Still wouldn't happen for me Ben because I don't have an account. But good to hear nonetheless.

Yeah I'm delighted. Wouldn't happen on Facebook.

No worries Sean. Thus came in the mail today....off the back of some earlier discussion in the thread. Just like that. Many thanks to the sender. It is much appreciated and will not be wasted on me. :beerchug:

I recall the second line was just to control the speed and haulback Sean. It may have helped with the balance, but those low limbs were mid-tied to balance anyway. Thanks

Thanks Rog Chris. That setup has its place. It worked well enough on that job because of the clearance issue on the lower limbs in particular. Both lines were being tensioned and controlled from the dual bollard at the bottom of the tree, hence the pulley/redirects up top. If the tree had been...

Thank again guys Magnum. Welcome. There's a new members thread in the announcement forum. You just introduce and say a few words about your situation. Everybody does when they join. The rope is teufelberger 16 strand I think. Could be 10, 11 mm. The slings are 8mm, SWL about 500lb....and 26in...

A bit of both really Sean. Either way I view the back limbs in this case as creating some resistance to movement there. On some trees, short ones especially, it's hardly going to make any difference. But on those types in the videos it puts a little extra something in your favor. There's no...

I think theyd have to be an enormous amount of weight for that to happen....or totally saturated ground or something. Hydro have been siding trees for decades, but you rarely see the trees fall over. If a tree is already showing signs of a defective root plate, then youd probably strip the limbs...

I didnt really persevere with it Dave, to be honest. I tried it with the beeline (I think) that came with it. Which I felt was too short anyway....and then core started to disappear into the sleeve within a few hours. And I just thought, fock it I dont have time for this now :) .....And, I...

I tried the HH a few times Sean, and it performed well. I never liked that the whole thing depended on two little stopper knots though....especially if youre taking it on and off. I never found issue with the RW, so I stuck with that. We suck up slack on ziplines to gain clearance, not so much...

That'd be nice Dave, but my lines and hitches are constantly pitchy. Not much you can do about it.

Thanks Dave. Nah I much prefer shouting over the noise of the traffic, chipper and saws ! Yeah I could see the benefits on certain jobs. What is a HUT ?

Thanks all Sure Gary. It's not so easy to simulate with a short light section. But imagine the leverage of a butt-tied 15 ft limb pressing into the line. Works just like a cam.

You might have caught the the previous zipline vid I put out a few days ago. I was back at the same job on monday, and got the inclination to video and explain some of the considerations I have when applying the technique to the tall skinny types that are in the vid. If you're having to deal...
