Thank you, John!
Something I have found for the cut ends on heat resistant rope, is Gorilla tape.
Wrap, and heat, to melt, and it can flame some, then quench under cold water.
Have a great day!
Steve
That’s a good way to do it , definite improvement
Thanks once again John! Looking forward to trying this now that Turky season is over here in VT. I saw your new product video recently and may consider it if my walking stick DIY version proves impractical. Keep up the outstanding work and excellent demonstrations.
Appreciate the note and support. The new Maverick pole is working great.
First of all, an excellent video and excellent concept! While the concept of using two carabiners for progress capture (the method utilized by your Garda foot loop) has been used by alpinists for over a century, I am impressed by your addition of the “best friend” loop. Any climber who takes the time to add redundancy to their climbing system is an intelligent climber.
For anyone watching this video who is a beginner, I would strongly encourage you to pay close attention to this technique. Not necessarily this exact technique, but pay attention to how John has added a redundant connection point to his Garda foot loop. Should his primary climbing method fail for any reason, he would be caught by the “best friend.”
As a beginner tree climber or saddle hunter, I believe that you should always make your climbing systems redundant until you have become more experienced and confident. Using redundancies will build confidence because you will always know, in the back of your mind that, should shit hit the fan once, you will have a secondary to prevent you from experiencing catastrophic failure and keep you from plummeting to the ground, either injuriously or fatally.
Secondly, John, what are you doing with that heat shrink nonsense? Those cannot only make it difficult to pass the ends of your cordage through/out of devices and/or knots, but they may even slip right off during the process. Me, personally? I ***whip*** the ends of ALL of my cordage (whether it be my climbing ropes, my hitch cords, or my accessory cordage) using polyester twine, a sewing needle, and some pliers. I’m pretty confident in saying that every single piece of cordage I own has been whipped, taped, and glued.
Before whipping, before I initially cut the cordage, I wrap the cut points tightly with 3M electrical tape, then make the cuts using a box cutter with a fresh razor blade. I will then apply super glue to the ends and allow it to cure overnight, with the cordage hanging so that the ends are pointing directly upwards so it cures evenly. Then I will spend roughly 10-15 minutes sewing each whipping using 1mm, colored polyester thread (sometimes waxed, sometimes regular; the colors can help you organize and more easily identify your cordage/make your ends high visibility, etc.) about one half inch below where I’ve wrapped the tape. When whipping, be sure to not only make wraps, but to create perpendicular cross whippings to secure the core in place.
I made an entire video demonstrating this process, but I’m not going to link my content on another creator’s channel because that’s socially unacceptable. But all I can say is that a proper sewn whipping is world’s better than any shrink wrapped end. Especially if you’re working with hitch cordage, which is partially or wholly composed of aramid fibers, which will not melt.
A properly sewn whipping will never come undone, will never come off for any reason, regardless of how forcefully you pull them through a tight knot or anything else. They will make it easier to insert the ends of your cordage through devices and knots, help to spot any tails in a knot that might be dangerously feeding through, prevent the core from milking out, prevent the sheath from sliding off, and give everyone around you the impression that you are organized and thorough.
Finally, I see you’re using the Ceros carabiner by DMM. I recently bought one and I was immediately irritated when I discovered that the wire gate at the bottom doesn’t allow arborist sized anchor rings to fit inside of them, limiting me to connecting it directly to my bridge, which results in an orientation that I HATE. So, I used some pliers and removed the wire gate and now I love my Ceros and use it with my rope wrench all of the time. I got the triple action gate. Not sure if yours is triple or double action, but mine is a gun metal color with a green gate (the standard color or a DMM triple action gate). Even without the wire gate, due to the tight bevel at the bottom, and the “horn” along the spine, it is impossible to cross load. I wish it had the removable captive bar instead.
Great video, John! Sorry for writing a dissertation/essay in your comments section! Much love your way! We’re like two peas in the same tree climbing creativity pod! Keep creating, testing, and discovering new ways to advance the world of tree climbing and arboriculture! I’ll be over at my channel doing the same! =-D
"As a beginner tree climber or saddle hunter, I believe that you should always make your climbing systems redundant until you have become more experienced and confident."
Isn't this how experienced and confident people eventually get hurt? 😅
From what I understand, you always want two connections (main and back up) regardless of the amount of your experience or confidence.
Thx brother. All I can say is that adhesive HST works great. Saddle hunters want something fast, effective and scent free. The odor from Whipping Glue isn't acceptable. As for the Garda Hitch, please know that the traditional variants which just used a Girth Hitch or similar are not reliable. That's not just my opinion. I researched it and I tested them... it's pretty disconcerting when the Garda slips. My Bull Hitch variation used on the webbing addressed that problem. And the Clove shown here is used in conjunction with the Bull Hitch on the webbing.
@@Pygex As an experienced tree climber, I regularly will ascend using one climbing system with one singular anchor point; whether that be a canopy or basal anchor for SRS, or a cambium or pulley saver for MRS.
Once I reach where I need to be in the tree, I will immediately connect myself to a suitable TIP (tie in point) with my lanyard. At this point, there is redundancy. But as soon as I need to move up or down in the tree again, I take my lanyard off, and reposition on a single system with a single anchor point.
