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.
