- Caleb demonstrates the simple technique for moving large objects with just a rope and two poles. This method is commonly referred to as the "Kochanski Flip-Flop winch". A very handy skill to have in bushcraft or survival training.
Thank you Caleb, very useful lesson
Nothing against Mr.Kochanski but that is a spanish windlass.We used to use this way back when I was a kid to tighten barb wire.This system is very old.btw that is a timber hitch you used to fasten to the stump.The system was nicely explained tks

The Spanish Windlass is actually slightly different. Mors wrote a whole booklet on the subject of the Spanish Windlass and the Flip-flop winch.
Thanks for showing us the technique. That could be very useful.
Very good ,heard of the technique but never seen it done ,thank you sir you got me subscribed...
Excellent! I'm gonna try it this weekend!
Super job !!! have never seen this done,Thanks for sharing.
As mentioned in other comments, we had an assistant to speed up the process. Heavy stout poles make this definitely a 1 person job. Three winters ago we actually demonstrated this winch to our students by loading a 250lb ATV (in neutral of course) loaded with 200lbs of kit on a 50-degree incline. A single student with a strong mountaineering rope and two heavy ash poles did the job on their own. Others have done this trick even with a jeep stuck in the mud!
Work, energy, elasticity: As a practical matter a static line is most time efficient, as you don't waste it storing energy in the stretching line (with the added risk of much more movement in the case of winch line failure). Also, a single layer wrap of line is preferred to a stacking which eventually collapses, wasting recent effort.
I see two options for this special modified use for the principle of the ancient "Spanish Windlass". First option, where the lines wrap the toggle log, on opposite sides of the pulling log, which puts a consistent tension on the long end of the toggle (preferably away from the anchor, to simplify its control with a simple "control" line from the anchor to the long end of the toggle.
The second option, where the ropes wrap around the toggle log, on same side of the pulling log, which puts much less torsion on the toggle, but makes the system clumsier to use because the ropes (even closely wrapped) spread along the length of the toggle, farther from the crossing (than if they were on opposite sides of the pulling log).
A more recent video than this one (ruclips.net/video/QFDGGht3CQU/видео.html), which has more than 4M views) has my '230824 comment with a more explicit description of this setup and several variations that are worth understanding.
Great technique, thanks for sharing.
Caleb brother that is a genuine technique. Thank you for sharing it with us.

That is often the case with the Spanish Windlass. However the Flip-Flop winch is braced by the ground, and won't pop back up when tensioning. The trick is jst keeping the cords even. That is the only place where more than two hands are truly helpful
THANK YOU. I LEARN''T A GREAT DEAL FROM THIS VIDEO. APPRECIATED.
that is a great technology, thank you.
outstanding. thanks so much for sharing.
In the video I have from Mors he suggested putting in a couple stakes with rope loops tied to them, so that one could use the staked down loop to hold the log that is otherwise held by your assistant there. Unfortunately I can't seem to find the DVD or I would be watching that. Thanks though, for the video, I didn't remember how the weave was supposed to go, the stake trick came back to me as I watched.
great info, thanks for sharing!! :-)
amazing , great job
wonderful knowlege, thank you man.
Brilliant.
Anyone who references the great Mors Kochanski is fine by me. Subbed, baby!
Mors might use it but didn't invent it ! I learned this in the Boy Scouts over 65 years ago !
Nice! Great stuff!

