1. A method of forming an orifice through a rail member of a heat shield panel having a cold side surface and a hot side surface, comprising:
positioning the rail member and a hole boring tool at a first orientation, where the hole boring tool is at a first predetermined angle relative to the cold side surface;
forming a first hole into the rail member using the hole boring tool, the first hole extending at least partially through the rail member;
positioning the rail member and the hole boring tool at a second orientation, where the hole boring tool is at a second predetermined angle relative to the cold side surface;
forming a second hole into the rail member using the hole boring tool, the second hole extending at least partially through the rail member and intersecting a portion of the first hole, wherein the first hole and the second hole form the orifice extending through the rail member, from an inner wall of the rail member to an outer wall of the rail member.
