Layout Horizontal Lines
(1) Set the surface gauge to the desired dimension.
(2) Place the edge of the work from which the line is to be scribed on the surface plate.
(3) Hold the surface gauge down on the surface plate.
(4) Draw the surface gauge along with the work in the direction of arrow to scribe the line. Push will cause the scriber point to dig into the work which will result in faulty layout.
(5) Reset the surface gauge along with the combination square rule for each dimension.
(6) Layout all the lines that are parallel to the edge resting on surface plate.