This is EXTREMELY commonplace in the world of arboriculture and is the norm for tree climbers and arborists. If you become an experienced tree climber, you WILL regularly climb without a redundancy until you make a stop somewhere, perhaps to make a cut with your chainsaw. Then the lanyard will go on right away first to provide redundancy.
Many professional tree climbers will often ascend the stem of a tree using just a pair of tree gaffs on their boots and a single flip line. No redundancy whatsoever until they get high enough to where there are branches that are suitable for installing a primary climbing system.
Skilled tree climbers REGULARLY climb without redundancy in their system or method. Maybe you're a saddle hunter and don't know much about arborist style tree climbing because what you're saying simply isn't accurate.
@@jrbtc Understood. As for the whipping glue, I have never used it for my whippings. I simply seal the ends with super glue, which, once it has dried, is completely odorless. Also, I really do like the Garda foot loop concept. It's very convenient and it's sometimes preferable over a toothed ascender. Especially since you can ascend the Garda by pulling on the strands, which provides a bit of mechanical advantage or, at the very least, it's quite ergonomic.
@@Knot-orious As an Arborist that still does Tree Work (Removal and Trimming at the age of 71) Your comments are a Joke!!
Straightforward and sensible evolution of the system. I like that it helps prevent carabiner contact. The only downsides are consuming more cordage, and harder to untie (e.g. for inspection).
I wonder if the hunter's bend could capture a strand of the overall loop to effectively become a "sliding hunter's bend"? That would theoretically be the best of both worlds. But it would require testing to ensure that the hunter's bend is still stable and strong in that configuration.
Sliding Double Fisherman's is easy to untie. Just slide one end thru. The standard double fisherman's is impossible to untie.
The one thing I have been wondering with the back up is if using static rope for it is dangerous or not? I switched my back up connection to one made out of dynamic lanyard (Petzl-I) because I don't have the equipment to measure drop tests on the back up.
For what I understand, the peak impact force is affected by:
- how much mass is on the rope
- how much the rope will stretch
- the relation of the length of fall (slack!) to the length of rope in the system
The latter would imply that even on a short fall you could get hurt without proper shock absorption. This is why we never have any slack on the main connection to the semi-static lifeline.
With the Garda, your back up is always below your main tie in point, so we are potentially looking at a factor 1 or greater fall depending on where the failure happens. It all of course depends on how your main device fails and if you can react to it with your feet (slipping versus catastrophic failure) but assuming the worst case scenario (a straight drop), what would be the peak impact force of the static "best friend" to a static bridge versus a short dynamic lanyard that is directly connected to your harness? Obviously the dynamic lanyard will be less but the question that is interesting is does it matter in terms of damaging a person?
I have researched this extensively and my conclusion is that if a catastrophic failure of our primary friction device occurs at the worst possible instant, it would be the moment after we have taken a step up but not yet advanced the Garda for the next step. Because once we advance the Garda, we are on zero slack. What would be the distance of that fall? Depending on the geometry of the system, it is probably about 12" or 30cm. I have tested how it feels to absorb that in a saddle. I will publish it in a future video. It's uncomfortable but not catastrophic. Also, it's very unlikely, given that a friction hitch is much more likely to slide rather than fail completely and suddenly.

@@jrbtc Based on the link above, there can be a minor chance of injury in a very unlikely event as we have discussed. Is there any difference in how comfortable it is if you were to use dynamic rope instead for a back up connection during an unlikely catastrophic failure? Any chance you could drop test it with weights and the load cell?
Obviously an unlikely injury is better than an unlikely death, which is why any back up is better than none, but I am very interested if there is any benefit to investing in and carrying a piece of dynamic rope for the back up over a static one? That is, does a dynamic piece of rope convert the very unlikely injury into a zero chance of injury or does it function all the same in this case to the more static one due to the shortness of the rope?
As an example, if you plan on going solo deep into the woods where even an injury can mean a lot of trouble, is it worth it to do the hustle with the dynamic lanyard as it costs more and is quite a bit more bulky than a piece of 8mm accessory cord? Does the added stretch make a significant difference to the likelihood of getting injured or not in the very unlikely event to justify the extra cost and hustle of the set up?
In terms of the Garda, you would need to first set up a cinching accessory cord as short as you can and then you would need to connect that with a locking carabiner (one with a wire or bar preventing cross load) to the dynamic lanyard which is then tied to your harness or extremely shortened bridge with a figure 8. The lanyard can stay there on the harness or the birdge at all times but the set up is quite a bit bulkier and messier than simply connecting a carabiner to the same cord that cinches the Garda and having that cord directly be of the correct length.
@Pygex I am not equipped nor planning to do formal drop testing. My plan is simply add a scale inside a static system (with me in the system) and simulate potential failure modes, measure the force and take it from there. I would agree that any dynamic cords or ropes we add inside the system will reduce impact force on the climber. That includes the rope itself and the bridge. All are potential areas of experimentation and measurement. I don't have enough information now to commit to a strategy.
Also, when doing FMEA analysis, the likelihood of occurrence is a very important input. In my opinion, the likelihood of a friction hitch sliding and not holding (for whatever reason) is a realistic possibility. But the likelihood of a Longhorn Agile hitch snapping somehow is fantastically low. There's two loops and they would both need to snap.
