By the invention complex three-dimensional forms in wood, for example, cabriole chair legs, may be produced by a turning method on lathe possessing special characteristics. The process involves supporting a pack of wood lengths for rotation about the lathe rotational axis such that, in operation, wood is removed from the periphery of the several wood lengths of the pack by the action of a tool, such, for example, as an abrading file, the amount and distribution of the wood removed from each wood length being determined by a profile of template means and the spatial relation of the wood-length with respect thereto; displacing at least one of the wood lengths through a certain angle about its longitudinal axis and thereafter repeating the template determined wood removal step. To produce a third such surface in the aforesaid wood-lenght, the wood-length is again angularly displaced and the wood removal step repeated yet again. The template means may be constituted as two template members supported on the lathe bed or base one to either side of the lathe rotational axis. |
