Abstract: A shaping apparatus for shaping a workpiece. The apparatus comprises first and second pairs of shaping members and a spacer located between the first and second pairs of shaping members. The first pair of shaping members comprises a material having a first linear coefficient of thermal expansion, and the second pair of shaping members comprises a material having a third linear coefficient of thermal expansion. The first linear coefficient of thermal expansion is higher than the second linear coefficient of thermal expansion such that on heating of the apparatus, thermal expansion of the shaping members causes the first pair of shaping members to expand outwardly, and the second pair of shaping members to expand inwardly.
