Abstract
A method of manufacturing a metal member includes the steps of forming a metal body having a hollow core, wherein a side of the metal body defines a core opening exposing the hollow core; placing a filament through the core opening into the hollow core; closing the core opening around the filament; and heating the metal body so that the filament disintegrates to form a filament hole sufficient to allow gas within the hollow core to escape through the filament hole.
