     Okay after I install my twin MOT system I will retune my 6" coil.
     Other then that if I make a 3 inch coil it should be in a 1:6 ratio
right? So then it would be 18inches high. There should then be about 1200 -
1400 turns. So 28AWG is .0126" dia and it would be good. 28AWG should leave
me with 18/.0126 = 1428 turns. Then with insulation there will really be
around 1300 something turns. How does that secondary coil sound?



I suppose it is OK.  It's somewhat similar to my TT-32 coil which is
3.25" dia x 17" tall, wound with 28awg.  I don't really like the coils
to be too narrow for whatever reason, so I used the 3.25" dia.
Whether it helps or not I don't really know.  These small coils
tend to be not quite as efficient as one's that are a little larger,
and they tend not to meet the results given by my spark length
formula.  Figure 10% to 15% below the formula results for such
a coil.  It really comes down to building it and seeing how it
works out I guess.
