After the block is planed true and to the correct dimensions, lay out the lines across the face at the left hand end shown in the drawing and square the lines down the depth on the edges; then set the gauge and mark around the end and notch on both edges. Beginners will find it a little difficult at first to saw a perfectly clean line so as to secure a sharp corner; by cutting notches with a knife point as shown at [Fig. 53], it will be easy to secure sharp corners. Place the back-saw, [Fig. 54], in the notch, hold it tightly against the flat side, and saw down to the desired depth, removing the portion from the end with the rip saw ([see Fig. 55]).
