After spending far too much time on the computer this week, sorting out the forum, I needed to get back to hammering today. This is where I'm at. The larger one is now at the stage where I begin tuning the bottom under, not much more to do...thankfully. The smaller stone resting on top, and upside down, is black because I've just normalised the steel and it's got a covering of fire scale on it. I pickle the pieces in hydrochloric acid to remove the scale prior to raising to that I can see better what's happening to the metal and so that I don't get quite so filthy. Hydrochloric acid removes the scale fairly quickly but is very slow acting on the bare metal.
