Singing Tree Rope Wrench

Been here much more than a while
Location
Detroit, Mi.
In 2008 I traveled south to Texas and did hurricane work clearing hangers and leaners along trails and back roads of Texas. During that time, I adopted SRT as my preffered climbing style and came up with the Fate Revolver out of necessity. I was forced by circumstance to climb SRT and adapt to the equipment I had on hand. Isolating limbs was a huge time eater up, i had to move fast as I was getting paid 6 dollars a tree :( . I was heavily using a ladder for access as well and so I began only climbing with my hitch on single line. The Fate revolver soon followed.

I posted the fate revolver on treebuzz two years ago.

This system of climbing became my preferred method of climbing as many of you know from my constant chatter about it.
There has been several important contributions to the system such as the Kong Robot by Hollenreich and FamilyTree, and The pulley and ring setup that Rich Hattier found. Tree Machine introduced me to the Conterra Scarab which I was using until recently.

Several tree buzzers now use this system of climbing some of the time when its practical, others like me use it virtually all of the time. Those who use it or have tried it, know that there are several big downsides to the system. mainly that you cannot ascend directly up the rope with the device attached. Nor can you descend easily with the system not attached. This can cause annoyances that can dampen the thrill of SRT climbing. I still found the system to be overall more efficient and practical than traditional dDRT by a long shot.

Two weeks ago on september 30th, after a particularly frustrating day in the tree I decided that I would no longer attach or detach myself from the friction device above my Hitch. What you see in the picture is one of several rope wrenches that I have utilized in the tree for the past two weeks. It is the Singing Tree Rope Wrench. It is a portable limb that gives the required friction to safely descend the rope. This one is made from one piece of Hickory. It is threaded at the bottom of the rope and rides above the hitch for the duration of the climb. During ascent it is simply pushed up the rope by the hitch below. On descent, it engages and imitates the rope passing over a limb as in ddrt, or the fate system. I like wood as a the medium as it is friendly on the rope but I will be experimenting with aluminum, stainless steel, plastic and possibly titanium. I have a feeling that this is a device with a lot of variables, like what rope is used, what hitch is being used as well as the weight and personal preference of the climber. I am excited by the fact that any crafty climbers can fabricate their own rope wrench out of a special piece of wood or the handle of a hammer. I have also made an accompanying hitch tender out of wood to eliminate even more metal from the system. This is a tool that kind of takes us back old school while still advancing us forward.

Currently I am only making them in wood for those of you that are interested. Like I said I hope to be making them with other materials soon. I will consider it an evolving experiment but this tool in its current form, does work and is fun and efficient to climb with.

I'll vouch for this new system Kevin has shown. I got to see it in action first hand the KYTCC and it works like a charm. I may actually try to start climbing SRT soon, because this system works so smoothly. It removes many of the down sides the other hardware caused(jamming at the hitch during slack tending, etc) and it works extremely smoothly. As soon as I get some extra cash I plan on ordering one.
 
Much like Kevin I am currently climbing only SRT to do my work in trees. All the advantages of climbing SRT well out weight the disadvantages for me and i find it the most efficient way to climb. I too have been trying to develop something that accomplishes the same goal that Kevin was able to do with the Rope Wrench (our ideas were scary close to each other) and now i feel it makes SRT with a hitch even more efficient and practical for any climber.

I got to talk with Kevin extensively about the rope wrench, even got to give it a ride.

I'll admit when first seeing that it was made out of wood i was skeptical. The more i talked to Kevin about it and as i continue to think about it wood is a great material for it to be made out of. How many of us have used a natural crotch when climbing? Probably everyone of us, we can agree that the interaction between wood and our rope is nothing new to anyone. The beauty is in the simplicity and the effectiveness is something you truly have to see and experience to fully grasp.

If your concerned at all about the strength, understand that this is not bearing your weight simply reducing the amount of friction that is experienced at your hitch. Your hitch has you backed up at all times! As long as you can trust your hitch you can trust the system.

Congrats Kevin with the simplicity and genius of this "tool" (see how i did that) Look forward to the continuous progression of SRT!

Are you making them for sale?

I haven't seen the whole deal, as some have seen it in action, but I think that I might already be a convert.

I'm in.
 
Something to consider as far as using wood goes

ART already utilizes a very strong Brazilian wooden handle in their spiderjack design. Might be worth checking out.

The inability to descend on command is what has been keeping the F8 system out of my daily climbing technique. I often use my unicender because of it's quick ascent and descent capabilities. I've been climbing with the F8 system a lot more often the past few weeks because I am currently training a climber and he is strictly SRT which means my UNI is not an option for me. I hate switching back and forth for ascent descent modes. This is a great fix and hope it becomes available soon

If you're looking for any guinea pigs, I'd be more than happy to help and write up a report or two
 
you are brilliant my friend.
I hope you have one for me t purchase at Geezers.
Stay safe!

Splitting with the grain is wood's weakness (duh, I know you know). Wrapping with tape would prevent splitting but ruin the aestetic. Or I suppose look to engineered wood like glue lamination.

Wood as a friction surface could be excellent. I bet the old sailors used something like ironwood for running ropes.

what's this?

Instead of using the figure 8 and the DMM Revolver he used a pulley and a ring (not sure of the size)

the pulley resembled this:
http://www.heightec.com/equipment/pulleys/pulley-alloy-2-cm.html

and the ring (now again don't remember the size) but you would take a bite of rope slip it through the ring and around the pulley and then your anchor end (i believe you can call it) would clip into that pulley
 
Kevin if you don't mind sharing. Did you drill a straight hole throw the wood or is it angled and how is your hitch attached it? Am I right saying the same way a F8 syst. Would be attached? My dad is a custom cabinet maker/ wood worker and I think he might have some great ideas for your tool ex. What wood to use diffrent cuts..... do you mind me asking him? I don't want to step on your feet here. Thanks Sam
 
I do believe that one of the thrills of this tool is that people can make them themselves. I would not want to deny people that. Of course, I don't want someone making them and selling them. I have sent in a patent pending application (provisional application). i really don't know what thats worth though. it gives me a place in line and a year to file a full patent. The lawyer said that this gives me some protection and i can show it to people. I have had a hell of a time keeping my mouth shut for the past few weeks while working on this. i expect the models will improve slightly as time goes on. in my opinion, The model i am currently making is the smoothest way to climb a tree SRT with a hitch.
 
So, the hole is angled and carved to cause the rope to form an S shape when under load without causing too sharp a rope angle. I have been attaching the tether (8ml beeline) with a little clevis to a hole in my hitch climber. I am currently working out the bugs in my frog walking system and will be making a video shortly.

Its funny because my first models of this were much more complicated. I believe that making it with an opening side cheek is very possible but it would add expense and one of the nice things about it is that it should not be very expensive.
 
I few years ago I brought four hickory logs home and had them milled.

here is a video of me bringing the log home.

the wood is now dry and ready to use. I have seen no evidence of it wanting to crack. I will be taking a few to John Hartenburg to have them break tested and will post the results.

Tomorrow my plan is to make my tether with lite string and cut it while descending with a pair of scissors to simulate complete failure of device. (stopper knots will be tied in rope under me.) Based off of my experience thus far with hitches on SRT, the rope wrench is not a life support tool and should not be used without rated cord in good condition.
