<p>The disclosure herein describes an attachment assembly for mounting to a conventional bench saw; the assembly comprises a rigid member which is mounted to the power-operated main shaft of the bench saw. The member has two projecting rods at one end thereof which are adapted to slide on a pair of guiding pins mounted on a movable structure of the bench saw; the function of the pins is also to fixedly secure the rigid member to the movable structure after the attachment is installed and the tool is fixedly set for a cutting operation. The cooperation of the projecting rods with the guiding pins is such as to prevent vertical lateral and angular movements of the member which would otherwise appear because of the reaction forces exerted during the cutting operation.</p> |
