I'm not a damn animal!!

But I do have a LOT of time spent riding in the rain. And HARD rain at times.
So, I am getting no movement at all using a hammer and a block of wood (what I have available). It seems that a brass punch as big as I need it is not going to be readily available. What are your thoughts on getting a brass hammer, setting that against the shaft and striking the brass hammer with another hammer?
Additionally, is it OK to hit the area with some liquid wrench and let it sit up?

Yes, and yes. It'll take whatever it takes.
The only downside to the brass hammer is if it needs to be driven after you break it loose.
Brass bar not available?...
