The aforementioned have contributed financially to the continuing triumph of 4hv.org. They are deserving of my most heartfelt thanks.
My tesla coil is very much a fail coil. Even with a grounding stick near it, it only makes an inch of a spark, without, nothing comes. I had imagined a million volts arcing across garage when I first planned to build it. Even if I am not able to achieve that, what can I do to make my 16 inch ,3.5 inch diameter coil with a 7.5kV 30mA NST and leyden jar caps work before school starts (August 22)?????? :D

You definatley need to make sure it's tuned to the correct frequency and everything, resonance is key Look through this -http://deepfriedneon.com/tesla_guide.html and this- and you should be able to get streamers a good foot or so with some minor modification.

As everyone else said, tune for resonance: L_pri * C_tank = L_sec * C_sec, where C_sec is the self-capacitance of the secondary + the capacitance of the topload. Secondary specs?
Yeah, I've seen people on YouTube with these makeshift tesla coils that don't do anything but hum unless you put a grounding wire near it. Look through the guides on DeepFriedNeon, they are very helpful and that's how I'm designing my first SGTC.
