With every new knife comes new challenges. I don't see this slowing down in 2017. I need to up my mokume gane game. I bought some proper brass and copper sheets and cut them up into 38mmx38mm squares. I stacked them 23 layers high and began the heat.
I clamped everything between two large pieces of D2.
Everything worked out and the billet is welded. I can proceed with more heats and flattening out the billet.
old clampy got a bit too much heat.
