An assembly in the form of a press for holding a conventional hand-held portable gasoline engine powered masonry cut-off saw. The assembly includes a vertical frame secured to a pan and on which the cut-off saw is pivotally mounted. The frame is detachable for ease of transport and shipment. A gas bias spring acts to normally position the cut-off saw up and away from a movable work table positioned on the pan. A support plate affixed to a pivot shafted mounted on the frame includes means at both ends for positioning and firmly holding the saw in place during a cutting operation. The speed and on-off control of the saw is provided by a twist hand grip throttle mounted on the outer end of an operator actuated lever arm secured to the pivot shaft. The twist grip throttle is coupled by means of a cable to a trigger actuable blade speed control assembly mounted on the hand grip at the rear end of the cut-off saw.
