Abstract
A machine for processing wood logs for construction of log houses. The machine includes means to load raw logs into a self-centering means, whereby a carriage assembly can be centered over the logs and the log is mounted in the carriage on powered centers, by means of which it can be rotated. The carriage travels longitudinally on tracks on a linear frame past a plurality of rotating cutters. As the log rotates the cutters cut the log down to a selected final diameter. The carriage is then run back to its starting point, the centers are locked so that the log cannot rotate and two cutters are positioned at equal distances above and below the axis of the log to cut tongues and grooves on the top and bottom of the log, respectively. Additional means are provided for cutting a saddle notch beneath the log, to cut the logs to precise length, to cut a vertical notch in each end for the purpose of joining logs end-to-end, and means for longitudinally slitting the log.
