A jointer or in some configurations, a jointer-planer (also known in the uk and australia as a planer or surface planer, and sometimes also as a buzzer or flat top) is a woodworking machine used to produce a flat surface along a board’s length.
What Does a Jointer Do?
A jointer is a woodworking tool used to create flat, even surfaces on a workpiece. A jointer can also be used to create angled or beveled edges on a workpiece.
Most jointers have a rectangular table with a blade mounted in the center of the table. The table is raised and lowered to adjust the depth of cut.
The workpiece is fed into the blade, which cuts a thin strip of wood from the surface of the workpiece. The blade on a jointer is usually set at a fixed angle, which means that the depth of cut will be the same along the entire length of the blade.
This is important for creating a smooth, even surface on the workpiece. Jointers are typically used to prepare a workpiece for gluing or for finishing.
A well–prepared surface will result in a stronger bond and a better–looking finish. Jointers are also used to create decorative edge treatments on a workpiece.
By cutting a series of shallow grooves into the edge of a workpiece, a jointer can create a raised or lowered edge. This can be used to create a variety of looks, from a simple bead or bead and cove to a more complex ogee or sc
