    Request: end line knot for heavy loading

    In my personal experience, I've never had a Zeppelin bend jam. I have seen many instances of falsely tied Zeppelin bends (where the person thought they tied a Zeppelin but in fact tied something else). Tying knots is a skill - and like all skills, it takes deliberate sustained effort to reach...

    Overthinking, a Minimal Friction Hitch model

    Thank you for your post TheTreeSpyder. In the spirit of the title of your original post - a minimal noose hitch is the 'Gnat noose hitch' - or my own modified 'Gnat 8 noose hitch'. Refer to images below. These are 'noose hitches' - which is a distinct subset of 'hitches'. Noose hitches form...

    Tying climb lines together

    Hello 'TheTreeSpyder', RE: Your post #25 Your image of a 'Riggers bend' is incorrect - thats not a Riggers bend. However, it is an interesting structure that I am right now investigating....might be worth your while posting on the IGKT forum to see if its an original creation of if its...

    SPRAT (for a climbing arborist)

    Hello COtreerat, 'Rope access' (ISO 22846) is a very specialized form of working at height. The ISO standard requires the operator to be attached to two (2) ropes at all times (or anchored to 2 independent anchor points at all times). For example, during a rope access assessment (either IRATA or...

    Assessment standards for arborists (climbing trees)

    I am presently conducting research into various national competency standards for assessing arborist tree climbers – beginning with my home country (Australia). So far, the picture is fairly grim. The industry as a whole does not have a great public image (in Australia) – eg when compared to...

    Will a larger rigging ring always make more friction?

    Hello 'The TreeSpyder'. I can see that you are very passionate and want to share that passion with others - which is a very noble cause - and I thank you for such efforts :) Some feedback - which I hope you will receive in good faith! When I read your post: I tried to make sense of the...

    Rope strength question

    The MBS yield (ie strength) of the #1053 Butterfly is irrelevant. People use a Butterfly because it is jam resistant (in biaxial through loading profile), its 'TIB', it can exist mid-line, and has multiple loading applications. There are lots of eye knots that have similar MBS yield (but again...

    Clove Hitch

    Hello Kevin? (you didn't introduce yourself in the video...) Thanks for producing and sharing your video it is appreciated. Just giving you some feedback in good faith... at 0:15 A Clove hitch is 'TIB' (Tiable In the Bight). The definition of TIB is that the knot structure can be tied without...

    Rope strength question

    This is actually a nebulous concept. There is no load that a single climber (in the act of climbing and being mobile in the tree canopy) can generate that will reach the MBS yield point of (any) knot. What is more important (with hand tied knots) is stability, security and resistance to jamming...

    Secure, omnidirectional quick release hitch

    Hi John, I've attached a quick photo analysis of your creation. I am quite impressed by this hitch - and I think this demonstrates your creative genius. The hitch is fundamentally based on 3 slipped #206 Crossing hitches (ie Munter hitches) which incorporate 3 interdependent bights. I still have...

    Secure, omnidirectional quick release hitch

    Thanks John JRB. Am likely stating the obvious here - but: Any would-be testers need to have the test parameters defined. If the test parameters are not strictly defined - the results will not be reproducible by others. In the 'scientific world', results are published by various...

    Secure, omnidirectional quick release hitch

    Your command of the English language is impressive rico! Have you anything positive to contribute with respect to the 'JRB hitch'? You obviously feel empowered behind your keyboard - and probably think the moderators will not take any action to warn or ban you? I presume that because you likely...

    Secure, omnidirectional quick release hitch

    Hmmm. You should receive a warning for that. Total disrespect and childish, immature behavior. You obviously feel powerful from behind the safety of your keyboard? Do you have anything positive to say about the "JRB hitch'?

    Secure, omnidirectional quick release hitch

    Thanks for your good work John. I agree with your concept of isolating your hitch (for now) from life critical applications...which should enable unbiased opinions. I apologize for the disgusting behavior of DSMc - he clearly is a troubled person who needs counseling. He appears to show no...

    Secure, omnidirectional quick release hitch

    Contact me in private DSMc instead of posting nonsense to the world at large. Do you have any constructive comment to make about John's hitch? I think it has merit - and I applaud him for making a solid effort to bring it to the attention of others. On the other hand, DSMc appears to make no...
