A tooling system comprises a plurality of elements (24) arranged in an array, each element being supported on a cross rail (22) and being moveable relative to the other elements in the array. Each element terminates in a threaded support post (25) extending from a first end of the element, and is associated with a corresponding internally threaded aperture in the cross rail upon which the element is supported. The tooling system further comprises an adjusting component in the form of a fork (46) which is driveable in rotation and engageable with an element of the array to drive the element in rotation, upon rotation of the fork.
