  1. Can someone answer a question? Which metal in a damascus billet should be on the outside of the stack if you are using 1095 and 15n20??

      If you want even layers, then the bottom and top of the stack on should have opposite types of steel (i.e. 1095 on the top and 15n20 on the bottom).

       

      The reality, of course, is that if you're going for anything like a high layer billet, and you've started with thin steel, you'll probably grind away bits or all of the top/bottom layers during the grind clean/chop/stack/reweld of the pattern welding process. 

       

      Don't worry too much about this. I often double stack layers with the same steel, or add a thick bar of another type of steel, to initial stack for texture variation. 

       

      The predominate metaphor for pattern welding is wood grain, so imagine a really nice, polished surface of hardwood. The irregularity of the grain is part of the beauty. If it was too even, too precise, it wouldn't work. 

       

      Luck!

      As a rule, not so much the steel type but thickness is the issue- if you have great degrees of difference in the thickness, the thicker pieces should be on the outside in my experience.
