If you're in a rush,then make a small compact circuit,as it doesn't require much components.Mount the MOSFET on a solid heatsink,bend the gate and source out a bit for more space and solder the zener diodes directly on these pins,just like the gate resistor,according to Fumeaux's schematic!Make sure nothing connects to the heatsink expect the MOSFET.Solder short,but enough wires to the potentiometer's legs and solder these to the right points.If you have long enough wire from the base of the secondary coil,solder that directly to the base too,make sure it doesn't touch other metal parts.Use the thickest wire you have as primary for a good magnetic field coupling.

The best way to try out this circuit without blowing up the MOSFET is to use a low voltage source,like a transformer rectified for DC.Add a fluorescent light bulb close to the upper end of the secondary.The first thing to do is rotating the potentiometer and see if the light bulb lights up.If it doesn't,then change the direction of the primary.If it does,find the position where the light bulb is the brightest.After you found the best point you can increase the input voltage.

If the MOSFET blows up you can either have gate overvoltage mainly due to bad zener diodes or wrong connection,or too much drain current.To decrease the drain current you can add a few more turns to the primary coil,but too much turns will decrease the length of the arcs,so use more turns while testing.

For a better design and longer arcs you should read other people's projects here and of course the websites which has most of the knowledge required to build a great Tesla coil,for example:
http://kaizerpowerelectronics.dk/tesla-coils/

https://www.loneoceans.com/labs/

Will try thank ypu very much! And sorry again if i sound demanding :(

How far away should the primary coil be? How many turns should i start with?

The closer the primary to the secondary,the higher the coupling is ,which is essential for SSTCs.As long as you can't see sparks from secondary to primary you can move it closer.

The number of turns is really experimental.If you look at other SSTCs it moves around 10,usually less.

Many things depends on design,so try these instead of making questions that we can't answer...
