Why Cut Tapers?
Tapers are not just for aesthetics. They serve several practical purposes in woodworking:
- Furniture Design: Many furniture legs have a slight taper to make them look more graceful and stable.
- Strength and Stability: Tapered joints can be stronger than straight ones. For example, a tapered tenon fitting into a tapered mortise creates a very secure connection.
- Ease of Assembly: In some cases, a slight taper can make fitting parts together easier.
- Weight Reduction: Tapering can reduce the weight of a component without significantly compromising its strength.
- Aesthetics: A well-executed taper can add visual appeal and sophistication to a project.
Tools You’ll Need
To cut a taper on your table saw, you’ll need a few essential items:
- Table Saw: The centerpiece of the operation.
- Table Saw Blade: A sharp, high-quality blade is crucial for clean cuts.
- Push Stick: For safety, always use a push stick when feeding material through the saw.
- Measuring Tape and Pencil: For marking your taper.
- Combination Square or Speed Square: For drawing straight lines and checking angles.
- Safety Glasses: Always wear safety glasses when operating power tools.
- Hearing Protection: Table saws can be loud.
- Dust Mask: Protect your lungs from sawdust.
- Taper Jig: This is the most important accessory for accurate taper cutting. We’ll cover how to make one.
Methods for Cutting Tapers
There are several ways to approach cutting tapers on a table saw. The most common and accurate methods involve using a jig.
Method 1: Using a Simple Taper Jig (The Most Common Approach)
A taper jig is a device that guides your workpiece past the table saw blade at a specific angle. This is the most reliable method for consistent results.
How to Make a Taper Jig
Making your own table saw taper jig is a rewarding project that offers excellent precision.
Materials:
- A piece of plywood or MDF (at least 1/2 inch thick) for the base. A good size is around 24 inches long by 10 inches wide.
- A scrap piece of hardwood or plywood for the fence.
- Wood screws.
- Wood glue.
- Clamps.
Construction Steps:
- Cut the Base: Cut your plywood or MDF to the desired size. This will be the main body of your jig.
- Cut the Fence: Rip a piece of hardwood or plywood to create a fence. This fence will ride against your table saw’s miter slot or rip fence. Ensure it’s perfectly straight. It should be long enough to provide good support.
- Attach the Fence: Apply wood glue to the edge of the base where the fence will attach. Position the fence along one edge of the base, ensuring it’s flush and square. Secure it with wood screws from the underside of the base. Make sure the fence is parallel to the edge of the base that will align with the table saw’s miter slot or rip fence.
- Add a Stop Block (Optional but Recommended): For repeated tapers, you can add a stop block to one end of the jig. This helps ensure consistent starting points for each cut.
- Test Fit: Place the jig on your table saw. The fence should slide smoothly in the miter slot.
This table saw jig construction provides a stable platform for your tapering operations.
Cutting a Taper with Your Jig
- Set Up Your Table Saw: Install a sharp dado blade or a standard combination blade. Ensure the blade height is set correctly – just slightly higher than the thickness of your workpiece.
- Mark Your Taper: On your workpiece, draw a line indicating the taper. This line will represent the angle you want to cut.
- Position Your Workpiece on the Jig: Place your workpiece on the base of your taper jig. Align the edge of your workpiece with the edge of the jig that will be guided by the miter slot or rip fence.
- Set the Taper Angle: This is the crucial step. You’ll need to set the angle of the taper relative to the jig.
- Using a Protractor: If your jig has an adjustable fence or pivot point, you can set a specific angle using a protractor.
- Marking the Taper: A more common method is to mark the desired taper directly on the jig. Measure the taper you need at the end of your workpiece and mark this distance on the jig’s base, starting from the fence. For example, if you want a 1-inch taper over 12 inches of length, you would mark 1 inch from the fence at the desired end point.
- Secure the Workpiece: Use clamps (hand clamps or specialized jig clamps) to hold the workpiece firmly to the jig. Ensure the clamps do not interfere with the blade path.
- Make the Cut: Slide the jig with the clamped workpiece into the miter slot. Feed the jig smoothly through the blade, keeping the fence snug against the miter slot or rip fence. Let the blade do the work.
- Repeat for the Other Side: For a symmetrical taper, you’ll typically need to repeat the process on the opposite side of the workpiece. You might need to adjust your jig setup or the workpiece placement to achieve this. For example, you could flip the workpiece or reposition it on the jig.
This method is excellent for accurately cutting angles table saw applications.
