Cheex's Hobby Tips: Chaos-style damaged power cabling



While putting together some new Berzerker Champions, I found myself needing to reposition some power fists. I could've easily just used some guitar wire, but I wanted it to look more like the damaged cabling you often see on newer Chaos models. After thinking on it for a bit, I had an epiphany: heat shrink.


Heat shrink is used in electronics to repair damaged wire insulation or to bundle multiple insulated wires together (amongst other uses). When it reaches a certain temperature, the material shrinks, usually by a factor of around 2:1 or so, so you would normally pick a diameter that is slightly larger than the wire you're insulating, slip it over the section you need it, and then apply heat. I happened to have some in a drawer from an old job, but you can get some fairly cheaply from a hardware store or Amazon.


It starts with a Green Stuff tentacle, though you can always use guitar wire, and a length of heat shrink that's just a touch wider than the tentacle. Make sure the GS is fully cured.




I cut out some holes and roughed up the ends of the heat shrink with some clippers and a hobby knife. I then slipped the heat shrink over the GS tentacle and applied some heat: in my case, I simply used a lighter, and held the material a few centimetres above the flame using a pair of tweezers. Not close enough to burn the material or cause the tweezers to get too hot, but enough to make the material shrink. Obviously, you will need to exercise suitable caution with this step!




Being Green Stuff and soft plastic, it is still malleable enough that it can be carefully twisted and pushed into place. If you live in a cold climate, I suggest keeping a cup of hot water nearby, so you can submerge the cable into it every now and then to keep it malleable enough.
