I know this is a real long shot but I want to put a pneumatic drawbar on my Bridgeport, but i only have like 4.5 inches from the top of the drawbar to the ceiling so a butterfly impact just won't work so i was thinking of an air ratchet. but before i spend time trying to design a way to mount it I thought i would ask here if anyone has already done it and if they might have pics or plans.. thanks
