At a CBA demo years ago, Rick Smith drew out a billet of fancy pattern
welded steel in one or 2 heats using a big hammer ( 6-7#s? or more). He
struck so many hard blows for such a sustained period that the
spectators started rubbing their arms and shoulders unconsciously.
He was not a real big fellow and i was amazed.
It looked like he didn't begin lifting the handle at the moment of
impact like i usually do, but rather, waited while the rebound rotated
the handle to a nearly vertical orientation. So when he began his lift
the hammer head was oddly close to his chest, balanced atop the handle.
Then he shoved it straight up as high as he could reach on his tip toes
before jerking it back down to start the down stroke. Almost seemed like
he was hanging from the handle at the apex.
He moved a very impressive mass of steel...
No Jerry, it wasn't Handel's 4th movement...he did that in private..pf
