ABSTRACT:
Apparatus for the precision cutting of lumber from logs by an attached chain saw, the apparatus comprising a frame, a rectilinear guide member mounted upon the frame, and a carriage mounted for longitudinal movement along the guide member. The carriage carries a chain saw adjustment control assembly which may be laterally set to precision cut slabs of a predetermined thickness from a log; which may be vertically set for cutting through logs of varying thickness; and which may be angulary set for greater cutting efficiency of the log. Log jacks and log dogs attached to the frame to prevent movement of the log relative to the frame may also be provided. The carriage may further be provided with a winch for pulling the cutting bar of the chain saw through the log.
