To all coilers,

I am [and have been for some time] working on my first large coil, for 
use with my first pole-pig. I had thought I had an ideal secondary form 
but closer inspection reveals otherwise. I borrowed from work two 
plastic rubbermaid trashcans. These appeared to be quite sutable for 
coiling. I just stacked them and realized they have differing diameters 
between the top and bottom of the can. There dimensions are 17" tall, 
13.5" diameter (base), 14.5" diameter (top). I have two of those. I am 
not sure how this slight angle will effect performance. And if it is ok, 
I was planning on stacking two of them for a ~14"x54" secondary. So 
would it be better if the larger dimaters were together at the middle or 
at opposite ends; for example curved in at the middle or curved out at 
the middle?

Thanks,
