Doug, I had to break out a new sweat band.
Chris and I concentrated on the three problem areas of forging a blade. The tip, the choil, and the ricasso/tang transition. Although we did use the power hammer some, we either went back to the hand held hammer or discussed what to do to prevent problems when using the hand hammer.
For instance it's common for the newer guys to get fishmouths when shaping the tip. Drive the corners inward first. Then we wanted to get the bar hot through and through so the middle of the bar is moving at the same rate the outside is. If not, we would be mushrooming the hot outside over and around the not so hot inside core of the bar. Hard blows go deep to move the middle. Once it's going our way, we can slow down and lighten up the blows till we need to move to the choil or to pinch down the tang.
Most new guys are reluctant to hit it as hard as they need to when they need to and THEN knowing when they are about to go too far. Chris and I worked on getting a good feel for the steel moving under the hammer and developing good forging habits. He done real good.
