Thanks again for the photos. They REALLY help. I'll go back and give it another whack. Maybe it's time to bring out the small sledge hammer and a heavy duty socket to place on the back of the pin to bang on?
There seems to be a round flat cap on the back of pole piece (see photos). I don't see it in the photo of yours. Does that also get pounded through the hole or do you somehow have to pry it off or remove it somehow first? So far I have not seen ANY movement.
