A veneer lathe having power spindle means for rotating a log on the spindle axis, a knife carriage disposed for movement transversely of said spindle axis, a knife rockably mounted on the carriage for movement laterally of the spindle axis, means for adjusting the pitch of the knife as it is moved toward the spindle axis, and means for correcting the pitch adjustment in accordance with lateral deflecting forces on the knife. A sensing device mounted adjacent the knife utilizes lateral deflection of the knife edge during the veneer peeling operation to generate a signal indicating the direction and amplitude of the deflection. The signal may be applied directly to a suitably calibrated deflection indicator. It may also be amplified and utilized to effect a correction in the pitch adjusting means so as to maintain the lateral forces on the knife in approximate balance, with a slight bias toward the wood.
