ABSTRACT:
A process and machine for reconfiguring the surfaces of a construction log (10) used in the construction of log structures to produce a log having the appearance of a hand-hewn log. The process includes a first step (30) of chamfering at least the upper and lower forward edge portions (22 and 24) of the log body (12) to produce upper and lower irregularly beveled forward corners (22') and 24'), and a second step (34) of cutting a plurality of indentations (38) into at least the front surface (18) of the log body (12) to produce an irregular front surface. In the third step (48) of the process, the front surface (18) of the log body (12) is scored with a plurality of cuts (54) to mimic the scoring pattern left by hand-wielded hewing tools. The hewing machine comprises a support structure including platform across which a log is moved. The machine also comprises a first cutting means supported by the support structure for chamfering at least two edge portions of the log simultaneously to produce irregularly beveled corners, and a second cutting means supported by the support structure for cutting a plurality of indentations in at least one of the surfaces of the log.
