How to tune a jointer plane
A jointer plane is an essential tool for woodworkers who want to create flat surfaces on their workpieces. It helps to straighten and smooth rough lumber, ensuring that the final project is both accurate and professional-looking. However, like any other tool, a jointer plane needs to be properly tuned to work at its best.
When tuning a jointer plane, there are several key steps to follow. First, you need to check the sole of the plane for any high spots or irregularities. Use a straightedge to ensure that the sole is flat and adjust it if necessary. Next, you should focus on the blade. Sharpen it properly, ensuring that it has a smooth and even cutting edge. Additionally, make sure that the blade is properly aligned with the plane’s body to achieve optimal performance.
Another important aspect of tuning a jointer plane is setting the mouth opening. The mouth opening refers to the gap between the blade and the front of the plane’s body. Adjusting the mouth opening can significantly affect the plane’s performance. A smaller opening allows for finer shaving, perfect for smoothing out surfaces, while a wider opening is better for rough work. Experiment with different mouth settings to find the one that suits your needs best.
Lastly, it is crucial to pay attention to the adjustment screws and knobs on the jointer plane. These control the depth and lateral position of the blade. Make sure they move freely and are easy to adjust. If necessary, lubricate the screws and knobs to ensure smooth operation. Also, consider investing in a reliable plane stop to prevent accidental movement of the blade during use.
Tuning a jointer plane may require some time and practice, but it is an essential step towards achieving great woodworking results. By following these steps and regularly maintaining your jointer plane, you can ensure that it performs optimally and helps you create exceptional woodworking projects.

Checking the Sole for Flatness
Before starting to tune a jointer plane, it is crucial to check the sole for flatness. The sole of the plane should be perfectly flat to ensure that it will produce accurate and smooth cuts. Here are the steps to check the sole for flatness:
Step 1: Clean the Sole
Begin by cleaning the sole of the jointer plane. Use a cleaning solution or mineral spirits to remove any dirt, rust, or debris that may be present. Wipe the sole clean with a cloth or paper towel.
Step 2: Place on a Flat Surface
Next, find a flat and level surface to place the jointer plane on. This surface could be a granite slab, a glass plate, or any other known flat surface. Ensure that the surface is clean and free from any irregularities.
Step 3: Tap Test
To check the flatness of the sole, gently tap the plane along its length. Listen for any uneven sounds or vibrations. If there are any high spots or low spots on the sole, they will produce a different tapping sound.
Step 4: Visual Inspection
After the tap test, visually inspect the sole for any gaps or inconsistencies. Look for any light passing through between the sole and the flat surface. Gaps or uneven contact points indicate that the sole is not flat and needs to be corrected.
Step 5: Correcting the Sole
If you find any high spots or low spots on the sole, you will need to correct them to achieve flatness. This can be done by using a flat surface like sandpaper on a known flat surface, a jointer, or a hand plane.
By ensuring that the sole of your jointer plane is perfectly flat, you will have a tool that is capable of producing precise and accurate cuts. Take your time to thoroughly check and correct the sole for optimal performance.
Using a Straight Edge and Feeler Gauge
To ensure your jointer plane is properly tuned, you can use a straight edge and a feeler gauge. This method allows you to check the flatness of your plane’s sole and make any necessary adjustments.
Here’s how you can use a straight edge and feeler gauge to tune your jointer plane:
- Place the straight edge across the sole of the plane.
- Inspect for any gaps between the straight edge and the sole. If you notice any gaps, it means your plane’s sole is not flat.
- Use the feeler gauge to measure the size of the gap. This will give you an idea of how much material needs to be removed or adjusted.
- Identify the high spots on the sole by sliding the feeler gauge under the straight edge.
- Use a file or a plane to remove the high spots on the sole. Take your time and make small adjustments to ensure the flatness of the sole.
- Periodically check the flatness of the sole using the straight edge and feeler gauge until you achieve the desired level of flatness.
Using a straight edge and feeler gauge is an effective method for tuning your jointer plane. It allows you to accurately measure the flatness of the sole and make precise adjustments. By following these steps, you can ensure that your jointer plane is working optimally and producing quality results.
