Abstract: The present invention discloses an automated rock saw having a saw motor load sensor to control the speed of the conveyors bringing the rock to the saw blade. As the saw motor works harder to cut a given rock, the controller automatically slows the conveyor belts, reducing the load on the saw blade. If the saw blade is easily cutting a given rock and not working at optimum speed, the conveyors will be sped up, increasing production. Also provided in an alternate embodiment is a horizontal blade that can be moved into place to cut the “bottom” of a corner piece, then the standard, vertical blade cuts the other side of the corner.
