When Ibssen finished making the wooden molds for the revolver, he took them to Gerd's workshop where Einar and Seren were already meeting.
Upon arrival, Einar placed the pieces of wood in sand to create the mold where the molten steel would be poured.
When he finished making the sand mold, he took out the wooden pieces and sealed the wooden container with metal clamps.
Later, they took the mold to the steel factory where, from a blast furnace; they poured the molten steel into the wooden mold.
They waited a few minutes and when the steel had solidified; they removed the wooden presses to be able to open the wood that had the sand inside.
When the sand was cleaned, it revealed a steel mold with all the parts joined by steel wires, like a kind of model kit that only needs to be cut and assembled.
Taking the piece of steel to the water, they waited for it to cool down when it was already cold.
