Choosing the right wood is important if you would be using a wood jointer. The type of wood you use will affect the quality of the jointer's performance and the final result of your project. Different wood species have varying degrees of hardness, density, and grain pattern. Hardwoods like oak and walnut are durable and suitable for heavy-duty jointing tasks. Softwoods like pine and fir are more affordable and work well for lighter jointing jobs.

It's crucial to consider the characteristics of the wood and match it to your specific project requirements. Doing so will ensure better results and a smoother woodworking experience.

Inspecting the Wood for Imperfections

Inspecting the wood for imperfections before running the wood through the jointer is essential. 

Look for knots, cracks or any other defects that could affect the quality of the joint. These 

flaws can cause tear-out or compromise the strength of the joint. For example, a knot in the 

wood could lead to a weakened connection. By thoroughly inspecting the wood beforehand, 

you can avoid potential issues and ensure a smooth, strong joint.

Always take the time to closely examine the wood and address any imperfections before proceeding.

Using the Wood Jointer

Setting Up the Wood Jointer

  • Start by checking that the jointer is placed on a stable and level surface for accurate results.
  • Adjust the infeed and outfeed tables so they are coplanar, which means they are perfectly aligned with each other.
  • Set the depth of cut by lowering the cutter head to the desired depth; make sure to use the appropriate safety measures.
  • Align the fence to ensure it is perpendicular to the table, allowing for accurate and straight cuts.
  • Check the knife alignment and make any necessary adjustments to ensure they are parallel to the table surface.
  • Always refer to the manufacturer's manual for specific instructions on setting up your particular wood jointer model.

Jointing the First Edge

Jointing the first edge is a fundamental step in using a wood jointer. It involves flattening one 

side of a board to create a reference surface. This surface will be used to create straight and 

square edges on the remaining sides of the board. By jointing the first edge, you establish a 

stable starting point for the rest of the project.

For example, if you're building a table, jointing the first edge ensures that all subsequent edges will align properly, leading to a sturdy and visually appealing finished product.

Jointing the Second Edge

Follow these steps to joint the second edge of the wood.

First, make sure the wood is securely placed on the jointer’s bed so it does not shift during the process.

Then, adjust the jointer's fence to the desired angle and depth of cut so it is parallel to the jointed surface.

Next, slowly feed the wood along the jointer, applying consistent pressure to maintain a smooth cut.

Remember to continuously check the jointed edge for any imperfections or inconsistencies and make adjustments as necessary.

By jointing the second edge, you ensure both edges are parallel and ready for further woodworking tasks such as gluing or joining.

Flattening the Face

Flattening the face is a fundamental task when using a wood jointer. It involves levelling the 

surface of a rough piece of wood to create a smooth and even face.

This step is important because it provides a stable foundation for further woodworking processes.

Without a flat face, it is difficult to achieve precise measurements and joinery. To accomplish this, the woodworker feeds the wood across the jointer's blades, removing uneven areas until the desired flatness is achieved. Regularly checking for flatness ensures accurate and consistent results in woodworking projects.
