Default Re: Traditional ways of tying cables together.

I have used silk thread that works very well too.

One thing to remember, about lacing wires into looms, the not so obvious: Some wires do not belong in a loom.

These are ones in high Z low signal level parts of the circuit, that are prone to stray pickup, or affected by increased capacitance. Binding them close to others carrying AC signals or just other wires, is a very bad idea.

The worst example I once saw of this was a wire leading to the control grid of a CRT. While the AC cross talk wasn't too bad because the sensitivity of of the CRT grid is not high for any significant changes in contrast, the capacitance had increased so much by lacing it into a loom, that the HF response of the image was significantly degraded. This application is better with a free wire with small supports in occasional places to keep it way from other wires and the chassis.
