Subject: My 4 inch Tesla Coil 

Hello Everyone!
 
I'm 14 years old and I  recently built a tesla coil, and I  was wondering if 
it is up to par with the other 4 inch diameter tesla coils out  there and if 
not, how I can improve it. The power supply is a 6,000 volt 30  ma NST, so 180 
watts. The capacitor is an 8000 volt .005 mica capacitor in  parallel with a 
beer bottle capacitor, so the total capacitance is around .01  mfd. I have 
heard many people saying that mica capacitors are very "fragile" and  can die very 
easily, but I haven't had any problems with it whatsoever. The coil  is 4 
inches in diameter and is 22 inches long. The primary is copper tubing 1/4  inch
At best, I can get around 18-20 inches of arcing. Many of the  other 4 inch 
tesla coils I have seen on Youtube have a much larger toroid than  mine, but 
when I add a bigger toroid, the arc gets smaller regardless of tuning.  I think 
this is because my coil is underpowered but I'm not sure. I would  greatly 
appreciate any comments.
