A method for fabricating a turbine inlet casing (10) includes the steps of providing a block (14) having upstream and dowstream facs (26, 28), cutting a circular shaft opening (16) through the block, cutting an inlet plenum (34) through the block along a central axis of the block, cutting one or more distribution ports (18) through the block along the central axis, attaching cover plates (22, 24) to the upstream and/or downstream faces over the passages and ports, making connecting holes (20) between the inlet plenum and distribution ports, making a turbine inlet hole (42), and splitting the block along a line perpendicular to the central axis. |