Thank you!!
Thank you!!!
very nice maneuver,I have never seen it in any book or other video
Actually no, though a small loop of parachute cord hung off of the winching line and used to pin one of the poles in place would help keep the tension in place, the tension in this situation was not very strong. We simply wanted to speed up the process and so asked one of our dear friends Zander to help pass me back the poles. Half the labour means twice the fun!
You can also get more length out of your chains, or ropes with adding poles, sapplings.
thanks
very useful
thats a new one, thx
very nice demo, normally if you do it alone you need some thicker 2 heavier lever logs, so they don't pop back at you when tensioning...
Niiiiice trick!
Just one thing. Watched a similar video and the fella wound up both lines on the long end of the perpendicular log side by side . It eliminated the twisting you were fighting to keep it all straight .
As Mors himself taught us with the spooling happening on both sides, this is how we taught it. We have seen the other method since then and have indeed modified our technique.
Could you link that video?
There is always that possibility, though pulleys would be needed. At least two.
Is it possible to modify this to lift something vertically? Say, an engine out of a truck.
awesome idea, however the volume is like the idea.. flip flop, blare, then nothing then blare lol.
It seemed like u needed help in the end to hold tention , am I right ?
To pull what in general?
stuck vehicle
Mr. Kochański Hi is Polish.
Spooling should be only on the longer side, not on both sides. You almost had it correctly.
As Mors himself taught us with the spooling happening on both sides, this is how we taught it. We have seen the other method since then and have indeed modified our technique.
Haaaaaa! Good show my bushcraft brothers. Now I know how I'm going to move my neighbors house away from mine!!!
At 5:19 the stump is shown being pulled out. But good try on being a B.S-meter. ;)
it looked like you needed 2 people to do this
It took 2 people so I'm apparently missing the point of this being a 1 man job if your in an emergency that was a dead log i could easily move mysrlf but you say it could get out a stuck vehicle hence 2 ppl to move a dead stump hiw many for a vehicle?? Total fail in my POV
Just one comment; "dynamic" rope for rock and mountain climbing is not great for moving heavy objects because it has over 15% stretch; the purpose of this kind of rope is to absorb energy, and the break the climber's fall without breaking his or her back. This makes it terrible for pulling or towing things because it is bouncy.
Winching with it would be very frustrating as you would be putting a lot of energy into the rope before beginning to transfer the energy into the object you need to move.
There are methods to reduce the amount of stretch by tripling the strands, but that creates a lot of friction.
Though the dynamic of it can be used to advantage when trying to "snap" an object loose. in vehicle recovery we often use dynamic recovery straps to multiply the kenetic forces when you "snap" the recovery line taught. However that would not work well in the application as shown here. As a matter of fact the way it is being shown here I can see a huge safety problem as you've now ended up with a spring loaded flipflop. that can flip flop around and come into contact with you as the rope trys to release it's stored spring energy. Short answer is don't try this at home with dynamic rope.
A stretched rope will still be applying force to both of the objects fixed at each of its ends, so you're incorrect to say "you would be putting a lot of energy into the rope before beginning to transfer the energy into the object you need to move."
Imagine that you cut a rubber band so you have a nice stretchy string, and now tie a paperclip to each end of the rubber string. put this on a table and pull the paperclips away from each other so the rubber is stretched..and then let go. The paper clips will obviously move.
Hope that thought experiment helps.
I'm afraid the thought experiment is incorrect.
The rope absorbs energy by stretching, some of the force you're putting into the rope never reaches the object the rope is attached to. The fact that the "rubber band" gives the energy back backs this up - the energy stored in the rubber band had to come from somewhere.
When I fall on a climbing rope, the rope begins to absorb energy from the fall; at first I feel very little force as the rope begins to stretch, then I feel more and more - the rope absorbs the force of the fall until it reaches it's elastic limit. This is how I can fall without breaking my back.
The rope then slowly, over the course of the next 15 to 20 minutes, releases the energy in the form of heat, and contracts to it's previous length.
Another way to think of it is this; some of force you're exerting goes into lengthening the rope. Conservation of energy states that this is now not available to be put into the object you're moving.
It you're interested in a third party, this is a good primer on the physics of climbing (here caving) ropes.
www.karst.org/pgrotto/physicsforcavers.htm
Yes but the energy stored by the band is being exerted as force on the objects that it is fixed to.
If you put my thought experiment on the table and then began to pull on one paperclip...the other would move. The stretchy rope might "store" energy, but it doesn't "waste" it. The stretched rope simply builds up stored energy until it has enough energy that it can convert that energy back into work by overcoming resistance.
SOME of the energy may never reach the object, but you are still incorrect to say "you would be putting a lot of energy into the rope before beginning to transfer the energy into the object"
That is like saying "you would be putting a lot of energy into the rubber string before the paperclip realised the rubber string was pulling on it.
FLOP FLOP. Why didn't we see the stump getting pulled out? i call bs
Nope. Sorry. Give me the money shot of that cordage not breaking as the stump is removed. Otherwise I cry "theory great, practice flawed".
No cut. No stand in. No stunts. No camera work other than time lapse photography would be fine. Even failure would be beneficial to people who want to do this.
Sorry, but scientifically I cannot give you a thumbs up yet.
