A method of manufacturing a rotating component (110), the method comprising the following steps: providing a component comprising a first portion (20, 40, 60, 80, 100, 116), which first portion defines a first cavity (26, 46, 66, 86, 106), characterised by; identifying a first inertial property of the first portion and/or the entire component, introducing material (28, 48, 68, 88, 108) into the first cavity to achieve an adjusted inertial property of the first portion and hence a desired inertial property of the component. A rotating component (110) comprising: a first portion (20, 40, 60, 80, 100, 116) defining a first cavity (26, 46, 66, 86, 106), a second portion (118) defining a second cavity, the second portion being circumferentially spaced from said first portion, characterised in that the first cavity has a first material (28) deposit therein, said material having predetermined inertial characteristics so as to adjust the centre of mass (Z) of the rotating component.
