We’ll also touch upon advanced techniques like employing a dado blade taper for specific applications and crafting custom table saw jigs.

Why Cut Tapers?

Tapers add visual interest and structural integrity to woodworking projects. Think of the legs of a chair or a table; they often taper towards the bottom for stability and aesthetic appeal. Similarly, tool handles, drawer pulls, and even architectural mouldings can benefit from a tapered design. Cutting tapers accurately requires a consistent angle throughout the cut, and the table saw, with the right setup, is an excellent tool for this job.

Essential Safety First!

Before we dive into the techniques, let’s reiterate the golden rule of woodworking: safety. Always:

Wear safety glasses: Protect your eyes from flying sawdust and debris.
Use hearing protection: Table saws can be loud.
Keep your hands away from the blade: Maintain a safe distance at all times.
Ensure the blade guard is in place: Unless a specific jig or operation necessitates its removal, keep it on.
Use a push stick or push block: Never push small pieces of wood through the blade with your hands.
Unplug the saw when changing blades or making adjustments.
Know your saw: Familiarize yourself with its features and limitations.

Methods for Cutting Tapers on a Table Saw

There are several effective ways to cut a taper on a table saw, each with its advantages. The choice often depends on the size of the workpiece, the desired angle, and the available jigs.

1. Using a Table Saw Taper Jig

A dedicated table saw taper jig is arguably the most popular and straightforward method for cutting tapers. These jigs provide a stable and adjustable platform to guide your workpiece against the blade at a specific angle.

Building Your Own Table Saw Taper Jig

While you can purchase commercial taper jigs, building your own can be a rewarding and cost-effective woodworking experience. Here’s a basic design concept:

Materials:

A sturdy piece of plywood or MDF (e.g., 3/4 inch thick) for the base.
A long, straight piece of wood (e.g., 1×4 or 1×6) for the fence that rides against the table saw’s rip fence.
A way to attach your workpiece securely to the jig (e.g., clamps, screws, or a dedicated holding mechanism).
Hardware for adjustment (e.g., bolts, washers, nuts, or even a T-track system).

Construction Steps:

Create the Base: Cut a piece of plywood or MDF to a suitable size. It should be large enough to support your workpiece comfortably and long enough to run through the table saw.
Attach the Fence: Securely attach the fence piece to the base, ensuring it’s perfectly parallel to one edge of the base. This fence will run along the table saw’s rip fence, guiding the jig and workpiece.
Design the Pivot Point: The key to a taper jig is a pivot point. This allows you to set the desired angle. You can achieve this by:
- Angled Cut Method: Cut an angled slot into the base where the workpiece will rest. The angle of this slot determines the taper angle.
- Pivot Block Method: Attach a small block of wood to the base. Your workpiece will pivot around a screw or bolt inserted through this block and into the workpiece.
Incorporate Angle Adjustment: You need a way to set and lock the angle. This can involve:
- Slot and Bolt: Cut a long slot in the base at an angle. Use a bolt, washer, and knob or nut to secure the workpiece at the desired position within the slot.
- Protractor System: Integrate a protractor head or a marked arc to accurately set your angles.
Workpiece Attachment: Consider how you’ll hold the wood to the jig. For repeatable cuts or larger pieces, a clamp system or even a simple screw through a pre-drilled hole into the workpiece can be effective.

Using Your Taper Jig:

Set the Angle: Determine the desired taper angle. You can calculate this or use a protractor.
Position the Workpiece: Place your workpiece on the jig and secure it. Ensure the starting point of the taper is aligned correctly.
Align with the Blade: Place the jig against the rip fence and position the blade so it will start the cut at the correct point on your workpiece.
Make the Cut: Hold the jig firmly against the rip fence and push the workpiece through the blade.
Repeat (if necessary): For opposing tapers, you might need to adjust the jig or workpiece position.

Advantages of Using a Taper Jig:

Accuracy: Provides a stable and consistent guide for precise angles.
Repeatability: Once set, you can make multiple identical tapered cuts.
Safety: Keeps your hands away from the blade and provides a stable platform.
Versatility: Can be adjusted for various taper angles and workpiece sizes.

2. Cutting Tapers with a Table Saw Miter Gauge Taper

The table saw miter gauge, when used creatively, can also be employed to cut tapers. This method is particularly useful for smaller workpieces or when you need to cut tapers on the ends of boards.

How it Works:

The miter gauge typically slides in the table saw’s miter slots, allowing you to guide the workpiece across the blade at an angle. To cut a taper, you’ll need to create an angled support for your workpiece relative to the miter gauge.

