work wuss i'd agree with what your saying i think your both confusing each other. its the same formula for when calculating becket loads on cranes. 5% friction is included with the equation(thats going through pulleys) this is dynamic however but still bares relevance. you will have less forces on the opposing side of the climber if you've applied the weight with no force. you dont need 100kg to counter 100kg when over a branch. once you've jumped around a bit though the forces will equalise as you've applied extra force from the climber side. obviously this all only applies if your directly below the limb(angles change everything). if you put so many wraps around your top limb it then almost becomes a top tie in point. put enough wraps the force becomes almost x1 on the limb.

I wondered as much! Thanks!

does everyone not just whistle over the fat groundy to test the base anchor??

we always test our base anchors with two bouncing, had to rethink a couple too!

That's it, I've finally done it, I've ordered a rope wrench....

(And a few other bits including stuff for a new lanyard....)

So knowing Justin's service that will be with me on Thursday....

 

Excited much!:thumbup:

Good idea.... I'll see you in a few days!

Interesting.... Just over a year ago on page 2......

 

 

I'm highly unlikely to venture into SRT, I'm quite happy on Ddrt and the cost to swap to SRT is quite prohibitive for me, but I am fascinated by it.
