Also need to consider the square inch of press...  2 tons over 1 Square inch isn't hard, considering a high heal shoe spike can apply ~1 ton pressure over 1/4" sq.....

In this case it is quite a lot.

I don't understand the high heel analogy, could you help me? Is the wearer very large, or are you referring to stomping or something like that?

Well, that's a bit of an exaggeration, but right in principle...

If a person weighs 200 lbs is standing on 1/4" spike, that's 800 psi. Doesn't quite work out that way, because SOME weight is on the front of the shoe, and there are two heels. If you narrowed the heel down to a real spike, pointy and all, could clear 2k psi easily, I suspect.

Yes, but to show the "point", that you Also need to consider the "square inch of press" are you pressing more than 1" square? or less
1" sq. is 16 1/4" sq. ( 4X4), so 16 X 200 is 3200#, (granted she is standing on 1 heel.)  something to think about...

Except, gentlemen, psi isn't relative to the presses rating or to the way it increases power.

It is two different concepts and isn't usually used when talking about this type of work /tool.

If you are talking hydraulics, especially closed systems, then we are in business. And I can help a lot there. Thats what I get paid to do.  Well, that and being eye candy.
