Talk:2810: How to Coil a Cable

I don't actually know what name of 'coiling' it has, but the way I was taught to coil an AV cable (by an AV technician), and these days mostly use with long (garden-mower) power extensions, was maybe the 'quarter-turn' - though it's not a quarter, so maybe not - in finger-rotating the latest "end of loop" around the axis of the cable to leave it effectively twistless in its looped form (whilst introducing a 'one twist per loop-so-far' longitudinal twist in the still trailing unlooped cable that easily 'rolls-out' as you progress towards the free end/drag the length towards you). Done right, it's like smoothly 'drum-winding' the cable. But you can over-/under-twist the cable (especially if it has an internal/inherent twisting, like those christmas lights probably have with probably two entwined single-cores) so you may need to keep an eye on the multiloop you're forming and backtrack a bit if it looks like it's starting to figure-of-eight from the combined helical forces. But tricky to get perfect, may have a bit of a loop-twist (that only stays untangled due to it being ultimately hung on a hook). Maybe I've just not been taught the right methods by a powercord expert. 172.70.90.20 19:39, 2 August 2023 (UTC)

That first method is pretty much how I was taught by a guy with rather expensive microphone cables. It really does help the cable to last longer, since it's not stored with a twist. As a bonus, coiling a rope or extension cord this way also lets you throw it without it tangling in midair. Just make sure to hold onto/step on the non-thrown end... 108.162.237.142 20:12, 2 August 2023 (UTC)

I don't think they're meant to be Christmas lights. The lumpy bits that look a bit like lights are, I think, meant to be knots in the cable. 172.70.210.148 15:45, 3 August 2023 (UTC)

Another profession that deals with hose/cable managment is nursing (e.g. in operating room). Don't know if they have any techniques distinct from those in the mentioned professions. 172.69.135.82 21:50, 2 August 2023 (UTC)

Still wondering how topology factors into this... as of this comment, there's no explanation. - 172.70.130.234 22:38, 2 August 2023 (UTC)

Probably referencing Knot Theory. 141.101.76.97 23:17, 2 August 2023 (UTC)

I think the relevant mathematical concepts are curvature and torsion, which belong to differential geometry, not topology. 172.69.59.24 19:28, 8 August 2023 (UTC)

As a sailor once explained to me, the AV method (over/under) can potentially form a clove hitch around one's ankle while on deck, hence their use of figure-8. Meanwhile, there's another technique espoused by the likes of 'Essential Craftsman' where you basically use a chain stitch to hold it all together. Nayhem (talk) 00:35, 3 August 2023 (UTC)

I have a flat extension cord that was stored for some years using the "chain stitch" method. I ended up hanging the center of the cord from my garage ceiling for a week to get the worst of the kinks out, then wound it around a 5-gallon bucket to try to flatten it out some more. For the sake of your cables, DON'T use the chain stitch method!

This sentence makes absolutely no sense to me:

... alternating each obvious helix loop with a backhand loop (backwards helix turn) where the loop curls the same way as the other loops, but its 'helix height' is backwards ...

I think I need an "Explain Explain xkcd"... 😕 IMSoP (talk) 10:03, 3 August 2023 (UTC)

The idea of enlisting the help of an "expert" reminds me of how my father would always have the best charcoal barbecue at the picnic site. He would bring the charcoal and lighter to the picnic area and then walk around to see what everyone else's barbecue looked like. When he identified the best burning site, he would would walk over to the barbecue master and say to that person something like, "Excuse me, I really admire how your fire is burning, my kids are over there and I'm a little embarrassed that I don't really know how to do this. Could you show me how you got such a great fire?" The expert was always willing to build the fire for him. That's how, time after time, we always had a great burning barbecue. -- [[User:{{{1}}}|{{{1}}}]] ([[User talk:{{{1}}}|talk]]) (please sign your comments with ~~~~)

My reading of the comic was different to what's currently in the explanation. I read it as Cueball has just uncoiled the cable ready for use, and is annoyed at all the kinks and tangles that have resulted from it having been coiled up. The others are then so keen to demonstrate how to do it better, that they end up coiling it all back up again, which doesn't actually help him in the slightest. Which seems funnier to me. 172.70.211.190 15:34, 3 August 2023 (UTC)

My reading of the comic is also different... With (or in spite of) all this dubious help, he just bought a shiny new cable in step 4! Mathmannix (talk) 11:22, 4 August 2023 (UTC)

There is some controversy over "flake" vs "fake", see https://tradewindssailing.com/wordpress/?p=1343 for example. I learned "fake," the comic uses "flake." IDK.

White Hat presents the well-coiled cable

“Neatly coiled!” doesn’t look like a speech bubble, but more like an annotation bubble—it uses an arrow instead of a simple line. Thus it is not a “White Hat presents”, but the final step in this tutorial.--162.158.111.19 08:40, 4 August 2023 (UTC)

White Hat is still presenting it, even if he's not saying anything while doing so. And the transcript doesn't present it as speech by White Hat.172.71.242.191 11:10, 4 August 2023 (UTC)

Missed the joke

I feel like people missed the joke on this, which is the proper way to coil a cable is to say you need to buy a new cable due to kinks, and you will have multiple people tell you how you are coiling your cable wrong, while coiling it for you. Thus cable coiled. 172.71.223.77

As an A/V technician, often in 'amateur'/volunteer environments, this seems to be somewhat of a rite of passage. Commonly, either 1) a new teammember will wrap a cable in such a way I would find improper to leave like that for the next person to find, or 2) a visitor is willing to help teardown. Either case results in 'the conversation' where the technician gives some instruction and guidance. Aronb (talk) 20:26, 9 August 2023 (UTC)
