ABSTRACT:
A method of cutting an elongate timber web which forms on each of two opposed ends thereof a tapered end shape including a series of at least four cuts at successive angles to approximate an arcuate convex end. The method includes the steps of performing first and second passes of the web through a saw having cutter groups at adjustably spaced apart locations, each cutter group having at least two cutters (101, 102, 103, 104) set to angles so that the cutters of each cutter group correspond to a subset of said series of cuts (201, 202, 203, 204) at a respective end of the web. The web is rotated between the passes, the rotation between passes and the cutter settings together result in a multi-faceted end cut.
