Twisting stranded cable with your fingers in preparation for tinning and/or soldering is practically a reflex for people making electronic assemblies. however what if the wires are as well close to get your fingers around, or you have the fingers of a sumo wresters? Well [DIYDSP] has a service for you (see video below the break) that’s simple to make from a shish kebab skewer that’s most likely rolling around your kitchen area drawer. The reason that [DIYDSP] wished to twist such carefully spaced wires was to solder a length of 0.1 in O.C. stranded ribbon cable television directly onto a PCB pin header pattern.
The technique is extremely simple. Drill a long hole in the factory-cut flat end, complied with by utilizing a countersink bit to provide a conical taper to guide the wires in. [DIYDSP] discovered that a 1/16 inch (1.6 mm) drill bit was a bit as well big to grip the kinds of wires he was using, as well as lastly settled on a 0.6 mm bit. If you are utilizing larger wires, you ought to experiment to get the best size, or just develop a handful of these of differing diameters because they’re so simple to make — just mark them clearly so you don’t unintentionally grill shish kebabs with them on the BBQ.
The resulting tool is not unlike the company end of a hand-held wire-wrap tool, however works different principle as well as is a fraction of the cost. If you do any type of amount of interconnect wiring with stranded wires, then you ought to inspect out this video as well as whip up a couple of these to throw in your tool box.
