    this happened on my king after converting it to ss for a bit.
    1) i was using a cheap thin steel cog
    2) i layed the wheel down on the ground, stood on the edges and pulled the guy off.
    3) i replaced the cheesey cog with a origin 8 cog (affordable, stong, super wide profile, looks nice)

    I would think if you had a chain whip, you could put another cog on there, lightly tighten down the lockring, mount the wheel up on the bike, and use the chainwhip on the second cog in the opposite direction.

    It's on a shimano spline type freehub body, I'm trying to pull it straight off.

    Sean's idea is worth a go.

    It sounds like your cog has embedded itself in the metal of the freehub. By having another cog on it to use as an anchor and then turning your cog in the opposite direction to normal rotation you may (or may not ) free it enough to remove.

    ^^^ This.

    This is about the fourth thread this morning I've looked at, where you've already given the exact advice I would have. GET OUT OF MY HEAD!!!
