First run 6.5" coil- odd results? (fwd)

Subject: First run 6.5" coil- odd results?
Since I'm new to the list, let me introduce myself. My name is Scott,
or "Lugnut" and I am very new to coiling. I wanted a good start, so I made
and bought everything for my coil, except for Xformer...:_( Chances are I am
doing something wrong but don't know it. I heard that my results were odd due
to my Xformer, tell me what you think.
Well, here's my stuff: right now I'm getting 8" sparks maybe 9".
secondary-6.5" OD PVC 1/4" thick wound to 26" 22 or 24 gauge...I
primary- flat pancake, 1/4" copper tubing spaced 1/4"
13 turns total.
capactitor- salt water type, 15 totally assorted bottles in a 10
gallon fish tank-no oil and I'm not getting flashover. Probrobly due to
my transformer's lack of power.
Xformer- right now I have a horrble, beat up, but working 4000 volt
Spark gap- 4 gaps at about 1 millimeter each.
There are no bypass caps or safety gaps.
Discharg terminal- Use everything from a nail to a 7" sphere. After
tuning, I get the best results from the sphere, about 8" sparks. I have
to use a nail to get sparks to the air, they get about 6" in the dark,
(really dim, but I can feel, them <ouch!>.
Problem- I have no real idea if I am doing well or not because nobody
that I've heard of uses the weak transformer that I have. If I buy two
12kv-at-30mA NST's, will I get 12x the sparks? That almost sounds
By the way, I'm 14 and showed my science teacher, she looked at it like
I was doing something wrong...hmmmmm...maybe I am. Please help me out
or even comment on my coil. I even need a name of sorts...you people
are the best!
