A tool support incorporates height adjustment and locking features in common components. A pivoting door is used to control the engagement of a height adjustment threaded shaft with the bearing flange of the power tool, with the position of the pivoting door controlled by a manual actuator. In one position the manual actuator allows the door to pivot outward to disengage the height adjustment shaft from the bearing flange. In a second position the manual actuator moves the door to engage the height adjustment shaft with the bearing flange to permit “micro” height adjustment by rotation of the height adjustment shaft. In a third position the manual actuator presses the door into the height adjustment shaft to effectively lock the shaft in position.
An extension is configured to be removably coupled to a base of a bench top power tool or work bench by a connection such that an upper surface of the extension is coplanar with a work surface of the bench top power tool or work bench. The extension is configured to be movably coupled to the base to support workpieces of varying shape and size that do not fit easily on the work surface.
