Re: Finally!

Be sure to show it off at school in science class --- your teacher and friends should be impressed!

Try elevating the sec coil in 1/4 inch increments to hit the best coeff. of coupling for your particular setup. This should give you 2-3 inch spark gain. I usually obtain 18-19 inches with a 12/30 NST in this configuration.

Well, I've finally got my coil up and running. Special thanks to all
who replied to my queries. Your input was very helpful. Now, using the
Dr. Resonance - modified Freau formula, I should have 0.85 * sqrt ( 360
) or about 16 inch streamers. This is for a 12Kv 30mA neon with a 4
inch Dia. 2ndary. The discharge is actually about 12 to 14 inches but
that's more than satisfactory for the first coil I've put together
since high school. I hope to have pictures up on the web soon and again
I thank everyone for their input.
