BIG Hammer

My little hammer works so well that I decided to build a much larger version. I generally scaled everything up but kept the same principals in mind. I have heard that the "professional" companies like Kuhn & Chambersburg use a ratio of 1:10 for their hammer head / anvil weight. My anvil weighs 3378 lb. and my hammer head will be 250 / 300 lb.
I am seeking guidance from Ron Kinyon himself for some of the finer points.

Here are some examples of BIG air hammers, followed by some of the steps 
in building my big Kinyon style hammer.

There are 21 fairly good pictures on this page, It will take some time (2 min.?)
to download if you have a slow connection like mine.
