    descending from the ropewalker - new guy help?

    [ QUOTE ] Locking off a mini-rack seems to be tricky. Any pics of a mini rack locked off properly? [/ QUOTE ] One really neat, simple way is to use a prusik BELOW the rack (on the down line). Tie the prusik securely into your harness somewhere. IT IS IMPERATIVE THAT THE PRUSIK CAN <u>NOT</u>...

    The Zeppelin loop vs the F8 in pulls

    [ QUOTE ] Hey, thanks Ron! You tested two knots, but have shown us only one of them. We must wonder what <u>your</u> Fig.8 eyeknot looks like. (The unfortunate presumption is that "F8" says all one needs to know -- just go look it up, um, here or there or ... .) [/ QUOTE ] The F8s were F8s...

    The Zeppelin loop vs the F8 in pulls

    [ QUOTE ] Nice work, Ron! That nice tight grouping in your results gives great confidence in your numbers. It's also good news. Now we have a reliable and strong loop knot that is super easy to take apart even after a huge load. Now if I can only figure out how to tie it... Did you notice any...

    The Zeppelin loop vs the F8 in pulls

    What an interesting test! I pulled an F8 against an F8 tied in PMI 9mm (I had formerly posted 10mm; it was in fact 9mm)EzBend to get a baseline and one of the F8s failed at 3465 lbs. I think that's a bit low, but.... This is the version of the Zeppelin loop I tested: I then pulled a ZL...

    descending from the ropewalker - new guy help?

    Perhaps the simplest, most straight forward method, is to install a DdRT setting with the other end of the rope. Take a stroke or two to get slack in the ropewalker and remove the ropewalking gear. Install the rack and lock it off and here's the why of the DdRT setting, you can then lower...

    Gonna be off-line for 2-3 days....

    My wife and I are taking a little time off. We've had a whirlwind summer so far - nothing like what I was expecting. Saturday morning I went over to Bruce Smith's house (On Rope owner) to help him (more like so he could help me) take down a dead tree. We had to rig it and lower it, thankfully...

    The Zeppelin bend...

    Re: A baby experiment moray Briefly, mainly because I'm 'time-challenged' today, with regard to both your last posts, I pretty much concur. When I tested the F8 bend against the ZB, I got 66% and 63% respectfully, in 9mm PMI rope. I don't even consider 3% enough to claim a difference. The...

    [ QUOTE ] Any pointers with 2 splices?!? I've just started using 150' double spliced... [/ QUOTE ] Ronbina, I've noticed in the past, that catalogs i.e. Sherrill Tree, etc. advertise double braids as spliceable only on one end. Now, in Sherrill's latest catalog, they offer splicing on both...

    Forces on lowering devices

    [ QUOTE ] In a static load, the block, if the rope angle is 180*, would see approx. 2X the weight of the load. The rope friction device, at the base, would see approx. 1X, if the rope were running over a sheave. Natural crotch rigging would be different. These are approximate weights only...

    Revolver for a friction saver

    [ QUOTE ] Drll out a slightly bigger hole in the ascender and the revolver fits just fine. The pulley and new hole are not holding the weight of your body. Don't know how "legal" this is, but it works great for me, smooth down the sharp edges after the hole is drilled and your good to go! [/...

    The Zeppelin bend...

    Re: Break-testing the loops [ QUOTE ] [ QUOTE ] ...66% seems a bit low for an F8 bend though. That would suggest that the break strength, 63%, of the ZB may be a bit low too. [/ QUOTE ] I never tested an F8 bend, but I did break some F8's on a bight. The stresses on the rope won't be...

    The Zeppelin bend...

    Re: The Zeppelin bend... SOME THOUGHTS I am pleasantly surprised at how many people use the Zeppelin bend - and everyone so far has had very positive experiences with it!

    Footlocking technique...

    I'll try the sneakers. I think I'm close. The test I've been using is to try to lift myself only with my legs and the footlock. So far, I can't but as I said, I'm close because with just a little help with my arms I go up. My feet are 90°; I'm just wondering if there's something I'm not quite...

    Revolver for a friction saver

    I'm sittin' here looking at a wire-gate revolver and an ABC ascender - very similar to a Petzl Ascension. I can find no way to rotate the wire-gate revolver through the two holes at the top of the ascender. Even if it would rotate through, the ascender is so wide and the Revolver is so narrow...

    Revolver for a friction saver

    I don't see how the wire gate version would fit in the top hole of a typical handled ascender, e.g. Petzl Ascension. You can put the wire gate in a bottom hole, but that puts it much lower than a pulley in the top hole. A biner and a pulley cost about the same or less than a Revolver and is...

    Footlocking technique...

    Just got back in from another try - I can't keep the rope from slipping. I tried several different things but when I press down on my legs, I can almost lift my body - but not quite. With a little help with my arms, I can go up the rope, but it is tiring. My arms don't fatigue - I just get tired...

    Footlocking technique...

    I'm not sure it was a total derail, he did ask about footlocking - anyway good move to start a new thread. Good stuff Blinky. I can see that this would be a really good way to enter a tree if one can get the hang of it (no pun intended). With the short trial climb I did moments ago, it seems...

    a few questions for you guys..

    Ha! I just hope I can get off the ground! Ok, I'm pretty much set up; gotta get the ground cams in place - we won't want to miss this!

    a few questions for you guys..

    I'm gonna start out with a Petzl AscendTree backed up with prusiks. At least I'll have something to hold on to.

    a few questions for you guys..

    Years ago, I had some nerve damage to the nerve that 'activates' the muscle in my right lower leg that lifts the foot. Hence I don't have full power in that muscle like I do in the left leg. So I'll probably have better luck with the left foot being the 'under' foot. I think you're right about...
