The plough (plow USA) plane creates channel grooves by removing material from the middle of a piece of wood, leaving two outside edges. The plane has a guide or fence, which runs along the underside or outer edge of the plane body to keep the groove parallel and the plane fully aligned to the material. This fence can be adjusted to change the distance of the groove in relation to the edge of the board.
The plough plane is used to create grooves parallel to an edge, this is useful in creating projects such as window sashes, frames for door construction, tongue and groove floorboards etc. Grooves are used in drawer construction as well as a wide variety of other frame and panel construction projects. The plough plane can be used to reliably create uniform grooves in different widths of cut.
Cutting Irons- High grade carbon steel cutting blades, they come in different width sizes, often in both metric and imperial measurements
Fence- This is a metal or wooden guide that runs along the long axis of the main body of the plough plane and ensures that the groove is a consistent distance from the edge
Depth Stop- This is a guide stop that prevents the plough plane from cutting beyond a predetermined level, ensuring a consistent depth to the groove
Stems- Can come in multiple sizes, the bars which join the two parts of the plane
Lever Cap- Holds the blade in place by pushing the knurled lever cap screw on the top of the blade
