jack plane

Thân thiện

A carpenter uses a jack plane to smooth the edge of a wooden board.

Definition

Noun: A jack plane is a medium-sized, general-purpose carpenter's hand plane used primarily for the initial, rough shaping and flattening of wood. It prepares the surface for finer planes by removing material quickly.

Usage

The term jack plane is used to refer to the specific tool itself. It is a compound noun where "jack" implies a general-purpose or utility role. * The carpenter used a jack plane to remove the high spots from the old timber. * After sawing the board, the first step is to smooth it with a jack plane.

Advanced Usage

• In woodworking terminology, the jack plane is often considered the workhorse of bench planes, typically around 14 to 15 inches long. It bridges the gap between a longer fore plane (for flattening) and a shorter smoothing plane (for final finish).
