The secret behind the function of a woodworking jointer lies in its component which is power packed to ensure the best possible result.

 A woodworking jointer comprises three main parts namely, 

  • Infeed Table
  • Outfeed Table
  • Cutter Head

These three components are very important parts of a woodworking jointer, you don’t utilize one and neglect the other, they work hand in hand to achieve a goal which is to flatten the surfaces and edges of a board.

The infeed and outfeed tables are flat without any form of a twist.

The infeed table was lowered in such a way as to accommodate the cutter head which is a dead flush.

Furthermore, the desired boards are placed on the cutter head in the infeed table, with every inch of movement, the undesired excesses of the board are cupped out removing champs, this way, the board becomes parallel with the outfeed table indicating a flat result.

Kindly note, you can adjust the depth to which you want the board cut by lowering or raising the infeed table to suit your objective.

Most projects require a depth of cut of around 1/16 to 1/8 inch, which is why jointers come in a variety of sizes. The most common jointer is a 6-inch jointer, which means the cutter head is 6 inches long, restricting the maximum board width the machine can accommodate.

The length of the infeed and outfeed tables, known as the bed, also varies; the longer the bed, the wider the reference area and the longer the boards that may be processed by the jointer. A jointer can often handle boards up to twice the length of its bed.

Choosing between a jointer and a planer

Jointers and planers are two distinct tools that are frequently used in tandem. Most woodworkers will agree that a jointer and planer are required to get the most out of your raw material. There are additional jointer-planer combos available.

A jointer can flatten and square a board, but it cannot mill a board to a regular thickness or mill it to precise specifications. While a jointer may be used to flatten both faces or all four sides of a piece, this generally results in a tapered board or one that is thicker on one end than the other. A jointer can generate flat edges, but it is not intended to maintain opposing sides parallel.

A planer, often known as a thickness planer, is a thicknesser: It cuts a board to a uniform thickness throughout its length, resulting in a flawlessly flat surface on both sides. A board should have one flat side with a square edge before going through the planer, which is where the jointer comes in. After being joined, the board is passed through the planer with its flat side against the planer bed. The planer then slices the board’s rough top surface, making the second face parallel to the first.
