Let's see your twin rope system..

Far too complicated for a knot Luddite such as myself Ben.

 

Ill stick to my single line thanks.

Just smoosh a bowline and VT together Rich! Surely even you can get that?! hah hope you are well amigo

Sorry Ben, but you’re at least the third to discover this hitch.  It’s recent name is the Penberthy, but it was used in caving years before as the Helical Hitch.  The hitch has the problem of the Bowline tightening when loaded, causing the added slack in the wraps to not grab.  Bob Thrun came up with a variation that helps to lock in the wraps tension better. Bob’s on top and a slight variation.

I’m still not seeing a benefit and a still shot does not make a working week.

sorry @BenR ?

it’s more complexity to what was and is a simple and safe way of operating using a single line securely attached and operated.

And you know I agree with you Marc, but the post was to help those who perhaps feel the need to comply.. 

 

Brocky, it looks different to me, but i'll take your word for it. Also very similar to a helical.

We are complying though, and as you say you agree, twin rope is not a good mandatory stand point and should only be used if required, so for those Snapshot moments where two systems would beneficial it looks good.

This may help someone hopefully, in light of the whole "backup" talk...

 

The hitches are a strange mix of the bowline and the Vt.. i'm going with 'BT'.

 

They can be used single leg or the systems split apart and utilised in a more conventional two leg hitch. I find when they are joined together on the one carabiner I can operate both one handed easily enough.

Is the still one anchor though @BenR?

[Brocky]

Sorry for the unclear post, the above two hitches are variations on what I think you are using which is below.  The small loops are showing the different ways the loop, or nip can be formed, basically you get the same results, with the ends in different positions.

I first saw it in a book which only used a cord for the illustrations and I mistakenly assumed it was a double eye hitch and used it that way for a while.

I had to remove this ash tree over a reservoir spillway yesterday. The tree was suppressed so no high anchor point. I used a taller Alder from behind (with the lowering bollard on) as an anchor for both ropes and the rigging block. My anchor points chosen were two cambium savers block knotted for srt use. I then traversed over to the ash via the Captain Hook and installed a static redirect for only one line. This then allowed me some triangulation to move around the canopy. Definitely took longer in the set up time but not to bad. Overall was around 3.5 hours from set up to leaving site.


 

All looks very professional lumberjack but if you don’t mind me saying very much over kill for that particular job...and i mirror what Mick said...I would have thrown a line over the branch you are anchored onto and pulled a small rigging or old climbing rope over it with a spring carabiner on the end,wrapped round limb  were you are standing and pulled rope right so the biner runs up and holds tight against the limb and used a pole saw to make a small cut till the limb starts to fall and then pull in..not knocking how you have done it and great double rope set up but as they say there are many ways to skin a cat and I reckon you could have saved yourself a couple of hours.
