I've been trying the reverse-rotafix method this morning, but so far no joy If the reverse rotafix doesn't work, then I'm afraid nothing will

*Update*

I soaked the thread interface area between the cog and the hub with WD40 as best as I could. Even after repeated tries of the reverse-rotafix method, its a no-go I'm not a small man and I put A LOT of my 250lbs behind it....and still no joy. If I went balls to the wall and put almost ALL of my 250lbs behind it, I'm afraid I would break it instead of fix it.

But I've now become scarily obsessed with removing this damn thing at the risk of destroying the wheel just to be able to say the damnbastid cog didn't win! Somebody convince me its ok to give it up so I can get a good night's sleep