Methods for Miter Gauge Tapers:

Angled Block Attached to Miter Gauge:
1. Create a small wooden block with an angled top.
2. Securely attach this block to the miter gauge head.
3. Place your workpiece on the angled block.
4. Set the miter gauge to your desired taper angle.
5. Slide the miter gauge across the table saw, cutting the taper.
Wedge Jig with Miter Gauge:
1. Construct a simple wedge. This is essentially two pieces of wood joined at an angle.
2. Secure one side of the wedge to the table saw workbench (or a sacrificial board attached to the saw table).
3. Place the miter gauge against the angled face of the wedge.
4. Position your workpiece against the miter gauge and the wedge.
5. Slide the miter gauge, guided by the wedge, to make the taper cut.

Important Considerations for Miter Gauge Tapers:

Workpiece Stability: Ensuring the workpiece doesn’t shift during the cut is crucial. Use clamps if possible.
Length of Cut: This method is best for shorter tapers. Long tapers can be difficult to manage safely and accurately with a miter gauge.
Angle Accuracy: Precisely setting the angle of your block or wedge is key.

3. Using a Table Saw Bevel Jig

A table saw bevel jig is designed for making angled cuts on the edge of a workpiece. While not directly for cutting a taper along the length of a board, it can be adapted for creating tapered edges or for making the initial angled cut that forms part of a larger tapering operation.

How it Works:

A bevel jig typically attaches to the table saw’s miter gauge or rip fence. It provides a surface that you can tilt to a specific angle, allowing the blade to cut at that angle.

Applications for Tapering:

Creating Angled Edges: If you need to create a tapered edge on a board, you can set up a bevel jig to make a consistent angled cut along the length.
As part of a Jig: A bevel jig could be incorporated into a custom table saw jig to achieve a specific tapering effect.

Limitations:

A standard bevel jig is less suited for cutting a taper that reduces the width of a board along its entire length, as it primarily cuts an angle along the edge.

4. The Table Saw Tapering Fence (Sliding Fence)

A table saw tapering fence is a specialized attachment that replaces or complements your existing rip fence. It allows you to set a precise angle for cutting tapers without needing a separate jig.

How it Works:

These fences usually have a pivot point, allowing you to swing the fence away from the blade at a set angle. The workpiece is then pushed against this angled fence, guiding it through the blade for a tapered cut.

Features of a Table Saw Tapering Fence:

Adjustable Angle Scale: Marked increments for precise angle setting.
Secure Locking Mechanism: To hold the fence at the desired angle.
Smooth Sliding Action: To maintain contact with the rip fence or table saw bed.

Advantages:

Convenience: Eliminates the need for a separate jig for every taper.
Speed: Faster setup for repetitive tapering tasks.
Accuracy: Provides a stable and adjustable guiding system.

Disadvantages:

Cost: These are specialized accessories and can be more expensive than building a basic jig.

5. Making Tapers Table Saw with a Dado Blade Taper (Advanced)

While not the most common method for general tapering, a dado blade setup can be used for specific tapering tasks, particularly when creating grooves or rabbets that are tapered.

How it Works:

A dado blade creates a wide, flat-bottomed cut. By tilting the table saw blade (if your saw has a true tilting arbor) or by using a jig that guides the workpiece at an angle relative to the dado blade, you can create tapered grooves or rebates.

Considerations:

Blade Tilt: This requires a table saw with a tilting arbor (blade tilts, not the table).
Jigging: You would still need a jig to control the angle of the cut relative to the dado blade.
Precision: Achieving a smooth taper with a dado blade can be challenging and may require multiple passes.

6. Freehand Tapering (Not Recommended for Beginners)

While technically possible, freehand tapering directly on the table saw without any guides or jigs is highly discouraged for safety and accuracy reasons. This method involves marking the taper line on the wood and carefully guiding the wood along the blade. The risk of kickback and inaccurate cuts is very high.

Setting Up for Taper Cuts

Regardless of the method you choose, proper setup is paramount for cutting accurate and safe tapers.

Calculating Taper Angles and Dimensions

Before you cut, you need to know your taper dimensions.

Taper per Inch: This is the most common way tapers are described. For example, a “1-inch taper per foot” means the wood reduces by 1 inch in width over a 12-inch length.
Angle: You can convert taper per inch to an angle using trigonometry. The formula involves the arctangent of half the taper width divided by the length.

