You can order the parts at many online stores, if you don't have a store that sells these parts around. It's a very bad idea to assemble the device with wires without fixing everything firmly. A simple solution is to use a perforated board, or a simple thin plate of any insulating material (better one that resists heat) with holes for the parts. Better too to first determine which pin is the ground pin, to connect it to true ground, and when drawing arcs move a wire connected to the grounded pin close to the HV terminal, that shall be kept suspended in an insulating support and never touched. Use heat sinks for the mosfets, and be sure that the core used for the series inductor is as thick as the core of the flyback, and that you have more turns on it that the number used in the primary coil on the flyback. Failing to follow this will result in self-destruction of the device.

Well I've just bought another soldering gun, not a very good one but good enough to use temporarily, So I'll order the 2 IRFP260's and I'll find most of the other parts I need.
I have this
Could I use this to power my flyback as it seems it pass 190 of power, my PSU is a 12v 32A so I need some resistor to limit the current to a max of 15A.

It's a good idea to put a resistor in series in the first tests. If everything works, remove it. The circuit will draw just the corrent that it needs from the power supply, not the rating of the power supply.
