Jeff, that may very well be. I tried to clarify that point twice. Once by stating that the original post was not meant to be of high a technical level, and second, to clarify that the hammer-forging machine that I had read quite a bit about used hydraulic impact to do the work. If that's the beef, then we are really splitting hairs. I quite honestly don't know how the current machines are powered. Doesn't really matter, the end result is the same, they are "hammer forged"

There is a very fine line between "Hobby" and "Mental illness"
