    Knots for joining two ropes for life support

    Moss- I m happy for you to be content with the default mindset of 'slow-pull-it-till-it-breaks' mindset. I am also happy to make the distinction between the 3 forms of fall-protection systems: 1. Travel restraint 2. Positioning (or 'work positioning') 3. Fall-arrest. It is patently obvious that...

    Knots for joining two ropes for life support

    My statements are specifically addressing the default mindset of 'pull-it-till-it-breaks' - and the relevance of doing this. If you take a snapshot of all of the knot tests performed all around the world - they invariably all run the same theme; 'slow pull-till-it-breaks'. There appears to be no...

    Knots for joining two ropes for life support

    I disagree completely. The MBS yield point of a knot does not tell you anything meaningful UNLESS you are specifically investigating a geometric change or assessing if the knot remains jam resistant right up to the point of failure. And you must use a 'control' - otherwise, your tests are...

    Knots for joining two ropes for life support

    Thank you Brocky :) For other readers absorbing the technical aspects of this thread, I should point out that I do in fact appreciate the work Richard Mumford has done. However, from a pure research point of view, a lot of knot testers around the world fail to use a scientific 'control'. The...

    Knots for joining two ropes for life support

    This is an example of a source of misinformation because it is unclear as to precisely which knot structure is being referred to. A lay person could misinterpret the meaning... 'Retraced F8' could mean either #1411 (Flemish bend / F8 bend) or, it could mean Offset #1411. If #1411, it cannot...

    Knots for joining two ropes for life support

    The MBS yield point (ie Strength) of a knot is irrelevant. There is no load that an individual climber can generate that will reach the MBS yield point of a knot. I'm assuming that the type of ropes used will be human rated - and intended for life critical applications (eg conforming to EN1891...

    Favourite knot(s) for connecting 2 ropes for heavy loading

    I would be most grateful if you could post a picture of the Zeppelin end-to-end joining knot that you tied please (ie the exact form you tied that you found to "seized right up"). Just tie the bend as best as you can recall from the date you found it to 'seize right up' - and post a picture...
