Essential Tools Needed For Sharpening Wood Lathe Tools

An Overview Of The Necessary Tools For Sharpening Wood Lathe Tools

Sharpening wood lathe tools is an essential skill that every woodturner must learn. But before we dive into the sharpening process, let’s take a look at the tools needed to achieve finely honed tools.

  • Bench grinder
  • Diamond sharpening stone
  • Honing compound
  • Honing jig

Let’s take a closer look at each tool and its function.

Explanation Of The Function Of Each Tool

Bench Grinder

A bench grinder is the most important tool for sharpening wood lathe tools. It is a powerful tool with a coarse grinding wheel that can efficiently remove any chips or nicks from your tools’ edges. A bench grinder can be an investment, but it will save you both time and money in the long run.

Diamond Sharpening Stone

Once you’ve removed all nicks and chips in your tools using a bench grinder, it’s time to hone the edges using a diamond sharpening stone. Diamond sharpening stones are known for their durability and will give you a flat and consistent surface to sharpen your tools with.

Diamond sharpening stones are available in different grits and are ideal for honing chisels, gouges, and other wood lathe tools.

Honing Compound

Honing compound is a polishing compound that is used to achieve razor-sharp edges on your wood lathe tools. It is a mixture of abrasive compounds and oil used on a strop or leather strip to sharpen the edges of your tools.

Honing compound comes in different grits and works best after sharpening with a diamond sharpening stone.

Honing Jig

A honing jig holds the wood lathe tool at a specific angle and ensures a uniform bevel during sharpening. It is essential for consistent and accurate honing of your tools. The honing jig is a time-saving tool and is especially helpful if you are new to woodturning.

Tips On Selecting The Best Quality Tools

When selecting the necessary tools for sharpening wood lathe tools, it’s important to choose the best quality tools possible.

  • Look for a bench grinder with a powerful motor and a high-quality grinding wheel.
  • Choose a diamond sharpening stone with a grit and size that would meet your sharpening needs. The size of sharpening stones vary from small pocket stones to the larger bench stones.
  • Pick a honing compound with a fine grit if you want a highly polished edge, and a coarser grit if you want a more aggressive edge.
  • The honing jig should be adjustable and easy to use for different angles.

With the right tools, sharpening wood lathe tools can be a straightforward process. Ensure that you invest in high-quality tools to achieve finely honed and uniform edges on your wood lathe tools. By doing so, you’ll be ready to take on any woodturning project with confidence and precision.

Understanding The Lathe Tool Anatomy

If you’re an avid wood lathe worker, then understanding the tool’s anatomy is essential to sharpening the blades correctly.

  • The cutting edge: This is the part of the tool that comes into contact with the wood and is responsible for cutting the material. This edge needs to be sharpened regularly to ensure its effectiveness.
  • The bevel: The bevel is the flat surface directly behind the cutting line. This area needs to be flat for smooth cuts and should match the angle of the cutting edge.
  • The flute: The flute is the decorative or chamfered part of the tool, often used to create concave shapes in the wood.

Explanation Of The Crucial Parts That Need Sharpening

Now that you understand the anatomy of the lathe tools let’s take a look at the vital parts that need sharpening before using them on the wood:

  • The cutting edge: It’s vital to keep the cutting edge sharp as that will affect the quality of the cut. If this edge is dull or damaged, you will not be able to make precise cuts.
  • The bevel: Keeping the bevel flat is also crucial because it makes the tool cut smoothly and ensures consistency with the angle of the cutting edge.

Importance Of Inspecting Your Lathe Tools Before Sharpening

Before you start sharpening, it’s essential to inspect the lathe tools to ensure you’re sharpening the right parts.

  • Clean the tool: Use a wire brush or a scraper to remove any debris from the tool. This cleaning exercise will allow you to see any damages that may need fixing before sharpening.

-inspect the tool for damages: inspect the tool for any damages, like cracks or chips, as sharpening it in this state can damage it even further. Replace and repair any damaged tools before sharpening.

-ensure the tool is sharpened at the correct angle: make sure the angle of the cutting edge matches the bevel, and they’re both sharpened correctly.

Understanding the anatomy of the lathe tool, the crucial parts that need sharpening, and inspecting the tool before sharpening, are essential steps when sharpening wood lathe tools. Remember to keep the cutting edge sharp and bevel flat to enhance the tool’s smoothness and consistency, and keep the tools clean and free from any damages before sharpening.

Step By Step Guide On How To Sharpen Wood Lathe Tools

Preparing Your Lathe Tools For Sharpening

Before sharpening your lathe tools, it’s essential to prepare them properly to ensure you get the best results.

  • Wear eye protection to avoid injury from flying debris
  • Remove any rust or debris from the tool using sandpaper or a wire brush
  • Make sure the tool is secure in your lathe by tightening the clamp
  • Position the tool rest parallel and close to the workpiece
  • Turn off the lathe and unplug it before sharpening

Sharpening The Different Types Of Lathe Tools

Different types of lathe tools require different approaches when it comes to sharpening.


  • Position the tool handle slightly below center to ensure proper cutting angle
  • Keep the gouge flat on the tool rest and rotate it into the grinding wheel
  • Move the gouge back and forth on the grinding wheel to sharpen evenly


  • Use a diamond hone or sharpening stone to sharpen the cutting edge
  • Hold the scraper flat against the stone and move it in a circular motion

Parting Tools

  • Use a grinder with a fine grit wheel to sharpen the cutting edge
  • Position the tool handle slightly above center to achieve the correct angle
  • Move the tool back and forth across the grinding wheel to avoid overheating

Achieving The Correct Angle And Maintaining It

Achieving the correct angle is critical when it comes to sharpening lathe tools. Failing to achieve the correct angle can impact the overall quality of your work.

  • Use a protractor or angle finder to measure the angle
  • Hold the tool flat on the tool rest and rotate it into the grinding wheel to achieve the desired angle
  • Once the correct angle is achieved, maintain it by keeping the tool flat on the tool rest throughout the sharpening process

Honing The Tool For The Perfect Finish

Honing is the final step in sharpening your lathe tools and can make a big difference in the quality of your work.

  • Use a honing compound to refine the cutting edge
  • Apply the honing compound to the leather strop and rub the tool back and forth to polish the cutting edge
  • Avoid applying too much pressure when honing to prevent damage to the cutting edge

Tips For Avoiding Common Sharpening Mistakes

Sharpening lathe tools requires practice and patience.

  • Overheating the tool during sharpening, which can ruin the temper and hardness of the steel
  • Neglecting to flatten the back of the tool before sharpening
  • Grinding the tool at the wrong angle
  • Failing to maintain a consistent angle while sharpening

By following this step-by-step guide, you can be confident in your ability to sharpen your lathe tools effectively and efficiently, leading to better quality work and a more enjoyable experience overall.
