I tried 550 paracord that I got from Michael's on my 4x24 AWG wire, it was too small. Where do you get your paracord? And please go into detail about using hot glue and heatshrink together. And how do you keep the ends of the paracord together on the wire; like so it doesn't slide up and down the wire and unravel; i used clear tape and heatshrink, but I feel I could do better.
fleaBay is my source. There's plenty of US seller selling mil-spec type III.
For hot glue and heatshrink, I just add a thin coat of glue to the surfaces that will be covered by the heatshrink. The hot heatshrink will remelt the glue and give you serious grip. If you are doing heatshrink strain-relief on a connector, don't add glue all the way to the end, otherwise the heatshrink will not be very flexible where the cable exits it.
