God I hate to agree with this as I normally use a chainwhip for either installing or removing a cog, but I must admit that the Rotafix method applies more force than a standard chainwhip. If this method doesn't work you will need to resort to cooling the hub in the freezer and then heating the cog with a torch.

Just wrap a shoprag around the BB shell under the chain. You will not deform the shell.
BTW: You can build a chainwhip with just a couple of short pieces of old chain and a $2 piece of flat stock from Lowe's. If you are going to ride FG you will need one.
