ABSTRACT:
A method of manufacturing a staircase handrail volute, comprising the steps of: (a) cutting a workpiece from wood with a bandsaw such that the workpiece has an approximation of a shape of the volute, wherein the approximation dimensions are larger than the shape dimensions; (b) mounting the workpiece so that the workpiece may be operated on by a numerically controlled machine tool; (c) cutting a bottom surface of the workpiece to the shape dimensions with the machine tool; (d) cutting lower side surfaces of the workpiece with the machine tool to a first dimension between the approximation dimensions and the shape dimensions; (e) cutting the lower side surfaces of the workpiece with the machine tool to the shape dimensions; (f) drilling at least one mounting hole in the bottom surface with the machine tool, the at least one mounting hole for holding the workpiece in steps (g) through (j); (g) turning the workpiece over and mounting the workpiece so that the workpiece may be operated on by a numerically controlled machine tool; (h) cutting an upper surface of the workpiece with the machine tool to a second dimension between the approximation dimension and the shape dimension; (i) cutting upper side surfaces of the workpiece with the machine tool to the shape dimensions; and (j) cutting the upper surface of the workpiece to the shape dimensions with the machine tool. Other systems, devices and methods are disclosed.
