After finally finding some good sources on Tesla Coils, I set off to see how well built my previous instructable, "The Simple Tesla Coil" was. My findings were grim, it was performing terribly considering that the transformer draws in 990 watts. So I set out to change that. I would recommend that you skim through my previous instructable before attempting this one.
I suggest that you read the entire instructable before ever attempting to build it. You may end up halfway through and realize that you don't have access to a tool or material, and waste time and money/supplies (I only had to buy the magnet wire this time!).
Step 1: Supplies
Ha! This isn't supplies! This is safety! Please read. I am NOT responsible for any injury, property damage, or death that may occur as a result of you building or operating this device. After reading new sources, I have found that fatality is likely if you happen to touch the line in, or primary circuit, so don't! The secondary circuit is a grey area, you might die, you might not, but DON'T TOUCH ANYTHING besides the off/on switch and keep your distance when using this thing.
Alright, for my supplies I used:
-A 15 kV 60mA neon sign transformer (same one as before)
-16 Snapple bottle salt water capacitors/leyden jars (made more than before, check previous instructable to see how to make these).
-Lots of plywood, 1.5" diameter PVC, and some wheels for the supporting structure (Design your own structure out of whatever you have lying around, its cheaper that way)
-Spark gap from previous instructable (1/2" gap now, made from two bolts through opposite walls of 3" PVC)
-1/4" inside diameter copper tubing, 30 feet long
-Various lengths of HV and/or regular 120V, 15A wire (it works too if you keep it away from other wire to avoid arcing)
-Long metal rod to use as ground (NOT the ground for your house! Bad things will happen to the electronics you love!)
-Extension cord (to stand way back!)
-4" diameter PVC for secondary form -19" long
-800 feet of 24AWG enameled copper wire (aka magnet wire)
-A toriod (previous instructable- 3" minor diameter, 11" major)
