Abstract
A gauge for measuring the extent of alteration in the level of carriage on which a power tool such as a router or saw is mounted. The carriage is mounted beneath a working surface on which a piece of work is placed. The cutting implement of the power tool such as a bit or blade projects through an opening in the working surface and terminates above the surface. The carriage may be raised and lowered and the gauge records any movement of the carriage. A clutch allows the gauge to be manually adjusted without affecting the level of the carriage. A hollow chamber is mounted beneath the working surface and through which the cutting implement extends. Air within the chamber is evacuated in order to create a vacuum for withdrawing debris resulting from the cutting of the work piece from the area where cutting takes place.
