It is really very easy, it is a fancy name for something crossed wraped. Wrap the first level at a 22.5 degree angle and on the return wrap second layer just the opposite. Do this with bifilar wire and at put the green or red wire to the start of the oppsite color, that makes a dual primary coil. I did post some pics of a bifilar wraped coil of Tesla's design.
Right now my PC is down so I can't draw a picture of it the best I can do is walk you through it as I just did. Hope this helped some,
