Sharpening your lathe chisels is essential to ensure clean and precise cuts while turning wood. Using a lathe chisel sharpening jig can help you achieve consistent and accurate sharpening results every time. In this article, we will guide you through the process of making your own lathe chisel sharpening jig.
Step 1: Gathering the materials
Before you begin, make sure you have all the necessary materials. You will need a piece of hardwood or plywood for the base of the jig, as well as some hardwood scraps for making the guides and fences. Additionally, you will need screws, nuts, and washers to assemble the jig.
Step 2: Designing the jig
Next, you need to design the jig. The jig should consist of a base with two guides and fences attached. The chisel will be secured between the guides, allowing you to sharpen it at the correct angle. Consider the size and shape of your lathe chisels when designing the jig to ensure a proper fit.
Step 3: Cutting and shaping the guides and fences
Using the hardwood scraps, cut and shape the guides and fences. The guides should have a V-shape groove that will hold the chisel securely. The fences should be tall enough to provide support and stability during the sharpening process. Make sure the guides and fences are symmetrical and aligned correctly on the base.
Step 4: Assembling the jig
Once you have cut and shaped all the necessary parts, it’s time to assemble the jig. Drill holes in the base for the screws that will hold the guides and fences in place. Attach the guides and fences to the base using screws, nuts, and washers. Ensure everything is tightly secured.
Step 5: Testing and adjusting
After assembling the jig, test it by placing a chisel between the guides and sharpening it. Check if the angle is correct and make any necessary adjustments. You may need to modify the jig to accommodate different sizes and shapes of chisels.
By following these steps, you can create a lathe chisel sharpening jig that will help you achieve consistently sharp chisels for your woodturning projects. Happy sharpening!
What is a Lathe Chisel Sharpening Jig?
A lathe chisel sharpening jig is a tool used by woodturners to achieve a sharp edge on their lathe chisels. It is designed to hold the chisel securely in place while allowing the user to precisely set the angle and position of the chisel in relation to the sharpening wheel.
The sharpening jig typically consists of a base, which is attached to the workbench, and an adjustable platform or arm that holds the chisel. The platform or arm can be moved horizontally or vertically to adjust the angle of the chisel. Some jigs also have additional features such as a guide for setting the bevel angle or a mechanism for holding the chisel at a consistent distance from the wheel.
Using a sharpening jig ensures that the chisel is sharpened consistently and accurately, resulting in better cutting performance and a longer tool life. It allows the user to control the shape and angle of the cutting edge, which is crucial for achieving clean and precise cuts in woodturning projects.
Sharpening a lathe chisel with a jig involves grinding the bevel surface of the chisel against the rotating sharpening wheel. The user can adjust the position and angle of the chisel to achieve the desired cutting edge geometry. This process removes any dull or damaged metal from the chisel and creates a fresh, sharp edge.
A lathe chisel sharpening jig is a valuable tool for anyone involved in woodturning, as it simplifies and streamlines the sharpening process. It allows the user to maintain the optimal performance of their chisels and achieve professional-quality results in their woodworking projects.
Tools and Materials
Before you begin sharpening your lathe chisels, make sure you have the following tools and materials:
- Lathe Chisels: You will need the chisels you want to sharpen. Make sure they are in good condition and free from rust.
- Bench Grinder: A bench grinder is necessary for sharpening the chisels. Make sure it is securely mounted on a stable surface.
- Sharpening Jig: To achieve precise and consistent angles, you will need a sharpening jig. This can be either bought or homemade.
- Tool Rest: A tool rest will provide support for the chisel while sharpening. Ensure it is properly adjusted for stability.
- Safety Gear: Wear safety glasses and gloves to protect your eyes and hands from sparks and debris.
- Marker or Paint: Use a marker or paint to mark the bevel angle on the chisel before sharpening.
- Grit Stones: Use different grit stones (coarse, medium, fine) to achieve the desired level of sharpness.
- Honing Compound: Apply honing compound to the strop or leather wheel for a polished and razor-sharp edge.
- Strop or Leather Wheel: A strop or leather wheel is used for the final touch-up and honing of the chisel edge.
- Flat Surface: Use a flat surface, such as a granite or glass plate, to check the flatness of the chisel.
Having these tools and materials ready will ensure a smooth and effective sharpening process for your lathe chisels.
Essential Tools for Making a Lathe Chisel Sharpening Jig
When it comes to making a lathe chisel sharpening jig, having the right tools is essential. These tools will help you create a jig that is accurate, durable, and easy to use. Here are some essential tools that you will need:

By following these steps, you will have a functional jig that will make sharpening your lathe chisels easier and more precise.
Step 1: Measure and Cut the Wood
Before you start building your lathe chisel sharpening jig, you will need to gather the necessary materials. For this project, you will need a piece of hardwood measuring approximately 12 inches in length, 4 inches in width, and 3/4 inch in thickness. Maple or oak wood are good options for this project.
Once you have the wood, use a tape measure to accurately measure and mark the dimensions on the wood. Double-check your measurements to ensure accuracy.
Next, using a saw, carefully cut the wood according to the marked dimensions. Take your time and make precise cuts to ensure that the pieces fit together properly.
After cutting the main piece, you will also need to cut two smaller pieces for the jig’s sides. These pieces should measure approximately 6 inches in length, 4 inches in width, and 3/4 inch in thickness. Again, measure and mark the dimensions accurately, and then cut the wood pieces.
Once all the wood pieces are cut, use sandpaper or a sanding block to smooth out any rough edges or surfaces. This will create a more polished and professional-looking final product.
Remember to wear safety goggles and protective gloves when working with saws and sandpaper to ensure your safety.
Step 2: Drill Holes for the Chisel Holders
Once you have gathered all the necessary materials and tools, you can start drilling holes for the chisel holders. These holes will hold the chisels securely in place while you sharpen them.
Here are the steps to follow:
1. Mark the Position of the Holes
Using a ruler or tape measure, mark the positions where you want to drill the holes on the base of your sharpening jig. It is typically recommended to leave a few inches of space between each hole to ensure that the chisels do not interfere with each other.
2. Secure the Base
Place the base on a stable work surface and secure it firmly with clamps or a vice to prevent it from moving while you drill the holes.
3. Choose the Right Drill Bit
Select a drill bit that corresponds to the size of the chisel shank. It is important to use the correct size to ensure a snug fit and maximum stability.
4. Drill the Holes
Using a power drill, start drilling at each marked position on the base. Make sure to hold the drill perpendicular to the base surface to ensure straight holes. Apply steady and even pressure while drilling to prevent the bit from wandering or causing the hole to become enlarged.
5. Test the Fit
After drilling the holes, test the fit by inserting a chisel into each hole. The chisel should fit snugly without any wobbling or movement.
6. Repeat for Additional Holes
If you have multiple chisels of different sizes, repeat the previous steps to drill corresponding holes for each chisel.
Once you have drilled all the necessary holes, you can proceed to the next step of building your lathe chisel sharpening jig.
