I have a friend (jeweler).
Once he asked me to make him an ingot (two). Material - steel. For those who do not know, the ingot is a simple mold for casting blanks. I drew a drawing on his sketch, I found a plate in the granaries of my homeland and began to do it. Material - low carbon steel or so. More carbon is not needed because the ingot is heated before pouring the metal into it and then it is cooled so as not to wait for a long time. In general, K02301 or DC03 or HFS3 - the most it. All manufacturing operations are performed on the tool milling machine 675. Used two cutters, or better to say, mills of two diameters. Handles are made from some piece of chandelier (if my memory serves me right).
