Bundling Wires with Lacing Cord

It’s a minor detail that you don’t usually see, but I like the finished look of neatly-bundled wire harnesses. While zip ties are convenient, they can damage the wire over time – under vibration, the edge of the zip tie chafes the Tefzel jacket, and eventually can cause intermittent connections, or worse, short circuits. Rather than wire ties, I decided to try out using lacing cord. It’s an old technique, but it’s super simple, light-weight, and if done properly, looks really sharp.

I decided to step up my video presence a little so I created a short video showing how to use lacing cord to build a bundle. I built up my main wiring harness this way, and it looks nice. YouTube video is embedded below:

Having finished lacing the main wiring harness, I began installing it into the fuselage. So far, so good.
