ABSTRACT:
A structural element comprising a first member and a second member interengaged with one another. Each member has an inner layer formed from a machinable material and having a substantially smooth outer surface, and an outer layer having a substantially smooth inner surface of a shape generally complementary to the shape of the outer surface of the inner layer. The inner and outer layers are joined together such that the outer surface of the inner layer and the inner surface of the outer layer are in substantially continuous, face-to-face engagement with each other. The inner layer of the first member has a first formation machined therein. The structural element further comprises an element for interconnecting the first formation of the first member with the second member thereby to form the structural element.
