    Tests of Zeppelin vs Double Fisherman's bends?

    Ok, I am an engineer by career and so i GREATLY appreciate the level of detail in your response. Thank you. The attribute you mentioned about being TIB ... this was the subject of my thread here just a week ago (Single Guy Seeking Sexy Friction Hitch), where i am looking for a TIB Friction Hitch...

    Tests of Zeppelin vs Double Fisherman's bends?

    Many thanks for posting that. So 3267 lbf for Zeppelin vs 4100ish for Double Fisherman's in this test... not an insignificant difference but stronger than figure 8.... and my selfish question is if a 7mm prussik loop closed with Zeppelin is safe for half of my weight, in a doubled rope system...

    Tests of Zeppelin vs Double Fisherman's bends?

    Is anyone aware of strength/efficiency tests of a Zeppelin Bend vs Double Fisherman's? Yeah, I know, prussik loops shouldn't need to be untied, but I have a legit reason to do so on occasion, and breaking a double fish is awful, like ending a bad relationship... Yes, i know a stopper knot can be...

    Correct buddy, i am sliding two identical friction hitches up both sides of a doubled but stationary rope. Basically, the rope is set up like an MRS / DdRT / Blake's hitch climb would be, but i climb both strands at the same time with no movement.... and here's a funny story... last night, like...

    There's an old rule of thumb that prussik cords should be 60-80% of line diameter, however, we are inventing knots here and there are exceptions. Bachman is a friction hitch that works better at a 50% difference for example. My experience with Michoacán with a loop was similar: 50% worked much...

    On sunday, i did a bunch more test climbs comparing a standard Michoacan to ANYTHING else, including Michoacan tied with a loop, and standard Michoacan is still the best. It's simply can't be tied with a factory sewn prusik Loop. I do appreciate all the replies, as you guys are awesome! I may...

    The Zeppelin bend...

    I realize this is an OLD thread, and I can start a new one, but the question remains: has anybody done formal testing of the Zeppelin bend, as compared to the double fishermans for example? I am using a Zeppelin (with long tails) for life support and have never had any slippage of the tails...

    I climbed at least half a dozen times today on both the doubled distel and the doubled michoacan, meaning that i tied them with both sides of a doubled prussik loop, 5mm on 9.5mm rope, and the Michoacan was the winner. Easier to move up after loading removed and much easier to break under load...

    Rope a dope, I like your theory and was thinking along the same lines. Tonight, in the basement, I tied some of my favorite friction hitches simply treating my doubled loop as if it was a singe cord, so everything appears to have twice as many wraps. The key was that because of all the extra...

    Ok, so i have some 5, 7 and 8mm Sterling accessory cord and my newest climbing rope is a 9.5 mm Sterling Super Static. The Michoacan is very smooth with 7mm cord. The newest Creation below, Distel with a loop is tied with 5mm. Its thin but my body weight is on 8 strands, 4 per Distel and one on...

    NJDelaney, yes, great suggestion. i have already considered that failure mode and have to address it. Or literally frozen in place due to rain and ice.

    Single guy, seeking sexy friction hitch...

    In parallel with some of the suggestions above, i was doing some experiments myself in the same direction and the one that seems the closest to the "sexy hitch" i am looking for is this one: its basically a Distel, tied with a loop, 3 turns instead of 4, and ya clip in on both sides. Its pouring...

    Yes, but has potential for other systems, but not likely for arborists, who are much more likely to invest in pro devices. We have people doing some crazy things with ropes and steps and DIY aiders and I am doing my part to introduce some safe techiques. In fact, I literally just got in an...

    That's an interesting contraption, but mine is not an invention or device, its a method, and is dependent on two, identical friction hitches, for life support which move easily after loading and which can be broken under load fairly easily. I can slide both of these Michoacans with one hand...

    Millingtons seem like they CAN be tied with a loop, but not midline, as i need the end of the Rope to pass thru my loop. That's fine for my application. I tied em all and the regular Millington seems best. I will do a side by side test in a tree tomorrow. Ps, my attempt at a DIY doesn't seem to...

    Every time i think i invented a knot, it's already gotta good name... but I did come up with this just now. It can't be tied midline tho, cuz you pass the end of the Rope through the cord Loop. Tie it like a blakes, but 3 ascending wraps instead of 4 and of a loop, not a line, a short tail...

    Jonny, I am new here. Just yesterday, I posted a video of it on a private facebook group, explicity for peer review with a few experts, which are hard to find on Tips and Tricks... i got more attitude, and a few experts. If you wanna see the entire climb explained, i will show it to you, and...

    Thanks; this is exactly the kind of thing i needed.... i need to try these.... of course, for the last 2 hours, i have been 'inventing' some of these for the 1000th time in their history. one has me excited though.... i will post a pic when i can later.

    Rope-a-dope, Check your first sentence there: I believe THIS is true: We can tie any friction knot that is ordinarily tied with a loop and simply fashion it with a loop from an eye to eye. But you said the opposite case, saying we can treat a loop like an eye to eye. Actually, because of the...
