I'm not sure if many people would appreciate my reasoning but I decided that I could make a slightly tidier job if I used a twisted pair cable to connect up the sub-woofer in Shelley's car, rather than a long RCA (phono) cable and an adapter.
I could buy twisted pair cable but for a one off job I decided I might as well make my own. To that end, I rigged up a tool out of short lengths of timber and some spring clamps.
I use the spring clamps and timber, rather than the vice, so that the cables do not get crushed. I use the same thing when holding wires to be soldered
I spun one end by hand, doing about 40 full turns per metre of cable length. When I stopped to add more length, I put a bit of tape round, just to keep the cables together. Cable gauge and twists are all guesswork but I'm confident it is better than I need.
It took less than an hour to make over 5m, including cutting the timber and threading the outer sleeve.
