Abstract: My invention is particularly adapted to saws for cutting metal, and especially abrasive disc saws, wherein the saw is fixed to a shaft which is rotatable within a bearing located at one end of a rocker arm. A drive motor, preferably an electric motor, is mounted on the other end of the arm and the latter is pivoted intermediate the saw and the motor on a bracket extending upwardly from a base. The arm swings about the pivot to move the saw toward and away from the work to be cut, which work is clamped within a vise secured to the upper surface of the base. The improvement herein disclosed comprises a manually settable timing system for adjusting the amount the saw moves in a direction away from the work, after the cut has been made, so that upward movement of the saw is limited to a position wherein the saw is only a very slight distance above the uppermost surface of the work.
