Tips for Sharpening a Bench Plane

Use a lubricant, such as honing oil, when sharpening the blade. This will help to prevent the blade from overheating.
Sharpen the blade in a consistent direction. This will help to create a burr on the edge of the blade.
Be careful not to over-sharpen the blade. A too-sharp blade can be dangerous.

How to Sharpen a Bench Plane?

A bench plane is a woodworking tool used to smooth and shape wood. It is essential for any woodworker to know how to sharpen their bench plane properly, as a dull plane will not produce good results.

This guide will show you how to sharpen a bench plane using a sharpening stone. We will cover everything you need to know, from choosing the right stone to maintaining the angle of the blade.

Choosing the Right Sharpening Stone

The first step is to choose the right sharpening stone. There are two main types of sharpening stones: water stones and oil stones.

Water stones are made of a natural abrasive, such as silicon carbide or aluminum oxide. They are soaked in water before use, and the water helps to lubricate the stone and carry away swarf (metal filings). Water stones are typically used for coarse and medium sharpening.
Oil stones are made of a synthetic abrasive, such as diamond or CBN (cubic boron nitride). They do not require water, and the oil helps to lubricate the stone and prevent it from clogging. Oil stones are typically used for fine and ultra-fine sharpening.

The grit size of a sharpening stone refers to the size of the abrasive particles. The higher the grit number, the finer the stone. For a bench plane, you will need a range of grits, from coarse to fine. A coarse stone is used to remove large amounts of material, a medium stone is used to refine the bevel, and a fine stone is used to create a polished edge.

Preparing the Sharpening Stone

Before you can use a sharpening stone, you need to prepare it. This involves wetting the stone and applying honing oil.

Wetting the stone. To wet the stone, simply soak it in water for a few minutes. The water will help to lubricate the stone and carry away swarf.
Applying honing oil. Honing oil is a special oil that is used to lubricate the stone and prevent it from clogging. Apply a few drops of oil to the stone and then spread it around with your finger.

Maintaining the Angle of the Blade

The most important part of sharpening a bench plane is maintaining the correct angle of the blade. The angle of the blade is the angle at which it meets the stone. The correct angle for a bench plane is typically around 25 degrees.

To maintain the angle of the blade, you can use a sharpening guide. A sharpening guide is a tool that helps you to keep the blade at the correct angle. You can also use a machinist’s square to check the angle of the blade.

Sharpening the Blade

Now that you have prepared the sharpening stone and maintained the angle of the blade, you can start sharpening the blade.

To sharpen the blade, simply draw the blade across the stone in a back-and-forth motion. The direction of the stroke should be away from you. As you sharpen the blade, the swarf will start to accumulate on the stone. You should periodically wipe the swarf off the stone with a cloth.

Continue sharpening the blade until you have created a burr on the edge of the blade. A burr is a small ridge of metal that forms on the edge of the blade. You can check for a burr by running your finger along the edge of the blade. If you feel a sharp edge, then you have created a burr.

Honing the Blade

Once you have created a burr on the edge of the blade, you need to hone the blade. Honing is the process of removing the burr and creating a polished edge.

To hone the blade, simply draw the blade across the stone in a back-and-forth motion. The direction of the stroke should be towards you. Honing the blade will remove the burr and create a polished edge.

Continue honing the blade until you have a sharp, polished edge. You can check the sharpness of the blade by shaving a piece of paper. If the blade shaves the paper cleanly, then it is sharp.

Sharpening a bench plane is a skill that takes practice. However, by following these steps, you can learn how to sharpen your bench plane properly and get the best results from your woodworking projects.

Additional Tips

Here are a few additional tips for sharpening a bench plane:

Use light pressure when sharpening the blade. Too much pressure will cause the blade to dig into the stone and create a concave bevel.
Sharpen the blade in small increments. Don’t try to sharpen the entire blade in one session. Instead, sharpen the blade a little bit at a time, until you have a sharp edge.
Keep the blade clean and free of oil and swa

3. Sharpening the Plane Blade

The plane blade is the most important part of a bench plane. A sharp blade will make your work easier and more enjoyable. A dull blade will make your work more difficult and frustrating.

There are a few different ways to sharpen a plane blade. The most common way is to use a sharpening stone. You can also use a honing guide or a diamond plate.

Establishing the Primary Bevel

The first step in sharpening a plane blade is to establish the primary bevel. The primary bevel is the angle at which the blade meets the wood. The most common primary bevel angle is 25 degrees.

To establish the primary bevel, you will need a sharpening stone and a honing guide. The honing guide will help you to maintain a consistent angle as you sharpen the blade.

Start by placing the blade in the honing guide. The blade should be flat against the guide and the bevel should be facing up.

Dip the sharpening stone in water and then rub it across the bevel of the blade. Make sure to use a light touch. You do not want to apply too much pressure or you will damage the blade.

Rub the stone across the bevel in a back-and-forth motion. Continue sharpening until the bevel is smooth and shiny.

Honing the Secondary Bevel

The secondary bevel is the angle at which the blade meets the sharpening stone. The secondary bevel is usually slightly smaller than the primary bevel.

To hone the secondary bevel, you will need to use a finer sharpening stone than you used to establish the primary bevel.

Start by placing the blade in the honing guide. The blade should be flat against the guide and the secondary bevel should be facing up.

Dip the sharpening stone in water and then rub it across the secondary bevel of the blade. Make sure to use a light touch. You do not want to apply too much pressure or you will damage the blade.

Rub the stone across the secondary bevel in a back-and-forth motion. Continue sharpening until the secondary bevel is smooth and shiny.

Creating a Burr

A burr is a small ridge of metal that forms on the edge of a sharpened blade. A burr helps to keep the blade from slipping when it is cutting wood.

To create a burr, you will need to use a honing guide and a fine sharpening stone.

Start by placing the blade in the honing guide. The blade should be flat against the guide and the bevel should be facing up.

Dip the sharpening stone in water and then rub it across the bevel of the blade. Make sure to use a light touch. You do not want to apply too much pressure or you will damage the blade.

Rub the stone across the bevel in a back-and-forth motion. Continue sharpening until you see a burr form on the edge of the blade.

Stroking the Blade

Once you have created a burr, you need to stroke the blade. Stroking the blade will help to remove the burr and finish the sharpening process.

To stroke the blade, you will need to use a piece of scrap wood.

Place the blade on the scrap wood and stroke it in a back-and-forth motion. Make sure to use a light touch. You do not want to apply too much pressure or you will damage the blade.

Stroke the blade until the burr is gone and the edge of the blade is smooth and shiny.

4. Testing the Blade

Once you have sharpened the blade, you need to test it to make sure it is sharp.

To test the blade, you can use a piece of scrap wood.

Place the blade on the scrap wood and drag it across the grain. The blade should cut through the wood easily without any resistance.

If the blade does not cut through the wood easily, it is not sharp enough. You will need to sharpen it again.

5. Tuning the Blade if Necessary

If the blade is still not sharp enough after you have sharpened it, you may need to tune it.

To tune the blade, you will need to use a lapping plate.

A lapping plate is a flat piece of metal that is used to remove small burrs and imperfections from the edge of a blade.

To tune the blade, you will need to place it on the lapping plate and rub it in a back-and-forth motion. Make sure to use a light touch. You do not want to apply too much pressure or you will damage the blade.

Rub the blade on the lapping plate until it is smooth and shiny.
