A saw attachment mechanism (600) includes at least one guide roller (605) configured for releasable engagement with a track, a guide roller shaft (610) and a guide roller pivot (115), each coupled to the guide roller, at least one pushrod (120) configured for engagement with the guide roller shaft (610), and a cam shaft (135) coupled to a handle (140). The guide roller (605) can rotate around a guide roller axle (610'). The guide roller pivot (115) is coupled to the one guide roller to allow rotation of the guide roller and guide roller shaft (610)toward and away from an engaged configuration. The pushrod (120) can engage the guide roller shaft at a first end and the cam shaft at a second end. As the cam shaft (135) is rotated, the pushrod (120) slides to engage the guide roller shaft (610), to swing the guide roller shaft into an engaged position. |
