Abstract
A method of fabricating a lamp, wherein the lamp base is made by providing a polyhedral block of wood and cutting the vertical plane faces of the block to form vertically curved sides while still maintaining the straight shape of the faces in the horizontal direction.
Claims2
A method for making a lamp base comprising the steps of:
- providing a polyhedronal block of wood having a cross-section which is symmetrical about a longitudinal axis and having plane faces whose vertical intersections are parallel to said longitudinal axis;
- and
- cutting said plane faces to vary the cross-sectional area of said block along its height and to form sides on said block which are curved in the vertical direction and straight in the horizontal direction, said sides intersecting each other to form curved edges which lie in a vertical plane.