Adjusting the Blade Angle
Properly adjusting the blade angle is crucial for achieving accurate and clean cuts with your jointer plane. Here are the steps to adjust the blade angle:
- Start by loosening the lever cap screw on your jointer plane to release the blade.
- Use a square or angle measuring tool to ensure that the blade is perpendicular to the sole of the plane. Adjust the blade by tapping it gently with a hammer until it is perfectly square.
- Tighten the lever cap screw to secure the blade in place.
- Next, adjust the depth of cut by loosening the depth adjustment screw. Gradually lower the blade until it just barely touches the surface of the wood.
- Once the desired depth of cut is achieved, tighten the depth adjustment screw to lock the blade in place.
It is important to check the blade angle and depth of cut after every few passes to ensure that it remains accurate. Making small adjustments as needed will result in smoother and more precise cuts.
Remember to always wear safety goggles and work on a stable work surface when using a jointer plane. Take your time and practice using the plane on scrap wood before moving on to your actual project to avoid any mistakes.
Using a Bevel Gauge and Tapping Block
One of the key tools you’ll need when tuning a jointer plane is a bevel gauge. A bevel gauge allows you to accurately measure the angle of the blade in your plane. This is important because the angle of the blade will determine how the plane cuts and how the wood is finished.
To use a bevel gauge, start by loosening the blade adjustment knob on your jointer plane. Then place the bevel gauge on the plane’s sole, with the blade resting against the gauge’s face. Adjust the bevel gauge until the blade rests snugly against it, and tighten the adjustment knob to hold the blade in place.
Once the blade is secured, use a tapping block to adjust the depth of cut. A tapping block is a wooden or plastic block that you can tap against the blade to raise or lower it in the plane. Start by tapping lightly on the block to raise the blade slightly above the sole of the plane. Then, using your bevel gauge as a reference, tap the block again to lower the blade to the desired angle.
Checking the Angle
After adjusting the blade, it’s important to check the angle using your bevel gauge. Place the gauge against the blade and make sure it rests flush against both the blade and the sole of the plane. If there’s any gap, adjust the blade using the tapping block until the bevel gauge sits flush against both surfaces.
Fine-Tuning
Once you’ve set the blade angle, you can fine-tune the cutting depth by adjusting the blade using the adjustment knob on the jointer plane. Gradually tighten or loosen the knob to raise or lower the blade until you achieve the desired depth of cut. It may take some trial and error to get the perfect setting, so don’t be afraid to make small adjustments as needed.
By using a bevel gauge and tapping block, you can ensure that your jointer plane is properly tuned for optimal performance. With practice and patience, you’ll be able to achieve smooth and precise cuts with your jointer plane.
Setting the Blade Depth
One of the key steps in tuning a jointer plane is setting the blade depth. This determines the amount of material that will be removed with each pass of the plane. Here’s how to set the blade depth correctly:
1. Prepare the plane
Before setting the blade depth, make sure your jointer plane is properly assembled and adjusted. Ensure that the plane’s mouth is open enough for shavings to pass through without clogging, and that the chipbreaker is properly aligned with the cutting edge of the blade.
2. Loosen the blade adjuster
Locate the blade adjuster knob or screw on your jointer plane. Loosen it to allow for blade adjustment. Be careful not to loosen it too much, as this can result in the blade moving out of position.
3. Set the desired depth
Begin by setting the blade depth to a conservative level. This means having the blade protrude just slightly from the plane’s sole. As you gain experience and confidence, you can increase the depth to remove more material per pass.
Use a depth gauge or a reliable reference surface to measure the blade’s protrusion accurately. Adjust the blade by turning the adjuster knob or screw clockwise to increase the depth or counterclockwise to decrease it.
4. Check for even shavings
Once you’ve set the desired blade depth, make a few passes on a test piece of wood. Check the shavings to ensure they are even and consistent across the entire width of the blade. If the shavings are too thick in the middle or at the edges, adjust the blade depth accordingly until you achieve consistent shavings.
Remember to make small adjustments to the blade depth and test it regularly as you fine-tune your jointer plane. Practice and experience will help you find the optimal blade depth for different types of wood and cutting tasks.
