Why Cut Tapers?
Tapers are more than just decorative. They serve practical purposes in woodworking, affecting stability, aesthetics, and functionality.
Functional Uses of Tapers:
- Furniture Legs: Many table legs, chair legs, and bedposts have tapered ends for a lighter, more elegant look and to prevent them from looking too bulky at the floor.
- Tool Handles: Tapered handles on chisels, hammers, and files provide a comfortable and secure grip.
- Joinery: Tapers are essential in certain joinery techniques, like wedges and tenons, ensuring a tight fit.
- Decorative Elements: From picture frames to architectural trim, tapers can add visual interest and sophistication.
Aesthetic Appeal:
Tapers can dramatically change the visual weight of a piece. A straight, square leg might feel heavy, while a tapered one can feel lighter and more refined.

The Challenge of Cutting Tapers on a Table Saw
Cutting tapers on a table saw isn’t as straightforward as ripping or crosscutting. The standard fence and miter gauge methods don’t lend themselves easily to creating consistent, angled cuts across the face of a board. You can’t simply set the table saw fence to a specific width and expect an angled cut.
This is where specialized jigs and techniques come into play. Trying to freehand taper cuts is dangerous and will yield inconsistent results.
Common Methods for Cutting Tapers
There are several reliable methods for cutting tapers, each with its own advantages. The most effective methods involve using jigs that guide the workpiece at the desired angle relative to the blade.
Method 1: Using a Table Saw Taper Jig
A table saw taper jig is the most recommended and safest way to cut consistent tapers. These jigs provide a stable platform to hold your wood at a fixed angle.
How to Make a Taper Jig:
Creating your own table saw taper jig is a popular and rewarding project.
Materials:
- Plywood (¾ inch thick is ideal for stability)
- Hardwood (for runners or reinforcing)
- Screws
- Wood glue
- Table saw
- Drill
- Jigsaw or bandsaw
- Sander
Steps:
- Design: The basic design involves a base with a fence attached at an angle. The workpiece is clamped to the fence. The jig needs runners that fit precisely into your table saw’s miter slots, ensuring smooth and accurate movement.
- Cut the Base: Cut a piece of ¾-inch plywood to your desired size. A common size is around 8 inches by 24 inches. This provides ample surface area.
- Create Runners: Cut two strips of hardwood or ¾-inch plywood slightly narrower than the width of your table saw’s miter slots. These will be glued and screwed to the underside of the jig base. Ensure they are parallel and the correct width for a snug fit.
- Cut the Fence: Cut another piece of ¾-inch plywood for the fence. This piece will be attached to the base at an angle.
- Determine the Angle:
- Marking the Taper: Lay your workpiece on the base of the jig. Mark the start and end points of your taper on the workpiece.
- Aligning the Fence: Position the fence piece against the edge of your workpiece, aligning it with your taper marks. You can use a protractor or a table saw fence jig designed for angle setting to help. Alternatively, you can create a jig with adjustable angles.
- Pre-drilling and Attaching: Once aligned, pre-drill through the base and into the fence, then secure the fence with screws and wood glue. Ensure the screws don’t interfere with the blade path.
- Refine and Test:
- Smooth Edges: Sand all edges to prevent snags.
- Test Cuts: Make a test cut on scrap wood to ensure the angle is correct and the jig moves smoothly. You might need to adjust the fence angle slightly.
Using a Table Saw Taper Jig:
- Attach the Jig: Slide the runners of your completed table saw taper jig into the miter slots of your table saw.
- Secure the Workpiece: Place your lumber onto the jig’s fence. Use clamps to firmly secure the workpiece to the fence. Ensure the clamps are positioned so they won’t interfere with the blade or the jig’s movement.
- Set the Blade Height: Adjust the table saw blade so its top edge is slightly higher than the workpiece. This is crucial for a clean cut.
- Set the Table Saw Bevel (if applicable): For standard tapers cut with a jig, the blade is usually kept at 90 degrees (no bevel). The angle is created by the jig itself. If you are doing a more complex cut where the angle is achieved through a combination of jig angle and blade bevel, you would adjust the setting table saw bevel accordingly. However, for most tapers, the blade remains vertical.
- Make the Cut: Push the jig with the secured workpiece through the blade. Maintain steady pressure and keep the jig against the miter slots.
- Repeat: For symmetrical tapers on the opposite side of the workpiece, you will typically flip the jig and workpiece over or reposition the workpiece against the fence.
Method 2: Using the Table Saw Fence with a Push Block/Sticking
This method is generally less recommended due to safety concerns, especially for longer tapers or when cutting freehand. It involves using the table saw fence as a guide.
Steps:
- Set the Blade Tilt: This is where bevel cutting table saw becomes relevant. You will tilt the table saw blade to the desired taper angle. This is the opposite approach to the taper jig where the blade stays at 90 degrees.
- Adjust Blade Height: Set the blade height to be just above the workpiece.
- Position the Fence: The fence is set to a specific distance from the blade, but this distance changes as the wood moves through the blade, creating the taper. This is where it gets tricky and requires precise calculation or a reference point.
- Use a Push Block: A push block or push stick is essential to keep your hands away from the blade. The workpiece is held against the fence and the table, and the entire assembly is pushed through the blade.
- Cutting Angles Table Saw: This method relies on setting the cutting angles table saw directly by tilting the blade. The accuracy depends heavily on how well you can maintain the wood against both the fence and the table throughout the cut.
