ABSTRACT:
An apparatus having adjustable saws for wood cutting. A cutting head has at least two spaced apart disk-saws for producing respective slicing cuts in an article of wood, the saws defining respective distinct outer cutting diameters. Preferably, the disk-saws are bolted to the cutting head and spaced apart therefrom adjustable amounts by interdisposed control plates of predetermined thicknesses. Preferably, a first one of the disk-saws defines an annular ring having an inner diameter, and the outer cutting diameter for the first disk-saw is greater than the outer cutting diameter of a second one of the disk-saws. The outer cutting diameter of the second disk-saw is then less than the inner diameter of the first disk-saw, so that the second disk-saw is nested inside the first disk-saw while remaining axially displaceable therefrom. Preferably, the cutting head is relieved behind at least the cutting teeth of the second disk-saw to permit sawdust that migrates past the second disk-saw, into the space defined by the inner diameter of the first disk-saw, the second disk-saw and the cutting head, to exit through the cutting head.
