Subject: SPARK GAP QUESTION

Hi there and thanks for taking time to read my post.
	
I am using a 15KV-at-30ma neon transformer with a .005 ufd cap, an 18" x
4 3/16" diam secondary and tapered primary -at- 18" diam 1/4 copper tubing.
At present I am getting 28" sparks using a 2 gap spark gap contrived of
3  3/4" ball bearings set to a total gap of .240"

I have built an 8 gap spark gap using 9 pieces of 3/4" diam s 1" l
solid brass rod.  Each gap was set to .030" and ends polished	.  Each
electrode was supported on ceramic standoffs and gaps were accurately
measured for parallelism and spacing.

Question: I have tried both gaps, the 2 gap and the 8 gap with and 
          without air blowing over them and I see no difference in
          spark length or spark strength.  Can anyone make a comment
          or give direction as to the possible reason for this?  
          I have kept everything the same except for changing the 
          different type of gap.
          (I tried reducing the spacing of the multi-gap to .025" and 
          found that the spark length did reduce in length.

Looking forward to any comments, ideas, theories or lies :)
