Let say you start winding from the base (not practical but to simplify explanation) and continue CW toward the apex. Now you move wire (bend) from the apex toward circumference and continue winding down, toward base keeping CW direction (motion of your hand). This is your first coil set. Second is done the same way (starting from the base and winding up) but you go CCW. Now you have two sets which be positioned close to each other. At least this is the way I understand.

. Looks like the cone apex have more influence. can you feel anything with the base side, Vtech?
