How to coil a rope to prevent twisting and hence snags and tangling when you toss the rope down an abseil.
"How to coil a rope to strangle yourself"
Dave "Indiana" Jones...
I hope you appreciate how many people are now standing in their room looking silly, getting themselves tangled in a bunch of enthernet cord. Including myself. Maybe. Probably. Likely.
Okay what function do I put my multimeter on to make sure I've done it right?
Just check your ground points with the buzzer, if you don't have a solid ground it won't matter how you coil your rope ;)
Inductance, duh...
It's a coil
@Aifryz please show me a decent multimeter that I can also measure Henry's in please.
You use your oscilloscope, the rope shape made a polar equation.
So you've shown us the ropes with no strings attached.
:D dad joke of the day!
Instant Bob Marley hair :-)
Kind of related... for garden hose on the ground, lay it out in a figure '8'. Yes it requires more real estate, but pulls out free & clear (unless the end is allowed to pass through one of the end loops). All bets are off for cheap stiff plastic hose; especially in cold weather.
For those cheap hoses that kink easily, assuming you've laid them out properly, pressurize them before uncoiling. The pressure stiffens them up a bit, making them less likely to end up with those sharp bends and twists that end up in kinks when you pull on the hose.
For garden hose use over Under method for cables
Used to do this with climbing rope at the top of a climb. I could coil 50m of rope in a few minutes...
It also looks really slick when you throw it down the crag and everything neatly unwinds.
Except the one time I forgot to hold onto the other end...
Finally a way to coll my USB cable without tangle it up! 🤪 thx for this rope trick!
Same for microphone/other electrical cable, to prevent internal twisting of wires... useful! (:
@Vynncent Murphy Just search for it on YouTube. You might have to look at a few videos before you understand it. It's not difficult once you get the hang of it, but it looks like slight of hand unless you see several examples of it. You might hear them mention "thumb up, and thumb down," and that makes it easy until you get it down to a reflex.
This is NOT how to coil microphone or DMX cable.
But how? Definitely not around the arm, 'cause that would twist wires inside. I personally pick the middle and stack them over from there...
@Liviu-Dan Timar It's most obvious with a garden hose - if you roll it up and then unroll it, there's no twist. This is how fire-hoses are handled. But if the hose is wound along the axis into a loop, then there is a net single twist that is applied to the hose for each turn around the loop. When making the loop in the first place this isn't so noticeable as the free end of the hose will just turn. However, when reversing the action, the bulk of the loop is not free to turn and so as the hose is pulled back off the twists add up.
The over-under/right-left/et al, depend on flipping alternate loops as they are added so that each twist is balanced by a twist in the other direction so that the overall twists add to zero. If it were a screw thread, one would be right hand helix as it is laid on the previous loops, and the next is left hand helix.
I use the daisy loop or chain stitch as they call it for various cables.
Awesome ...thanks this is perfect for "someone" i know lol .....cheers
Nice - I can do that with my knickers, too!
Sweet. I'm going to use this next time I use my sewer line cleaner cable!
Ah, it reminds me of the time some one showed me how to use a wheel barrow properly :D It's surprising how many of these neat little tricks go under the radar.
Have you patented this amazing technology?
I guessed a long time ago that you had rocks in your head. 😃
Good to know, Dave! Cheers.
Thanks! That could also work with electrical wires too !
sounds like your have the echo switched on on that Yamaha amp
Hahah.. Dave you never fail to put a smile on my face !!!! Hope you an all the family are all good. :)
It's official... Dave has lost it :)
Hi Dave!
The second wiring around you neck I know about as offshore guy, that winding can also be done with the hands.
I often use this also for electrical long cables.
Happy absailing!
As a hangman, I found your tip most useful.
try to do this with straight arms, it works better..
I don't know where you get the energy lol
Could save someone's life
extension AC Power cords... interesting, i have a different method with 1 arm elbow..
Nice reverb filter on the audio, which one was it?
An electrician taught me a similar method for extension cords. your way looks faster.
TIL Dave is work for NSA.

I have always found the “Figure-8” style of rope/cable winding to be effective...
Hey if it’s good enough for Live TV camera operators, it’s good enough for me. 👍
Very informative ,Thank you 👍👍👍👍
“Butterfly coil with farmers tie-off” Sapper style
And no loopy round the ankle.
There's another method in which you coil one loop and invert the following one, kinda hard to explain, but it works for anything, not only giant ropes. Once you get the hang of it you'll do it on anything without even thinking, I even do it on small USB cables, it really helps. Edit: it's called the Over-Under Wrap method, check it out.
There's a mnemonic device for that, "overworked and underpaid" =)) Big Clive had a video about it a while ago.
That's the one you can do in your hands. Much better for wet rope, nobody wants 50m of wet rope slapping in their face.
Am also a fan of the Over Under method.
This is great for Ham radio antennas!! - ZL2BCI
30-metre waterfall, huh? Sounds empressive. 😉
Nice tip. Thanks.
Would work for power leads as well
have coiled a few large powerlines cables that way, a bit heavy at the end on the shoulders but you can at least do it alone.
Great tip
Next: how to tie a noose
Absail !
None of this repelling rubbish !
Over under method is the best way once you master it.
next video, show us how to tie shoes...
now its time for some bush tucker & throw them snags on the BBQ
Make a canyoning video!
Crocodile Dundee right here ^____^

I guess that's to avoid inductance on the rope