Method 2: Using a Table Saw Sled Taper Attachment
A table saw sled taper attachment is a variation of the taper jig, often built directly onto a crosscut sled. This offers even greater stability, especially for longer workpieces.
How to Make a Table Saw Sled Taper Attachment
- Build a Basic Crosscut Sled: If you don’t have one, build a standard crosscut sled. This involves two runners that fit into your table saw’s miter slots, a back fence, and a table.
- Create a Taper Fence: Cut a piece of plywood or MDF that is the same width as your sled’s table.
- Attach the Taper Fence at an Angle: This is where the tapering happens. You’ll need to attach this new fence to the sled’s table at a specific angle.
- Marking: Place your workpiece on the sled. Mark the desired taper on the workpiece.
- Using a Spacer Block: A common technique is to use a block of wood as a spacer. Place this block against the sled’s back fence. Then, position your taper fence against this block and secure it to the sled’s table with screws. The thickness of the spacer block determines the angle of the taper. You can experiment with different block thicknesses to achieve various taper angles.
- Using an Angle Gauge: For more precise angles, you can use a digital angle gauge to set the taper fence to a specific degree relative to the sled’s runners.
Cutting a Taper with a Sled Attachment
- Set Up: Ensure your sled’s runners fit snugly in the miter slots.
- Position Workpiece: Place your workpiece on the sled’s table, aligning it against the angled taper fence.
- Make the Cut: Push the sled through the table saw blade. The taper fence will guide the workpiece at the desired angle.
- Repeat: For symmetrical tapers, you’ll need to reposition or flip your workpiece and repeat the cut.
This method is particularly useful for table saw rip cuts where you need to taper the entire length of a board.
Method 3: Using the Table Saw Rip Fence (for Very Specific Applications)
While not as versatile or safe as using a jig, it’s theoretically possible to cut a taper by adjusting the rip fence as you make the cut. This method is generally not recommended for beginners or for precise tapers due to the inherent dangers and difficulty in control.
This method is more suited for cutting angles table saw scenarios where the angle is very shallow and you are very experienced.
Method 4: Using a Dragging Technique (Not Recommended for Accuracy)
Some methods involve using a block to “drag” the workpiece away from the blade as you push it through. Again, this lacks precision and is not a recommended technique for consistent results.
Advanced Techniques and Considerations
Tapering Wood on Table Saw with Compound Angles
For tapers that also involve bevels, you’ll need to combine jig use with a tilting table saw blade. This requires careful setup and precise measurements.
Table Saw Joinery and Tapers
Tapers are excellent for creating strong joinery, such as:
- Tapered Mortise and Tenon: A tapered tenon fits snugly into a correspondingly tapered mortise, creating a very strong mechanical joint.
- Dovetails: While not directly cut with a taper jig, the concept of angled cuts is fundamental to dovetail joinery.
- Half-Lap Joints: Tapers can be incorporated into half-lap joints for added strength and visual appeal.
Common Mistakes to Avoid
- Not Using a Jig: Trying to freehand tapers is extremely dangerous and rarely results in accurate cuts.
- Blade Height Too High: A blade that is too high can lead to tear-out and dangerous kickback.
- Insecure Clamping: If the workpiece is not firmly secured to the jig, it can shift during the cut, ruining the taper and posing a safety risk.
- Not Accounting for Blade Kerf: Remember that the blade removes material (the kerf). Your measurements need to account for this.
- Pushing Too Fast: Let the saw do the work. Forcing the workpiece can lead to overheating, burning, and inaccurate cuts.
- Ignoring Safety: Always wear safety gear and use push sticks.
Taper Jig Design Variations
Your table saw taper jig doesn’t have to be a simple rectangle. You can customize it for specific needs:
Adjustable Taper Jigs
These jigs allow you to adjust the angle of the taper without having to build a new jig. This typically involves a pivot point and a way to set the desired angle.
Repeat Taper Jigs
As mentioned earlier, adding stop blocks or adjustable markers can help you create identical tapers on multiple pieces quickly and accurately.
Jig for Tapering Multiple Pieces
If you need to taper many pieces of the same size and angle, you can design a jig that holds several workpieces at once, ensuring consistency across the batch.
Frequently Asked Questions (FAQ)
Q: Can I cut a taper on a table saw without a jig?
A: While technically possible for very shallow tapers and experienced users, it is highly not recommended due to safety risks and lack of accuracy. Using a taper jig is the safest and most effective method.
