I'm in Henderson, Biggundoctor. I have seen the Nevada thread and know that you need a bigger anvil to back up the hammer blow to work easier and faster. What I want to know is the physics behind why a bigger anvil moves metal better. Luckily, I think JHCC caught the drift of my rather poorly-worded question, and seems to have cleared it up. However, I'm asking in relation to physics, so if I find other pieces of evidence that contradict his theory, your theory, my theory, and at least 3 basic laws of science, I wouldn't be surprise
