Case Smithing: Getting Started with DIY Cable Sleeving - Heat Shrink and Final Steps

By: John Williamson | Guides | Posted: Jan 29, 2013 5:38 pm

Heat Shrink and Final Steps


This is around the point where you are cursing undertaking the project and your fingers usually really hurt, but power on, we are almost there! All that's left to do is fix the sleeving in place and reinstall the cable into its home connection.


Take two pieces of heat shrink and slide them down over the cable pin and sleeve. If you find the sleeve end is fraying or too thick, wrap some clear sticky tape over the end of the sleeve and wire, as tightly as possible. This should make the cable almost like a funnel hopefully allowing the sleeve to pass over.




Aligning the sleeve and heat shrink is easiest to explain with photos, so to begin level the sleeve up around 2mm down from the pin clamp.




Holding the sleeving in place adjust the heat shrink so it also sits 2mm behind the pins that grasp the cable housings.




Double check that the shrink is grabbing both the sleeve and cable pin - it also needs to be as straight as possible. Using an even amount of heat from your heat source, either turn the cable or move the heat source around the heat shrink to make sure every side is exposed to heat and allowed to shrink to its full potential.




While the heat shrink is still hot reference the cables position via your connection diagram and insert the cable into its matching location. Repeat the process on the opposite end for modular cables.


For non-modular stretch the sleeve to the opposite end of the cable and line up your heat shrink so that it's half on sleeve and half on wire. Then shrink into position. Enjoy for a few moments then rinse and repeat...
