My chinese airhammer, which is basically a copy of a chambersburg, has 
88lb falling weight, and a 1056 lb anvil- so that is a 12:1 ratio, 
which I think is ballpark for the oldies but goodies like nazels, 
chambersburgs, eries and the like. 12:1 up to 15:1 is what I have heard.
What is the ratio on a 25lb little giant?
