Most primaries in nsts use 12 or 14 AWG wire.  Secondaries are #40 or 
#42 AWG.  Usually 1 Volt per turn, so 1/2 of the xmfr at 6 kV on a 12 
kV center-tap grounded nst, would require approx 6,000 turns of the 
very small guage wire.  This is why most of them are wound on a 
computer controlled lathe or similar machine.

If you can pick up a used nst for $50 - $70 you are way ahead of the 
curve in terms of labor, time, and materials cost.
