3. |
Firmly clamp the workpiece between the timber dogs of the carpenter’s bench with one wide face on top. |
Working direction ad grain direction of workpiece to be
considered. |

|
7. |
Check the face for flatness and smoothness. |
Check the fase in longitudinal and cross directions with straightedge and visually and touch it with the hand. |
| | |
