    Put the cassette tool in a vise, squeeze or strap the chain whip against the spokes and turn the whole wheel. You could also rig something to get a longer handle on the chain whip.

    I once had to take out a seriously seized lockring that hadn't been touched for years. I used an old chain wrapped around the cogs (as many as possible) and then secured around an old racquet, itself secured under a huge rock.

    That left me two arms to get a huge moment on the lockring and wheel rim and loosen it. Be careful as once you overcome it the lockring will spin very quickly so you may get a close encouter with some mean cogs, so try using oposing directions like pushing the wheel down and pulling the spanner up as that allows you to deliver maximum force

    if it's the right type of lockring(you use a wrench instead of an insert), you could put the bike in a stand, remove a pedal, put a long pipe on the crank. then use a big enough wrench, possibly with a leverage bar, to remove the lockring.

    if it's the insert type, as said above, put the tool in a strudily mounted vise. get the chain whip on there, and get some form of leverage bar on the end of the chain whip. then just walk the chainwhip around to loosen it.

    Tried using a hammer yet? Seriously, it usually works for me, just hit the wrench holding the lockring, not the chainwhip.

    Also, before I resort to the hammer, I find I can get much more leverage if I angle the chainwhip and the wrench on the lockring so that I can pull them towards each other. Works better when you can put force on both.
