In my class we call that a "Time hand Grenade." You may not get this now... but eventually you will. 11 years is a pretty good benchmark!

Thanks!

Thanks!

Glad it helped out!

Thanks. Glad it helped!

Glad to hear it helped out. Just as a heads up, should you accidentally unwrap your over-underfed cable in the wrong direction, you will actually put a knot in it every other wrap. You might have been wrapping it correctly with your other attempts and just got unlucky. While I don't have a video about it, you can stack all your knots in the same direction and run the cable through all of them at once to pull the knots through. It's an extra benefit of the method that I didn't add because the video was getting long. Hop that helps.

My Dad raised me on the elbow method. Makes me wonder what else he told me was wrong...

Yeah, it's the string that lets when you know you've gone too far.

VERY impressive. You should take that act on the road!

@@davidmckenna858 My act has been on the road for 47 years. Every gig ends wrapping cables.

@@alcraig1 Solid.

Hmmm, trying to think about the enemy attacks that these two motions would defend against...

Over long cable runs (20+ feet), you will get a kind of "pigtail" effect as you run the cable out using only overs. By alternating the wraps, it returns the cable to a relaxed state on the floor. This ultimately extends the life of the cable and makes for less of a tripping hazard. Hope that helps.

@@davidmckenna858 thank you for explaining, feels weird but I'll practice it

Visually it will look very similar with two distinct "unseen" differences. The first is that by alternating the wraps the braided shield on the inside stays straighter and increases the life of the cable. Striaghter is a relative term here in that with each warp you are veering in a particular direction just a little. So with over-under, it's like driving your car turning slightly one way and then turning slightly the other. Over-over would just keep turning in one direction which ultimately puts tension on the braided shield that can lead to fraying. The other difference is that -try as you might- there will always be the time when you accidentally unwrap the cable from the wrong end and you create a string of knots. With over-under, you get half as many knots to untie as over-over. There's actually a method of stacking the knots so it's not such a chore, I just did not have time to cover that as well in this video.

@@davidmckenna858 thank you.

Very welcome.

Glad it helped!

Technically you can do that in the other direction as well; however, when you create the coils by twisting you are adding torque to the cable that over time will fray the internal ground shield. That said, there is a way of not releasing with your dominant hand that I consider an "advanced" way of doing it (but it uses a lot of "yoga" and also a bit of "zen" so I don't show that here) And yes, I know that by me throwing the cable at the start of the video that I lose all credibility when I talk about issues of maintaining cable life.

Remember that when you started the coil, it began with the jack/plug facing you so the end of the coil has the jack/plug facing away. When you take the cable out of storage, begin by unwrapping your coil from the facing away end. That should prevent the problem most times. However it's still possible that the jack/plug managed to get itself through all the loops and create a long series of knots. In which case, you can actually stack all the knots on top of each other (have them all facing the same way) and then run the jack/plug through the middle of your stack of knots to untie them all at the same time. I thought about covering that info in the video but I figured it was already getting a bit long. Hope that helps.

@@davidmckenna858 Thanks! Mucho! But don't be afraid to add that part to the video.

Thanks for the kudos. In fairness, I never promoted the video as it was made for my students at UCLA. Given the I only have about 100 students a year in my audio program, that makes about 43,300 more views than expected.

GAH! I know your pain.

What's the technique for properly elbow coiling? If you don't have some equivalent for countering the twist like over-under you will necessarily (there's a whole branch of math around this) either leave the cable twisted under stress while coiled or cause twists/knots when uncoiling (or some of both).

No. NEVER elbow loop!

This video is easier to follow if you're lefty. The instructions are identical except you get to mirror his movements instead of having to flip it around in your head. There's nothing directional about his instructions.

It's literally easier to copy as a lefty. The verbal instructions are identical. You just have to mirror what he does instead of having to flip yourself around.

Glad I could help.

Cables Wow so 40 years ago get you some airpods

I may or may not have done that a few times in my youth. But definitely not recently. I might hit the drums.

