Power planes are used primarily because they offer significant advantages in terms of speed and efficiency when removing material from wood surfaces.
Here's a breakdown of the reasons:
-
Speed: A power plane can remove material much faster than manual planing. This is especially beneficial for large projects or when dealing with a significant amount of wood that needs to be flattened or smoothed. As the referenced text states, power planes can "remove material quickly, making them ideal for larger projects where time is a factor." They can plane large surfaces in a fraction of the time it would take with a bench plane.
-
Efficiency: Power planes provide a consistent and even cut across the wood surface. This reduces the effort required to achieve a desired finish compared to hand planing, where maintaining consistent pressure and angle is crucial.
-
Larger Projects: For extensive planing tasks, such as leveling a large tabletop or preparing multiple boards, a power plane is significantly more practical and less tiring than a hand plane.
-
Material Removal: Power planes are particularly effective when you need to remove a substantial amount of material quickly. This is useful for tasks like leveling uneven boards or reducing the thickness of a piece of wood.
-
Surface Preparation: While not always the sole tool for achieving a final, glass-smooth surface, a power plane can efficiently prepare a surface for subsequent sanding or finishing. It gets you to a more even starting point quickly.
In summary, a power plane is used when speed, efficiency, and the ability to remove material quickly from larger surfaces are prioritized.
