Abstract: It is a miter saw table that has adjustable measuring tapes. The tape sections can be calibrated so that the zero point on the tape is always set at the outer surface of the blade. This is done by using slidable wings that can be secured to a base. The wings a readjusted until the built-in tapes match a control tape. Once the wings are set, cuts can be made quickly by either setting a stop at the precise distance needed, or by sliding the board under the blade until the end of the board aligns with the desired measurement. The board can then be accurately cut without having to measure and mark the board first. Moreover, if the blade is changed during the course of work. The measuring system can be quickly re-calibrated to the thickness of the new blade and cuts can immediately be resumed.