As a side note to this post, technically any time you make a loop in an audio or video cable you create an antenna that will introduce noise into your signal. So unless you are in a well-shielded studio, you will want to completely uncoil your cables when in use. This of course begets the question, "But what about any leftover slack?" Answer: Always use the shortest cable possible to minimize the excess. Then hopefully you do not need to make so many loops.

@@davidmckenna858 Good to know. I did not know this.

If you're desperate, you can double the cable back on itself, rather than coiling it, so the EM fields cancel out rather than amplify, using the tightest bend that's healthy for the cable. The longer cable will still add resistance, reducing your signal, but at least keeping the noise relatively similar. As David mentions, coiling will make it an antenna, amplifying any RF noise received or transmitted. But the cable won't heat up meaningfully more when coiled (and if your cable is heating up you're running WAAAAAY too much power). And the cable would melt far before it had enough power for the EM field to be even vaguely dangerous.

The issue with the knots can be frustrating; however, if you stack all the knots facing the same way and then run the cable end through all of them at once you can clear this problem in 20 seconds. I thought about doing a separate video for that very process because, as you pointed out, this video was already a bit long to include that information here. Sorry you felt my description was too complicated and took too long. I genuinely made this video for my audio students at UCLA expecting 50 views a year. The internet had other plans.

Glad to hear it! I actually thought about using the "touch wrists" verbiage but decided to keep things related to the thumbs for consistency. I also had to resist the urge to describe the arm rotation maneuver in the under loop as feeling like a disco dance move.

David McKenna yeah you did it perfectly. As they do it they’ll figure it out for themselves anyway lol. And lmao!! The accuracy! Indeed it does. Especially when breaking things down and wrapping cords in a hurry after a gig. And they say disco is dead 😂

You are very welcome! Always wanted to go to Chile as apparently it has the closest climate to California in the world (and I love the California weather). All the Best my weather brother!

@@davidmckenna858 I'm from Chile too! You need to come to the 4th region (Coquimbo's region) and see the beatiful valleys. Btw thank for the video!

@@Jonathan-jm8ns Chile is rapidly moving up my list of places I want to go! Thanks for the recommendation.

I've always done the same. I learned how to coil high pressure hoses years ago, which are also finicky and critical, but I've never used the over/under method. All my cables I just wrap like it came when I bought it, and they still look like that years later. I've never tried throwing one across a room to see if it unravels without knotting, but I suspect they would. With high pressure hoses, each col got one twist. IF you got the twist wrong, you would know it because the coil shape would get screwed up, and 300' of high pressure hose, forcing it into shape without the twist is not even a possibility like you could with a garden hose. I've been doing the same with my cables and had no problems. My coils are perfect like new. I've also worked on loads of productions, been asked to "wrap cables" and when inspected, my wrapping has always passed without a problem. On one occasion I was asked if I used the over/under method, which is what prompted me watching this video, but that was the end of it. There was no complaint or re-wrapping of that cable. I'm going to have to do some experimentation to see if the end result is the same. Is the over/under method the ONLY correct way to wrap a cable? Why am I not experiencing any problems? My extension cords re even perfect. I can't not wrap a cable like a hose, so learning this technique is not intuitive for me.

That's interesting. We use over-under for all our stingers here at UCLA Film. If your production house wants it over-over I guess that's their call. Where over-under works really well on production is that you can set the stinger coil on the ground and just walk it to whatever gear needs it without getting any "pig-tail" effect over that distance. The only place I recall seeing over-over is for the TV Camera cable for short cable runs on the studio floor. Once it got to long camera cable runs we switched to figure-8s.

@@davidmckenna858 Thanks for your response, actually I have always done over-under..[I teach it that way]..I saw over-over for the first time on a UA-cam, someone brought it to my attention...took me back....I never had anyone say otherwise...ua-cam.com/video/oymnMuXe9f4/v-deo.html My response was...that's interesting.

Glad to help! I remember I had to do the movement in slow motion and really break apart the components to be able to explain it in this way.

