ABSTRACT OF THE DISCLOSURE An improved flying saw of simplified and more economical construction is disclosed which operates smoothly with reduced vibration and which performs in an improved manner at higher operating speeds. The machine has a main crank arm with a rotary saw blade at one end and an adjustable counterweight at the opposite end, a stabilizing crank arm with a counterweight, and a connecting rod causing the arms to rotate in unison. Both arms telescope to permit simultaneous adjustments of arm radius while screw jacks adjust the height of the crank axis relative to the work. The work is supported on a wheel having a special sliding-block eccentric which moves the wheel in a vertical direction to deflect the work into the path of the rotary saw blade. A quick-drop support bracket permits lowering of the wheel and its eccentric away from the path of the work in an emergency situation so that flow from the mill need not be interrupted.
