How to Sharpen Jointer Blades to Get a Sharper Edge Every Time

Most woodworkers will eventually need to learn how to sharpen jointer blades.

This is not a difficult task, but it does require some practice to get the hang of it. The most important thing to remember is to keep the blades sharp and free of nicks.

A sharp blade will help to prevent tear-out and make for a smoother cut. Nicks can cause the blade to vibrate and produce a less than a smooth surface.

Step by Step Process to Sharpen Jointer Blades

Step 1: Remove the jointer blades from the machine.

To remove the jointer blades from the machine, you first need to remove the blade guard. Once the blade guard is removed, you can access the blades and remove them from the machine.

Step 2: Use a honing stone or sharpening stone to sharpen the blades.

First, find a honing stone or sharpening stone that is appropriate for the blades you are trying to sharpen.

Second, wet the stone with water and then place the blade on the stone at a 20-degree angle. Third, use a back and forth motion to sharpen the blade. Finally, rinse the blade with water and dry it off.

Step 3: Make sure to sharpen both sides of the blades evenly.

When you are sharpening your blades, it is important to make sure that you are sharpening both sides of the blades evenly. This will help to keep your blades in good condition and prevent them from becoming dull.

Step 4: Once the blades are sharpened, reattach them to the machine.

Start by attaching the fence to the jointer. It is important that the fence is at a 90-degree angle to the table.

To check this, use a square or a ruler to measure from the blade to the fence. If it is not at a 90-degree angle, use the adjusting screws on the fence to fix it.

Next, attach the blades to the jointer. Make sure that they are installed in the correct direction and that the teeth are pointing downwards. Use the bolts that come with the jointer to secure the blades in place.

Finally, expand the blades so that they are slightly wider than the width of the jointer. This will ensure that they stay sharp for longer. Use the adjustment knob on the side of the jointer to expand the blades.

Pro Tip: Jointer blades must be kept sharp to produce smooth, flat boards. Sharpen the blades regularly to keep them in good condition.
