ABSTRACT:
A machine for processing wood logs for construction of log houses. The machine includes a power feed to load the logs into a self-centering device. A carriage assembly is centered about the log and the log is mounted in the carriage on powered centers so that the log can be rotated. The carriage travels longitudinally on tracks past one, or a plurality of cutters, which as the log rotates cuts the log down to a selected diameter. After the log is cut to diameter it is again passed longitudinally along the tracks and two cutters are positioned at equal distance above and below the axis of the log to cut tongues and grooves on the top and bottom of the log, respectively. Means are provided for cutting a saddle notch underneath the log, to cut the logs to precise length, and to cut a vertical notch in each end for the purpose of joining logs end to end. Means are provided for rapid removal of the chips cut from the logs.
