Hello I created this thread for information that I have come across regarding the construction methods and operations of Tesla Coils. My main question is if one places the primary coil in the center of the secondary coil, will the secondary coil produce close to the same amperage as it does voltage. Assuming the wire is a large enough gauge, could I in theory get around 14 amps with a voltage around say 5000? any information from experienced coilers would be appreciated.
Question about Tesla Coils?
By "center of the secondary coil", do you mean WITHIN aka INSIDE the secondary coil, or do you mean half-way up the OUTSIDE of the secondary?
I have been considering a double-ended Tesla, with a primary in the (outside) middle, and a double-length secondary with HV eminating from each end in kind of a push-pull configuration. I am also wondering what would happen if, at the exact center of the secondary, I counter wind the wire the opposite way? I don't think it would work, though, as counter-winding the wire would seem to cancel everything out and yield no output. I think that, in order for the two outputs to be twice as high as normal, it would have to all wind the same direction. (Where would ground be?).
Now, you haver me thinking about making a smaller primary and sticking it inside the secondary tube and seeing what happens. Does "spread" matter? Do primary coils have to be wide, long or what?

My work has been halted at the moment due to moving and other family issues. I have however thought about placing a primary coil in the center of a secondary coil of considerable gauge (thinking of 12 AWG). With some 30 turns. I will make my primary exactly 1/4 the wire length of the secondary coil. The primary should be 4 times the cross sectional area (so double the diameter? of my secondary wire). For this first test I don't plan on using a grounded secondary. I may be wrong in my thinking but when someone grounds the secondary and places the primary at the very bottom I think this "chokes" the ability to produce amperage because it is a direct short to ground, thereby only allowing voltage to be produced??? Again I may be wrong on that.
Wired in parallel across the secondary leads I will place a high wattage resistor (this lowers the frequency of the secondary coil) so I can run this output through a step down transformer. I am curious to use a larger gauge wire because anyone who builds the conventional tesla coil uses very small gauge wire....well no wonder they cannot get high amperage because the wire won't allow it? Finer wire means just voltage. These are my thoughts right now though.
shoot me another message with any more you got I'm always willing to here more.
So, you are looking for volts and amps. It seems to me it's always proportional, ie bigger gives bigger volts and amps (of course, varying either primary or secondary will give variations in output).
As for grounding one end of the secondary, I have found that it needs a "ground plane", which is "something to push against". It helps to think of them as a CB radio; if the antenna has no ground plane, meaning the body of the car, it has nothing to push the signal against.
In experimenting with CBs, etc., I have found that even using a metal tool box full of tools makes a sufficient ground plane (ground mass) to give the signal something to push against. That's why I am using a metal file cabinet for the ground of mine (was using a bicycle).
What I am wondering about is if it's better to tie the low end of the primary and secondary together, as you find in a car ignition coil. So far, it seems to make no difference. Maybe at higher frequency it would.
