been there done that.
I did a few hundred turns of 0.15mm wire on a piece of plastic pipe and got up to 10cm long arcs with around 600 watts input, voltage out was about 1-2kV with a current of a few hundred mA.

Yes, I have a core, but a lot of them have weakened due to alot of excessive heat..
Could I use a ferrite rod?
Going to have to source some wire, it's hard to wind too, I tried winding a TC secondary, but about 200turns in it snapped... I could use a variable motor...

Use the wire out of the de-guessing coil from an old CRT, that is about 26SWG and it is where I got my wire from when I made my homemade flyback.
I don't think a ferrite rod would work. The flyback ferrite cores you have will be fine, one of mine had a big chunk snapped off of it yet it still worked when I taped it back on as its only magnetically completed to the transformer.
Off topic but I have been awake for 40 hours straight so I am off for some well deserved sleep now.

Yes I will use a flyback core, anyway I have some old TV's so I have wire, but it's very thick and I tangles alot when I try to get it out from the TV...

I got this from 9 layers of so many turns of 0.2mm wire , i used lego to make a winder for it , didnt take long :D , i used standard A4 paper amd mineral oil to make the transformer and a small ferrite core , driven via ZVS at 40 volts .