Example: If you want a taper that reduces the width by 2 inches over a 12-inch length:
* The reduction on each side is 1 inch.
* The angle is the arctangent of (1 inch / 12 inches).
* This calculates to approximately 4.76 degrees.

Preparing Your Workpiece

Square Edges: Ensure the edges of your workpiece that will be used as reference against the rip fence or jig are square and true.
Marking: Clearly mark your taper lines if you are using a method that requires visual alignment.

Blade Height and Settings

Blade Height: For most taper cuts, set the blade height so it extends about 1/8 to 1/4 inch above the workpiece. This provides a clean cut without excessive blade exposure.
Blade Type: A good quality, sharp crosscut or general-purpose blade is usually sufficient for taper cuts.

Advanced Techniques and Custom Table Saw Jigs

For those looking to refine their taper-cutting skills or tackle complex projects, creating custom table saw jigs offers immense flexibility.

The Power of Custom Jigs

Custom table saw jigs allow you to tailor your tools to specific tasks. For tapers, this could mean:

Repeatable Tapers: A jig designed to hold multiple identical pieces for rapid tapering.
Complex Shapes: Jigs that allow for compound tapers or tapers on curved surfaces.
Increased Safety: Jigs with integrated hold-downs and anti-kickback features.

Examples of Custom Jigs:

Offset Taper Jig: For creating tapers on the inside or outside of a workpiece.
Table Saw Taper Jig with Hold-Downs: Incorporating cam clamps or toggle clamps for secure workpiece holding.
Compound Taper Jig: For creating tapers on multiple faces simultaneously, often requiring a tilting table saw.

Troubleshooting Common Taper Cutting Issues

Even with the best setups, you might encounter problems.

Wobbly or Inconsistent Tapers

Cause: Loose jig, workpiece shifting, dull blade, or inconsistent feed rate.
Solution: Ensure all connections on your jig are tight. Secure your workpiece firmly. Use a sharp blade and maintain a steady feed rate.

Tear-Out

Cause: Dull blade, cutting with the grain in a way that lifts fibers.
Solution: Use a sharp blade, consider a fine-toothed blade, or use a sacrificial strip of wood behind your workpiece to support the exiting cut. Scoring the line with a utility knife before cutting can also help.

Kickback

Cause: Workpiece binding on the blade, improper feeding, or fence misalignment.
Solution: Always maintain a firm grip on your jig or workpiece, keep it firmly against the fence or jig guide, and feed smoothly. Ensure your blade is aligned with the miter slots.

FAQs About Cutting Tapers on a Table Saw

Here are some frequently asked questions about making tapers on a table saw.

Q1: What is the best way to cut a taper on a table saw?

The “best” way depends on your needs, but using a well-built table saw taper jig is generally considered the most accurate, safe, and repeatable method for most applications.

Q2: Can I cut a taper on a table saw without a special jig?

Yes, you can use your miter gauge with an angled block or a wedge jig. However, these methods might be less accurate and more challenging for longer tapers or larger workpieces.

Q3: How do I calculate the angle for a taper?

You can calculate the angle using trigonometry. If you know the total width reduction (W) over a length (L), the angle (θ) is the arctangent of (W/2 / L). For example, a 1-inch taper per foot (12 inches) means W = 1 inch. So, θ = arctan(0.5 / 12) ≈ 2.38 degrees. However, many taper jigs have built-in guides or protractors to help set angles directly.

Q4: What kind of blade should I use for cutting tapers?

A sharp, general-purpose or crosscut blade is usually suitable. For very fine woodworking and to minimize tear-out, a blade with more teeth and a cleaner cutting profile is beneficial.

Q5: How do I make parallel tapers on opposite sides of a board?

To make parallel tapers on opposite sides, you’ll typically need to make two cuts. After the first taper cut, you’ll need to reposition the workpiece or jig to make the second cut at the same angle but on the opposite edge, ensuring the tapers are parallel. This often involves flipping the workpiece or adjusting the jig’s setup.

Q6: Is it safe to cut tapers on a table saw?

Yes, it can be safe if you follow proper procedures and use appropriate jigs or guides. Always prioritize safety, keep your hands clear of the blade, use push sticks, and ensure your workpiece is securely held.

Mastering the art of cutting tapers on a table saw opens up a world of design possibilities in your woodworking projects. By employing the right jigs, understanding the techniques, and always prioritizing safety, you can confidently achieve precise and beautiful tapered shapes. Whether you’re building furniture, crafting tools, or adding decorative flair, the table saw is your ally in creating these essential woodworking elements.
