In a method for manufacturing a combination investment casting core (22), a plurality of cores (40, 42, 44) are each formed by cutting a metallic sheet to define a first portion (46, 48, 50) and a number of separate second portions (52, 54, 56) linked by the first portion (46, 48, 50). The second portions (52, 54, 56) are bent out of local alignment with the first portion (46, 48, 50). The first portions (46, 48, 50) of the cores (40, 42, 44) are assembled and secured to each other.
