FWIW, I do not like to use severe pruning except as a last resort. I would much rather install some cabling than top a tree or remove large limb wood.

I disagree, You tie your own knots, why not learn how to splice? It just takes a little research on theory and methods and a little practice...
I'm not sure I totaly understand the statement you made. Are you saying that the tree will tip towards cut roots? It has always been my understanding and experience that roots hold the tree upright with tension, not compression. Therefore a tree will fall away from damaged roots.
Right?
Dave
The only problem I see with this knot is that the timber hitch requires a choke to load the knot properly. By putting the bowline in it you are removing the choking action and not allowing the coils to properly share the load.

... trying to figure out the logistics of where to hang it. (i.e. how much of an angle should be created between the trees?) We know that the force on the rope changes a lot, we're just trying to be able to calculate it. (Particularly so we can make sure the rope and the anchor/tree...
One last thought.
When setting up a rope zipline. Set the tether so you can reach the rope (not for the kids, they should not be able to reach the rope) so you can test it. Wear heavy gloves to break and go slow first and progressivly pick up speed so you can see how far you will go and how...
last one. This is the start of the picture in my avatar. Funny / scary story goes with this one depending how you look at it.
The location was just outside of Bragg Creek Alberta, kind of an out of the way spot on the way to some ice caves. We had set up and doen this here about 5...
this is a picture of the zipline on a 10 element ropes course I used to help run. Cable line, telephone poles for anchors. This was put up by an ACCT member company called challenges Inc.

here is another system in the same area. The bridge was the anchor on one side (figured it would hold) and it went 250 ft to a tree 50 ft lower. This was a fast ride but it was tied high enough in the tree so you would be going uphill at the end and gravity would slow you down. you would then...
here is a picture of a friend and myself over a decade ago. The rickety deck chairs are tied in with webbing but take heart that we are wearing harnesses and are tied into the zipline rope as well.
This was neat because it was a hot summer day and people come a long way to cool off by walking...
for us to set lines on the big ones, we sent one person up one side with the mainline and another up the other side with a rope long enough to make it to the ground. mainline guy ties the anchor and rappels down, walks the end of the line over and ties it to the bottom of the other rope, which...
If you are doing this in different sites, rope is the way to go. How is your liability insurance for this? In Canada they would not insure something like this at all (having tried).
Your sites have to be pretty specific for the ideal zipline. You don't want to hit the ground at any sort of...
Skew,
these guys are being pretty hard on you. I got your back man.
Safety regulators can find something wrong with EVERYONE if they want to. So be careful about casting the first stone. Karma's gonna catch up with you. As an example, in Ontario it is required to have manuals for ALL...
