Hi All,
   I'm in the process of designing my first coil.  I'm a junior in 
EE and it just caught my intrest while I was researching HV 
transmission lines.  I have a 15kV 60mA NST and I'm reading as much 
as I can about the rest of the design before I actually buy/build anything.
   My question is what is the difference between making the primary 
wind outward away from the secondary opposed to winding vertically 
keeping the windings all the same distance from the secondary.  Also 
what does primary placement around the secondary effect.  If I move 
the primary up to the middle of the secondary what will that effect?
