Re: [TCML] Re: Smallest gauge magnet wire for Secondary?

Hey Connor...

I missed your previous posts, but was wondering what power you plan to 
use on your 12" coil??
Normally a 12" coil is powered by a pole piggie or something 
substantial. To get a ratio of approx. 5:1,  with about 1300(18g) - 
1000(16g) turns, the wire size would be more in the range of 18 - 16.

From what I have heard, space winding reduces the L ( inductance) of 
the coil and increases the frequency of the secondary and reduces the 
output potential...
