A 90 degree angle is used in Tesla Magnifiers, but on a two-coil system, you are more likely to hit the primary with a spark from the secondary if you make the angle too large. As long as your fairly flat primary couples well to the secondary, then you don't need a larger angle. In fact, from what I have read, a totally flat spiral will work well, and is simpler to construct than the banked type. Steve Falco
