A tooling system includes a plurality of elements arranged in an array, each element being moveable longitudinally relative to the other elements in the array and having a first end. The system further includes a device, adapted to adjust the relative longitudinal positions of the elements such that the free ends of the elements define approximately a desired surface contour and a device for retaining the elements in their adjusted positions. The first end of each element may be provided on a machinable portion removably mounted to a base portion, the arrangement being such that the free ends of the elements can be machined to produce the desired surface contour. The tooling system may include a plurality of elements arranged in an array, the elements of the array being movable between a closed position in which the elements contact one another and are secured in position, and an open position in which the elements of the array are spaced apart and are capable of vertical movement relative to one another, wherein it also includes a drive device for opening and closing the array.
