The T-bevel or bevel gauge is another tool used for marking and laying out angles. The tool comes either with the blade pivoted to the middle of the wooden stock, or with the blade slotted so that it slides along the pivot. To draw an angle, the wing nut or screw is loosened, the blade is scr to the required angle against a protractor, the nut is retightened and then the angle can be transferred to the workpiccc. Remember that for any single setting, you always have the two angles that go to make up 180 degrees.To verify an angle from an existing workpiccc, or to read off an angle from a drawing, the nut is loosened, the blade and the wooden stock are pushed hard up against the workpiccc in or over the angle, the nut is retightened and a protractor is used to check the resulting angle.
abo/e: Use the protractor to set the sliding wooden stock of the bevel is held hard up bevel blade to the desired angle. against the edge of the workpiece.
