For twisted wire take a piece of wire about 12 inches long, fold it in half and pinch the fold with pliers. Take that 6 inch piece and put the folded end in a drill chuck and tighten it down, take your pliers and hold the two free ends together at the tip pull them tight straight away from the drill Chuck, and spin the wire with a drill. Keep spinning until the wire begins to pull toward the drill. Allow it to pull. More often than not part of the wire will break either at your pliers or the drill chuck. That's as tight as possible, but if that doesn't happen don't spin it tightly enough that the wire begins to kink, its a feel type thing but super easy to get the hang of.I already have the 26g kanthol but I have no clue how to do a dual twisted. But I will definitely try it out. Right now I have a macro coil that a friend made for it and it is 3mm in diameter
