| Nov 11, 2022 at 14:31 | comment | added | Lundin | @BartvanHeukelom Yes, no, maybe... I'm pretty sceptical against crimp wire ferrules in the context of low voltage/low current signals. | |
| Nov 11, 2022 at 14:24 | comment | added | Bart van Heukelom | @Lundin it was my understanding that a good crimp squeezes the strands together so tightly that no oxygen can reach the contacts, and may even cold weld them together. It's just something I read once though, don't know if that result is so easily achieved. It depends on proper technique and tools, that's for sure. | |
| Nov 9, 2022 at 7:58 | comment | added | Lundin | @BartvanHeukelom I don't see how that would help against oxidation. It might serve as strain relief at some extent though. | |
| Nov 9, 2022 at 1:55 | comment | added | Bart van Heukelom | @Lundin do you think that could be fixed by crimping a ferrule on it? One that is very short, so as not to affect the bend radius too much. | |

| Nov 6, 2022 at 1:27 | comment | added | DKNguyen | @jsotola Do you know of a nice way to twist "inline" cables? I have always thought of doing the double spiral thing that a blood knot has but it's always been too much work, especially if it was stranded wire. I suppose you could just overlap the cables end to end facing in opposite directions and twist them that way rather. Why have I never done that? | |
| Nov 6, 2022 at 1:20 | comment | added | jsotola | don't solder the wires .... twist tightly and use heatshrink tubing ... the connection will remain flexible ... I've done that repair on a cable harness that moves a lot ... the cable was a low current signal cable ... I do not know if the fix would work for power cables | |
| Nov 5, 2022 at 18:37 | comment | added | DKNguyen | Yeah I had thought about suggesting a splinting with a steel rope cable between two layers of heatshrink when I typed that but thought it might be excessive and too stiff. Zip ties would be more appropriate. I think the "tapered thickness" heatshrink method would be most effective though in maintaining a radius. | |
| Nov 5, 2022 at 18:29 | comment | added | Bart van Heukelom | @DKNguyen thanks for the tip. What I've done a few times when making connections that were allowed to be ugly, was splinting them with something like a disposable chopstick and zip ties. | |
| Nov 5, 2022 at 18:24 | comment | added | DKNguyen | What you do is heatshrink the splice well past where the splice ends so it acts as strain relief so the bends in the wire are distributed over a longer length for a larger radius rather than concentrated at a small point close to the splice where it is more rigid. The more rigid the splice the more rigid the heatshrink should be. Or you can get real fancy and put multiple overlapping layers of heatshrink of different lengths centered around the splice so it is effectively thicker and more rigid as it gets close to the splice. | |
| Nov 5, 2022 at 18:23 | comment | added | Bart van Heukelom | I'm imagining you could get quite close if you connected each strand separately, whether by soldering, crimping or perhaps, knotting. That's just a random idea though, and it would be quite a lot of work too. | |
