    The area around the freewheel pawls is the best place to grab with the
    vice. If you take out the pawls, there should be a flattish surface to
    grab with the bench vice.

    Grip the wheel tightly so it doesn't twist, and unscrew the hub from
    the freewheel. Breaking it loose sometimes takes a real heave (I've
    seen heavy workbenches knocked over), but I've never had this fail.
