Claims21
Log shaping apparatus for shaping a wooden log workpiece into a finished log having a uniform diameter and a smooth surface finish, comprising:
- a base;
- support means attached to the base for supporting the log workpiece at opposite ends thereof;
- annular cutter head means rotatably mounted with its axis of rotation substantially aligned with the longitudinal axis of the log workpiece, said annular cutter head means having an inner annular opening therein having a diameter larger than the diameter of said wooden log workpiece;
- a plurality of shaper blades fixedly attached radially about the annular opening of said annular cutter head means, the innermost point of the shaper blades determining the diameter of the finished log;
- planar blade means fixedly attached about the inner annular opening of said annular cutter head and set at an angle to the workpiece for finishing the peripheral surface of the log;
- means for driving said cutter head about its axis;
- and
- means for longitudinally moving said log relative to the cutter head means.
