Jointers?

Jointers are essential woodworking tools used to flatten and straighten the edges and faces of boards. They play a crucial role in preparing lumber for various woodworking projects by creating flat, even surfaces and edges that allow for accurate and tight joinery.
A jointer typically consists of a flat infeed table, a flat outfeed table, and a set of cutting knives mounted on a cylindrical cutter head located between the two tables. The infeed table is adjustable in height, allowing for the removal of varying amounts of material during the jointing process. The outfeed table, which is level with the cutting knives, supports the wood as it exits the jointer, ensuring a smooth and flat surface.
To use a jointer, a woodworker feeds the lumber across the infeed table and over the cutting knives. As the wood passes over the knives, they remove a thin layer of material, flattening the surface or edge. The flattened wood then continues onto the outfeed table, resulting in a straight and even piece of lumber.
Jointers are commonly used for:

1. Flattening the face of a board: This ensures that one side of the board is flat and smooth, providing a reference surface for further milling processes, such as planing or ripping on a table saw.
   
2. Straightening and squaring the edge of a board: Jointers can be used to create straight and square edges, which are crucial for creating tight and accurate joints in woodworking projects.
   
3. Removing twists, warps, or bows: Jointers can also help correct lumber defects, such as twists, warps, or bows, by removing material until a flat and even surface is achieved.
   

In summary, jointers are indispensable woodworking tools that help prepare lumber for various projects by creating flat, straight, and square surfaces and edges. Their proper use ensures that woodworkers can achieve precise and accurate joinery, resulting in high-quality woodworking projects.


Lumber Wizard metal detectors are used in woodworking to locate nails, screws, and other metal objects that may be hidden in the wood. These objects can damage saw blades and other cutting tools, so it is important to locate them before beginning any woodworking project.

When using a jointer with a Lumber Wizard metal detector, the metal detector is first turned on and passed over the surface of the wood to be jointed. The metal detector emits an audible alert or a visual signal when it detects a metal object, allowing the woodworker to mark the location of the object on the board.

Once all metal objects have been located and marked, the jointer can be used to flatten and straighten the edges of the board. The woodworker should take care to avoid cutting through or damaging any metal objects that have been located by the metal detector.

After the jointing process is complete, the board can be checked again with the metal detector to ensure that all metal objects have been removed or avoided. This can help to prevent damage to cutting tools and ensure that the finished product is of high quality.
