ABSTRACT:
Intermediate dogging device to limit lateral deflection of a log held in end dogging log carriage. When a log is machined, residual stresses within the wood, weight of the wood, and sawing forces tend to deflect unsupported portions of the log, reducing cut accuracy. An intermediate dog is mounted on carriage between end dogs generally adjacent central plane containing feed axis. The intermediate dog extends from carriage and engages the log extending between the end dogs to reduce movement of log relative to carriage.
