as much as with the theory that and nothing one negates the other ?
he said that once it is there for the inductor grounding wire is to never enter there peaks with HV. and here too we have both ends grounded.

Where do these ideas ,as you can see ! what is to be different?

Thanks

Tomtech,  yep, it is weird. In one video he says something and in other he says something else. Better to forget what he says and just keep with the basic principle. Many roads lead to Rome.   Did you see ? In his box he is also using smaller WIMA caps   (I didn't understand the value - something with 0.15 uF ? or so)

What he shows in the movie - using welding cable (26mm2) , Not sure now if he said 4m pipe in the ground. Did you spot the coil on his GND cable? Also in the woods he got 198V, at home he is geting 216V - depends on the ground.
The start of Tesla secondary goes directly to the ground (using thick wire ,  13:02) 
His diode bridge was overheating when 4Kw connected.  He is happy

Okay, maybe you could help me in understanding this one...

The primary on a Tesla coil, it has to be tuned just like the secondary.  The primary needs to work with the driver connected to it.  This is where I have a bit more factors then I'm able to incorporate into a single design.

I've seen all sorts of primary setups, loose coupling, tight coupling, thin wire, fat wire, big copper pipes, pancake style, normal coiled style and even some in between that flare out as they spiral up.

The current setup I have, seems to like a thin wire, pancake wrap with loose coupling.  I do not understand why this is.  The only thing I can figure is the skin effect of the small wire somehow reduces the amperage to where it matches pretty close to the IRFP460A MOSFET I'm driving it with.  Any other configurations I try leads to horrible looking waveforms with poor power transfer.

So TK, can you assist me a little in progressing in just this one little area for starters?  My hope is that I can understand this just a little better so I'll have a decent reference point to work from.

Thanks in advance.

@DogOne,

Te reason most likely is that the thin wire coil is closest to the resonant point of the secondary or one of its nodes, the tuning process for a Tesla primary coil is to find its resonant point since this should match the secondary or be a fraction of it (i.e. 1/4 wave), when it is driven at its resonant operating frequency the impedance (AC resistance) will be highest and reduce power consumption and increase power transfer to the secondary.

Look for a tuning guide on the internet and build the tuning jig for the primary coil, you can use a 555 timer or a signal generator to sweep the coil. Here are a couple of quick hits from  Google.
