In the other photos I'm thinning down the damascus backspacer. It's hardened but the carbide endmill still cut it. After roughing it on the mill, I finished it to size on the grinder. The stainless damascus backspacer wouldn't hold by itself to the magnetic chuck so the other pieces are there to keep it from moving.
