lf your table saw’s blade is parallel to the miter slots, try this easy way to set the miter gauge for making perfect 45-degree cuts. Unplug the saw and lower the blade below the table. Lay a carpenter’s square on the table with one leg butted against the miter gauge. Adjust the miter gauge until one edge of the miter slot intersects the two legs of the square at precisely the same measurement—the larger the measurement in inches, the more accurate the 45-degree miter gauge angle. Way cool!
