double rigging points maybe

Funny, but I really liked the soundtrack. Beth Orton is the vocalist, and her fragile voice is a great juxtaposition to the vid.

Camera work wuzz FREAKING FANTASTIC!!
Watching him work that rotten stick I learned something I will use on a tree coming up in a couple of weeks.
VERY COOL!!

Yes! & just the reminder from watching him, To Stay Smooth.
Do what I do & dont hurry it.

I like the sound track also. It added to the surreal air that the camera so greatly captured!!

It looked like a pendulum swing drop on some of the pieces that were rigged off.

Similar to what Don Blair, Ken Johnson, Robert Phillips and Mike Majors did on that big leaning redwood back in 2001.

It helps to reduce the shock loading on the line by swinging into the drop rather than just dumping the pieces straight down into the lowering line.

I did that once but it was to move the pieces closer to the truck. I never thought about the reduction in the shock load.

How do they keep the pendulum from swinging back and nailing the tree?:?

Yeah, I'm not really clear on how that's set up. Could someone please explain it a bit more clearly?

He's using two lowering points, which limits the swing, and allows the limb to lower to any spot in between the two points.

Anybody else ever have to guy a tree first before climbing it? I did for the first time this summer. It was big doug fir that had uprooted and then got hung up in a nearby maple. The truly scary part is having to climb the thing first to set the guy lines. It looked like he had a live tree nearby to set his line in though. I bet that job paid pretty well!

I guyed this with a chain a few weeks ago...the chain got tighter by the time I came back to take the tree down. Once I had the limbs off the tree, it stood up and the chain got loose.

Willie, there is a very important point in what you say...if it WAS necessary and you didn't take the precaution you would be telling a very different story.

Sometimes knowing when something is truly necessary is an art as much as a science. When in doubt, do...it takes longer but may be "necessary".

What I sometimes do to guy a dangerous tree that I have to climb and work in is to use my throwline first, then pull my rigging line up into the limbs or target crotch that I'm using to guy. Then I tie a running bowline and pull it up into the tree and anchor it to other trees or ground anchor if necessary.

You can do this for as many guys as you need and then feel alot safer climbing into the tree.

First, I have mixed emotions about posting a personal video in a thread with Graehme McMahon's name in it...he is a master in the rigging field.

But, this simple video does answer Newfie's question...this is how we did it at Katrina. Some of you guys have already seen this.

The first piece was near the end of the spar and was belayed to control the pendulum-y swing. The second piece was in line with the rigging tree...it definitely bonged the anchor tree.

Google video made it pretty splotchy.
