Wow, thanks for the offer to machine me a new ram bolt - that is really very nice. But, I can do that for myself when I can get to my shop, which is when I will find out if heating the existing pin with a torch will "kill" any Locktite and let me salvage the existing ram. I agree that the any new bolt does not need to be harder than a regular (2 grade) bolt.
I am pretty sure from looking with magnification at the junction of the pin with the ram screw that the pin is a separate piece. And, I did seem to get penetrating lube into the gap, because it smoked pretty good later when I heated the pin with a soldering iron.
I will post whatever finally happens. Thank you all for the suggestions and offer of help.
