ratchet knot

Post by lj »

I'm being lazy and hoping someone can answer the question rather than me spending ages looking - I have tasks to complete before My Lady gets home :shock:

is there a simple way to make a "ratchet" either from rope or very simple items. I'm giving a demo on predicament bondage at a party next week and I like to keep things simple, not use complicated methods, so anyone can do what I demonstrate.

The scenario I am after is to have the subject tied, not important exactly how all this fits together, but that if they move, a rope tightens. I can use the sort of rope ratchet that the sailors use, a pair of serrated "cams" that close on the rope, preventing it returning, but allowing free movement in the other direction, but this means getting a piece of specialist kit. A weight or bungee cord would provide the "pull" against which the subject must resist, to prevent the rope being tightened.

I have the idea there is something using a couple of metal rings, but even this requires the rings to be available, though I probably have some if that's the only way (and someone can tell me how to set it up).

The rope at the top is connected to a fixed object...
The bottom rope loop, one goes to a counter weight (a weight is required )
and the other goes to the victim... aaa. volunteer...

Altho, and it is a thought... the volunteer could be connected to the top rope,
weight to one and secure point on the other...

I did read a story abut a girl that used ratching seat belts.
They would take up the slack and provided some tension, and would only release once the belt was fully retracted...

That's the one ! Thanks.

Will look for suitable rings and try it out. I'll use either a weight or a bungee cord, depends on what anchors etc are available at the party.

That looks the same as "ring device". I first learned about that from this very site, in the basics section

I think that a "tautline hitch" is what you need.

Very nice knot, I use it for a lot of purposes.
