-
rotating a camming device rotatably mounted at a location adjacent to a throat opening in a workpiece support surface of the power tool assembly in a first direction to unlock a throat plate; removing the throat plate to expose an arbor shaft with the camming device still mounted; mounting a shaping device on the exposed arbor shaft; inserting the throat plate in the throat plate opening after the shaping device is mounted on the arbor shaft; and rotating the camming device in a second direction opposite the first direction to cam a first camming surface portion of the camming device against a second camming surface potion of the inserted throat plate, thereby locking the throat plate within the throat opening. - View Dependent Claims (13, 14, 15, 16)
