>From my experiments with my own coil, I have found that the 
surface smoothness of the top hat makes a big difference in spark length.
My coil uses an old fan cage about 30" dia. by 6" thick. It is covered 
with aluminum exhaust pipe repair tape. the surface is about what what 
you'd get if you crumpled some foil and flattened it out again. I could 
get 3ft sparks at the current power level (2kw). I noticed that there was 
a slight "corner" where the 2 halves of the cage came together at the 
outer rim. I put some foam weatherstrip on this corner and covered it up 
with more foil tape to smooth it out some. The spark length increased to 
4 ft without any other changes
