There's only one way to find out.......

Not arguing by the way, just want to make sure I fully understand the principles behind it! Explanation appreciated!

True, but presumably a large limb with say 400mm of rope in contact with it will exert an amount of friction on the rope which will reduce the force required to resist the force, the same principal as using friction to lower cut timber....? And I guess a smaller diameter limb would create less friction requiring more force to counteract the exerted weight. Only over a friction free pulley would the force be the same both ways. But I would still have thought half the exerted force, the main principle behind ddrt?

Presumably the amount of friction around the limb will affect the amount if force necessary on the opposite side to counter act the force from the climber?

Just for my own curiosity, can someone do the maths for me? I just can't see how it can be the case.... Secondly, is there a necessary clearance and minimum tether length for the rw to work? I've been browsing all the off the shelf stuff as a starting point and the best stuff I find is around 20 / 25 cm... Is this too short...?

Deja vu.... :lol: How much was it....? I still prefer the rw concept though I reckon....

And there was me thinking it was the 'SCAM ITEM, ACCOUNT HACKED' title....!

Ooh now I do fancy a uni.....!

What makes you think that.....?

You could launch yourself up with that lot Dan..... I tidied through my gear yesterday, made a list of the next tranche of purchases.... RW is in the shopping basket, do I don't I.....

Without seeing it i have no idea really, but in general it depends if it could hit something, always better to have control. Rather than having a free flying tag line you could control it yourself through a friction hitch. You've got a haul back line then as well..... Depending on the angle and size of the bits you're dropping you could lock it off with a prusik rather than portawrap....?

Interesting..... Another nail on the zig zag coffin for me....

I believe zigzag, bulldog and unicender can all be used in their own. Spider / lock jacks need additional friction management....

I concur....

Tempting, very tempting.... On the birthday list I reckon....

Both Chris, depends what I'm doing. Both my current strops have vt's on them, one is 9mm boa, super long one which i also use as a second line now has 8mm OP, both on isc micro pulleys. I make strops up regularly out of odds and ends I find lying around.....! Cheers Paul, I might give one a go...

2 things.... I'm making up a new lanyard (as discussed elsewhere... ) and I think I've settled on 5m of 10mm OP with 8mm Sirius or similar... For now I'm going to hold off on a cinch. Any who, I dislike clutter, particularly on my bridge, so rather than a micro pulley like I have on my other strops, I'd like to use an hc or skywalker so I only have one krab on my bridge. I like my hc but it seems a bit over the top for a strop and quite bulky, so I'm thinking of trying a skywalker. Does anyone have both and could you post a photo of them together so can get an idea of any difference in size? I'm hoping the stein pulley is smaller..... Second....best solution for base anchor? I tend to use plain ended cut lengths of rope for everything, but I'd prefer something a bit more purpose made to attach my new static rope to the bottom of the tree. The cheap and cheerful solution is a length of 16mm bull rope..... What's better....?

You might drop lucky and find a MS460 for that, if not maybe an 046...... I love my 460, 25" bar, great saw..... I sold a nice 460 for a shade over £300, but it was a nice one. You ought to find something a bit more tatty within your budget....

Good call! Sacked the saws off the bench, time to wax the base and polish the edges!

I'm in a similar situation, but I just can't help myself, I love having the gizmos....! I spent a few quid on a closed hitch setup comprising hitch climber rapide, 75cm Yale beeline 8mm eye to eye cord, pair of DMM Ultra o crabs and a multi-saver, it's a lovely way to climb. Just got a pulley saver today to replace my practically unused multi saver as well..... Would recommend it. Going to order a rope wrench now so I can use it for SRT as well....

Where do I start....! Camera SUCKS BIG TIME. Battery life stinks. Call handling and signal retention a bit hit and miss. Tiny memory Grossly overpriced.... I could probably come up with a load more in the morning.....!

I'd like to do a db one if the dates fit Nod....

I have ipad mini 3G. It's ok, does a lot, I use it all day but it hasn't saved me anything, just means I spend more time staring at a screen. Also have iPhone 5. Rubbish. My favourite is my laptop, 17" vaio. Does everything, properly and well. And because I have to get it out and set it up I only use it when I need it. Get a small cheap laptop / net book, much better solution.....

I asked the same question a couple of pages into the rw thread. Essentially a normal friction hitch from ddrt running in a single line is subject to twice the friction which could burn it out. Rw splits the friction between itself and the hitch. Kev calls it the limb which goes with you, it's 1:1 climbing with the friction of 2:1. Genius!_

Doh! Did he say static? I thought we were talking about dynamic! I can be a proper space cadet sometimes..... In that case I have no idea....! Too much heat in the event of a fall I imagine....?
