Thanks for the comments.  I am currently using two threaded rods as the
spark gap.  I have no fan or anything like that at present.  I did make a
quite elaborate multi gap spark gap out of about 7 short lengths of copper
pipe.  Strangly enough, when i use this spark gap I get no sparks from the
top load whatsoever and the sparks going across this spark gap seem quite
tame in comparison to the single spark gap.
 
If I open up the single spark gap too much it start setting of some rather
alarming pops and banks in my beer bottle capacitor bucket and I have no
idea what that is happening!!  It scares me.
