Here's a makeshift jig for holding 8 strands... Also, somewhere in my box of pro use cables I have a set of 35' speakon cables (about 40' before twisting). I needed 4-pole cables but the only 4-wire stuff I had was 14awg and I wanted at least 12awg, so the solution was to double up the wires and twist two long runs together (twice, because I needed a pair of them). Ok so each big cable has 4x14awg inside, and here I am trying to twist two together. Even working in halves holding down the middle with a stack of textbooks, I've got the wires stretched out across the basement floor and am "whipping" them across and over each other. Every four or five whips, stop and "push" the twists up to the top, then repeat. Whodathunk doing a "simple" 2-wire twist would take me a couple hours to finish.
