I have not seen it used but in one of the class rooms at Tech there is this gigantic machine.
It is a Tinius Olsen machine that seems to be for testing the properties of materials under pressure. Near as I can figure you put things into that big vise on the left and scrunch it down. Presumably the Big Needle then moves on the Big Dial.
And if that does not give you some useful data, well, see on the table top that thing that looks like a war hammer?
I think you just pick this massive lead block sledge up and start pounding.
