The saw frames are adjustable by rack and pinion controlled by handwheel with locking device, and a flat scale marked off at the mill shows distance between saws at all times. Saws used vary from 42" to 50" in diameter. A special centering device operated by 6" steam cylinder is used to place logs to best ad- vantage on track before going through the saws and the slabs coming off behind the machine are taken care of by means of chains or rollers. The drive for feed chains which is variable is controlled by Sawyer and can be stopped or started at will. Standard length of track supplied when cutting 16 ft. logs is 56 feet.
