Overview of jointer
A jointer is a woodworking tool that is used to create flat and straight surfaces on a piece of timber. It is an essential tool in any woodworking shop, as it allows for precise trimming and shaping of lumber.
The jointer consists of a long, flat table that is typically made of cast iron. This table is fitted with an adjustable fence, which helps to guide the timber as it is passed through the machine. The cutter head is located beneath the table and is equipped with sharp knives or blades that remove material from the surface of the wood.
When using a jointer, the timber is fed into the machine with the grain running perpendicular to the fence. This ensures that the cutter head removes any imperfections and creates a flat surface. The adjustable fence can be set at different angles, allowing for bevel cuts or chamfers.
There are several key steps to using a jointer effectively. First, the timber must be properly prepared by ensuring that it has at least one flat and straight edge. This edge is then placed against the fence, and the timber is fed through the machine, taking light cuts each time. The process is repeated until the desired surface is achieved.
It is important to note that the jointer is a powerful tool and should be used with caution. Safety precautions, such as wearing protective eyewear and using push blocks or sticks, should always be followed. Additionally, proper maintenance and sharpening of the blades are necessary to ensure optimal performance.

Preparing the timber
Before you begin using a jointer to make your timber straight, it’s important to properly prepare the wood. Follow these steps to ensure optimal results:
1. Select the right lumber
Choose a piece of timber that is suitable for your project. It should be free from knots, cracks, and other defects. The wood should also be dry and stable, as wet or unstable wood can lead to uneven results.
2. Measure and mark
Measure and mark the areas on the timber that need to be straightened. This will give you a clear visual reference and help you to maintain consistency throughout the process.
3. Remove any obstacles
Before running the timber through the jointer, ensure that there are no nails, staples, or other metallic objects embedded in the wood. These can damage the jointer’s blades and potentially cause accidents.
4. Ensure safety
Prior to using the jointer, make sure you are wearing appropriate safety gear such as safety glasses and ear protection. Keep loose clothing and long hair secured to prevent accidents.
5. Set the jointer correctly
Adjust the jointer’s blade height and fence position to match the desired depth and angle of cut. Refer to the manufacturer’s instructions for specific guidance, as different jointers may have varying adjustment mechanisms.
By following these steps, you will ensure that your timber is well-prepared for the jointer, resulting in a straight and smooth finish.
Operating the jointer
Operating a jointer properly is essential for achieving straight timber. Here are some steps to follow:
1. Safety precautions
Before operating the jointer, make sure you are wearing appropriate safety gear, such as safety glasses and ear protection. Ensure that the jointer is securely grounded and that there are no loose or damaged parts. Keep your hands away from the cutterhead and never wear loose clothing or jewelry that could get caught in the machine.
2. Adjusting the fence
Start by adjusting the fence on the jointer. The fence should be set at a 90-degree angle to the table and parallel to the cutterhead. Use a square to check the alignment of the fence and make any necessary adjustments.
3. Setting the depth of cut
Next, set the depth of cut on the jointer. The depth of cut determines how much material will be removed with each pass. Start with a shallow depth of cut and gradually increase it until you achieve the desired results. Avoid taking off too much material at once, as this can lead to uneven surfaces.
4. Feeding the timber
Feed the timber into the jointer with a smooth and steady motion. Make sure the timber is flat against the table and against the fence. Keep your hands on the timber, but be cautious not to apply too much pressure, as this can cause the timber to bow or twist.
5. Inspecting the result
After each pass, inspect the result to ensure the timber is getting straightened. Look for any inconsistencies or rough spots and make any necessary adjustments. If you notice any issues, repeat the process, making slight adjustments as needed.
