A slab core is positioned within the drag mold portion. The slab core is configured to define at least in part perimeter boundaries of the at least two upper yoke mold cavities and the at least two lower yoke mold cavities. The cope and drag mold portions are closed with the slab core therebetween. The method also comprises at least partially filling the at least two upper and at least two lower yoke mold cavities with a molten alloy to form a first, second, third, and fourth yoke.
