/ Obscure Knot
Also, it will be utterly irrelevant to 'normal' climbing situations but any knot-geeks may well be in a headspin when they read about this 'cause it's not (pun intended) in any book, that can find, and it was simply passed down from one M&AW staff to another and may be lost in the mists.
Is it anything like the Dolly knot or truckers hitch? both tension without the need for any clunky metal bits.
here's a tensioning knot - what are you using it for? Slacklining?
Interestingly a guy called dix has written a book all about knots:
You've mentioned it's a Marine thing- are you sure that this is pukka-no-wah-gen?
There are lots of variations on the general theme of tensioning knots but all the ones I've used seem to be pretty harsh on the rope. Most involve creating a sort of heath robinson z-pully using bights in the rope. I spent some time helping out an a friends parents farm and by the time we'd secured the trailer full of bales using a series of tensioning knots there was more blue poly rope fibers on us than hay!
I have used it but my problem is, as you can read, I have lost all knowledge of how it was formed (not that there will be a likely situation for its application or use) and in a field test we had a Discovery on full torque pulling a tied of climbing rope: there was no rope deformity.
The fun bit was putting a piece of hand held, tightened cord against the tensioned rope and after three rubs it ripped the sheath and leaving only a few twines of the kern.
I'll keep searching, Andy
Trucker's Hitch is here:
Thats different to the one I was shown back in the day, but the same sort of thing.
mine goes like this
take a small bight of rope ~2-3" a couple of feet from you attachment
create a hanging loop by coiling two turns of the tail around the bight
pull another bight through the hanging loop, (a-la daisy chaining a rope) hook this bight over your attachment point
pull on the tail to tension and secure with a few hicthes
That's Americans for you....
That site also has the handcuff knot in their section on rescue knots. I'm a little uncertain of its application in mountain rescue!