Safety Note: This method carries a higher risk of kickback. It’s crucial to maintain constant, firm contact between the wood, the fence, and the table. A table saw sled for angles could be adapted for this, but a dedicated taper jig is generally safer and more precise.
Method 3: Adapting a Table Saw Sled for Angles
A standard table saw sled for angles can be modified or used in conjunction with other guides to cut tapers.
Steps:
- Standard Sled: A sled typically has a fence that runs parallel to the blade. To cut a taper, you would need to modify the sled’s fence or use an auxiliary fence attached at an angle.
- Angle Attachment: You could create an angled cleat that attaches to the sled’s fence at the desired taper angle.
- Clamping: Secure the workpiece to this angled cleat.
- Cutting: Slide the sled through the blade as usual.
This method combines the stability of a sled with the angled guide needed for tapers. It’s a good intermediate approach if you don’t have a dedicated taper jig.
Method 4: Using a Table Saw Fence Jig for Tapering Wood with Power Tools
A dedicated table saw fence jig can be designed specifically for cutting tapers. These often involve a sliding component that allows you to adjust the angle of the cut without tilting the blade.
Design Principles:
- Sliding Fence: A fence that can pivot or slide at a specific point allows for precise angle adjustment.
- Adjustable Angle Stop: A mechanism to lock the fence at a chosen angle.
- Workpiece Clamp: Essential for securing the material.
This type of jig offers excellent control and repeatability. It’s a more advanced jig but highly effective for tapering wood with power tools.
Key Considerations for Accurate Taper Cuts
Achieving precise and consistent tapers requires attention to detail and proper technique.
The Importance of a Sharp Blade:
A dull blade will tear the wood, leading to rough edges and inaccurate tapers. Ensure your blade is sharp and has the correct tooth count for the type of wood you are cutting.
Blade Height and Kerf:
- Blade Height: The blade should extend only slightly above the workpiece (about ⅛ to ¼ inch). Too much blade exposure increases the risk of kickback.
- Kerf: Consider the width of the cut (kerf) made by your blade. When using jigs, the kerf is usually accounted for in the jig’s design. If you’re cutting on the waste side of your line, the kerf is less critical.
Consistent Push and Support:
Maintain even pressure on your jig or workpiece throughout the cut. Ensure the jig or workpiece remains firmly against the miter slots or fence.
Repetitive Tapers:
When cutting tapers on multiple pieces, consistency is key.
- Marking: Clearly mark each piece.
- Jig Accuracy: Ensure your jig is securely set.
- Workpiece Placement: Clamp the workpiece in the exact same position on the jig each time.
Setting Table Saw Bevel vs. Jig Angle:
This is a critical distinction.
- Jig Method: The blade is at 90 degrees. The angle is achieved by the jig. This is generally safer as the blade is not tilted.
- Blade Tilt Method: The blade is tilted to the desired angle. The fence is set at a fixed distance. This requires extreme care to maintain contact and avoid kickback.
Understanding Cutting Angles Table Saw:
When using a jig, you are essentially setting the angle of the workpiece relative to the blade. When tilting the blade, you are setting the blade’s angle relative to the table. Both achieve a taper, but the former is usually preferred for safety and ease of use.
Safety First!
Working with table saws always demands respect and adherence to safety protocols.
Kickback Prevention:
- Never force the cut. Let the blade do the work.
- Use push sticks and push blocks. Keep your hands away from the blade.
- Ensure the wood is supported. It should be held firmly against the table and the fence/jig.
- Avoid cutting small pieces without appropriate jigs. Small offcuts are prone to kickback.
- Check that the blade is sharp and the table saw is properly set up.
Maintain Clear Workspace:
Keep your work area clean and free of clutter. Ensure good lighting.
No Bevel Cutting Table Saw Without Proper Guides:
If you choose to tilt the blade for tapers, always use a reliable method to guide the wood, such as a specialized sled or jig. Never attempt to freehand a tapered cut with a tilted blade.
Frequently Asked Questions (FAQ)
Q1: Can I cut a taper on a table saw without a jig?
While technically possible, it is strongly discouraged due to significant safety risks. Freehand cutting tapers with a table saw, especially by tilting the blade, greatly increases the chance of kickback and serious injury. Always use a jig for safe and accurate taper cuts.
Q2: How do I calculate the angle for a taper?
If you know the desired reduction in width over a certain length, you can use trigonometry. For example, if you want to reduce a 2-inch board by 1 inch over 12 inches of length, you’re looking for an angle where the tangent is (1 inch reduction / 12 inches length) = 0.0833. The arctan of 0.0833 will give you the angle. Most taper jigs allow you to set this by physically aligning the jig’s fence with your marked taper on scrap wood.
Q3: What is the best type of table saw taper jig?
The “best” jig often depends on your needs. A simple shop-made jig is excellent for occasional use. For frequent or critical taper cutting, a commercial jig or a well-engineered shop-made jig with adjustable angles and robust clamping mechanisms is ideal.
Q4: How do I ensure the taper is consistent on all sides of a piece?
For tapers on multiple sides of a single piece (like a table leg), you typically need to reposition the workpiece on the jig or use a jig that allows for different clamping orientations. For example, to taper both edges of a board, you’ll likely cut one taper, then reposition the board on the jig to cut the second taper.
Q5: Can I use a table saw sled for angles to cut tapers?
Yes, a table saw sled for angles can be adapted. You would typically attach an auxiliary fence to the sled at the desired taper angle and then clamp your workpiece to this angled fence. This provides the stability of a sled with the required angle for tapering.
