The lock ring still has the flats. I tried using a pipe wrench but the lock ring is so thin that the wrench can't get a very good grip on it. I tried using a vise, but when I push/pull on the crank arms all that I end up accomplishing is getting the crank to pop out of the vise.
How would I go about using a hammer and flat punch? Is the lock ring right or left-hand threaded? (can't remember right now)