While I did not mention it in this video, I am a HUGE fan of Ball Bungees for cable management. Nothing is faster and easier for when you have to make quick adjustments to your recording rig in the field. Making a hanger specifically for your Ball Bungees is nothing short of brilliant. I wish I had a cable wrangler 25 years ago!

I too am dyslexic! Maybe that's why I thought to teach it in the way I did. It genuinely makes my day that I could help.

@@davidmckenna858 Same for me. The other videos were of no help at all. Thanks for the instruction.

@@effigies7896 Thanks for the kind words. Glad I could help!

While not one of the focal points of this video, by alternating over/under you get a net 0 torsion on the cable. This means you could set the cable down, grab an end and walk to the device you want to plug in without the cable wanting/needing to rotate in your hand lest it start to curly-q like a pig's tail. As far as "remembering" where you are, after enough practice it eventually becomes second hand such that you never get lost. Even if you do, you can look at where the cable is resting (inside or outside the loop) and just perform the opposite. Whenever I can't easily tell due to a REALLY long cable, I just unwrap one or two winds until it becomes obvious.

Thanks for the info. This is one of the most useful things I've learned in a long time! I wonder why they don't put these kind of instructions on the cable packaging. I re-tried doing "over-under" on a 25', 14 gauge extension cord. I threw it 10', and it had some tangling. If I do "under-under", and throw it 10', it's curly, but no tangling. I can then pick it up, and reduce the curliness. The width of it when wound up "under-under" also seems less. This way of winding it makes it like a spring. Do you think there could be any reason to do one or the other, based on the wire gauge? It seems like another way of saying what's going on with "over-under", is that it's accounting for how there needs to be a slight twist in the wire, to keep it from kinking up. It seems like to teach "over-under": do the whole wire "over-over" . . . then "under-under" . . . see the difference . . . then do "over-under" What I'm thinking is: Over-Over is standard for most people, and tangles . . . Over-Under is good for thinner cables . . . Under-Under is good for thicker cables, like 14 gauge

Wait, I see how the twist works, better, in this vid: How to coil cable - UA-cam . . . This method works for garden hoses, too! . . . The twists cancel each other out, resulting in no net twist . . . ua-cam.com/video/-qO36-CfZKg/v-deo.html She holds the end away, and you see the wire as a circle, not head on . . . Also shown is how "over-over" gives you a tangled wire I also now see from my own try, how "under-under" gives you a curly pig-tail wire.

@@slack7638 In retrospect I regret throwing the cable in this video. For one, it can easily damage connectors on the cable. For two, it does require some practice to not get tangles. It is best to just set the cable on the ground and walk out the desired length so that it remains partially coiled and less obtrusive in the work environment. Again, the curling you are noticing is undesirable torsion that can decrease the overall lifespan of the cable. Regarding cable gauge, thicker cables like 6 core tend to be wrapped using a large figure of 8. As this video was intended for my film and audio students here at UCLA using thinner cables, there was no point in mentioning that.

Torsion, how do you explain that - makes me think of this video, where they can simulate all kinds of sea "waves": The Navy's Indoor Ocean - UA-cam . . . ua-cam.com/video/YKx1Rbqpaog/v-deo.html I'm just thinking, for me to learn, it helps to see the big picture first - all the possibilities - and then just focus in on what you want, or the right way to do something.

As someone who used crochet when I was a young live-gigging engineer, I've found that crochet puts a LOT of tension on an audio cable and can significantly reduce its life. One argument for crochet is when you only have one really long AC extension cable but only want to use a small portion of it while keeping large sections of it still looped. At that point, you are trading off incremental cable life for the time of not having to re-wrap100' of cable every time. Of course, the real solution is to have cables of multiple lengths so you have the right one for the job. I have 6'/10'/15'/25'/30'/50' cables that are all color-coded. A bit overkill, but when you are dealing with cables all day long it saves time. Another reason people may gravitate towards crochet is the fact that the cable is "contained" and cannot get tangled with itself or others. To that argument, I just say that I have velcro ties on all my cables to achieve the same end AND I get the added benefit of velcroing the cable to the mic stand to ensure a mic absolutely never hits the floor unless it takes the whole stand with it. Hope that helps.
