New Coil Firing!

 BH> OK,  here's a question,  and I hope I describe it correctly.

 BH> I just got my first coil working,  with the help of          
 BH> everyones postings, (thank you).

Great Work! Please tell us more!

 BH> I wound the secondary on regular PVC pipe (4 in. diameter), 
 BH> which I know now is somewhat of a no-no.  

I have never heard of anyone's first coil being perfect!
 BH> The question is:  the winding stops about 4 inches from the  
 BH> top of the pipe.  There is one sweeping wind from the end of 
 BH> the tight winding up to the top,  where the discharge        
 BH> terminal is.  Does this spread out the capacitance along     
 BH> this long wind, and away from the terminal. I have noticed   
 BH> that there is corona all along this wind, and the sparks     
 BH> seem to get stronger near the tight winding. 

 BH> I am planning to cut off the rest of the pipe anyway,  but I
 BH> am curious as to whether my intuition is correct (allthough  
 BH> I doubt it)... Any kind responses are appreciated. Thank you

The only problems you are having is that: your discharger is
mounted too high up off the top of the secondary winding; your
discharger is too small in diameter; or both.

Cut the coil form down to 1 inch above the winding, and properly
cap the coil. I just use scrap pieces of squarely cut PVC pipe as
insulating spacers to change and adjust the height of the
