Why Cut Tapers?

Woodworking tapers serve multiple purposes:

  • Aesthetics: They add visual appeal and a handcrafted touch to projects. Think of tapered legs on tables, chairs, or lamps.
  • Functionality: Tapers can create tighter joints, especially in drawer construction or for creating a snug fit in wooden mechanisms.
  • Ergonomics: Tapered handles or grips can make tools and objects more comfortable to hold.
  • Material Reduction: In some cases, tapering can reduce weight without sacrificing structural integrity.

Safety First!

Before we even touch the table saw, safety is paramount. Always wear safety glasses to protect your eyes from flying debris. Ensure your hands are a safe distance from the blade at all times. Never reach over the blade. Understand your table saw’s safety features and ensure they are in good working order. Keep your work area clean and free of clutter.

Methods for Cutting Tapers

There are several effective ways to cut tapers on a table saw, each with its own advantages. We’ll focus on the most common and accessible methods.

Method 1: Using a Taper Jig

A table saw taper jig is an essential tool for accurately cutting tapers. It provides a stable guide for your workpiece, allowing you to set and repeat the desired angle.

Building Your Own Table Saw Taper Jig

You don’t need to buy an expensive jig; you can easily make one yourself. Here’s a basic design:

Materials:

  • 1/4″ or 1/2″ plywood or MDF (for the base)
  • 1×4 or 1×6 lumber (for the fence and support)
  • Wood screws
  • Wood glue
  • T-nuts and bolts (for adjustable angle) or a hinge
  • Clamps (optional, for added security)

Steps:

  1. Create the Base: Cut a piece of plywood or MDF to a suitable size, perhaps 12″ x 18″. This will be the base of your jig.
  2. Attach the Fence: Cut a piece of lumber to run along the miter slot of your table saw. This fence needs to be perfectly straight and flat. Secure it to the base using wood glue and screws, ensuring it’s flush with the bottom of the base and parallel to the edge that will align with the table saw fence.
  3. Design the Angled Piece: This is where the taper angle is set. You have two main options:
    • Fixed Angle: Cut a piece of plywood or MDF and attach it to the base at a fixed angle (e.g., 5 degrees) using glue and screws. This is simple but limits you to one angle.
    • Adjustable Angle: This is more versatile. You can use a hinge to attach a piece of wood to the base, allowing you to adjust the angle. Alternatively, you can create a sliding mechanism with T-nuts and bolts.
      • Hinge Method: Attach a piece of wood to the base with a strong hinge. You’ll need a way to lock the angle in place, perhaps with a couple of screws that go into pre-drilled holes on a marked angle guide.
      • Sliding Method: Cut a slot in the base. Attach your angled piece to the base using a T-nut and bolt that can slide within this slot. This allows for infinite angle adjustments.
  4. Add a Stop: For repeatable cuts, add a stop block to your jig. This can be a simple piece of wood attached to the base that your workpiece butts up against.
  5. Consider a Hold-Down: For longer or thinner pieces, a hold-down clamp integrated into your jig can be very beneficial.

Using Your Taper Jig:

  1. Set the Angle: Adjust your jig to the desired taper angle. Many jigs have a degree scale. If you’re building an adjustable one without a scale, you can use a protractor to set your angle.
  2. Attach the Workpiece: Place your workpiece on the jig and secure it. You can use clamps or, for a more permanent jig, attach it with screws or double-sided tape. The key is that the workpiece must be firmly held against the jig’s fence and the angled piece.
  3. Align with Table Saw Fence: Place the jig against your table saw’s rip fence. The base of the jig should run smoothly along the table saw insert.
  4. Make the Cut: Turn on your table saw. Feed the jig with the workpiece into the blade. Keep firm pressure against the rip fence and the jig’s fence. The blade will cut at the angle set by your jig.

Method 2: Using the Table Saw Bevel Cut Feature (with a Miter Gauge Setup)

This method is more direct but requires careful setup. It’s ideal for cutting tapers on the edge of a board.

Steps:

  1. Set the Blade Tilt: This is the core of this method. You’ll tilt your table saw blade to the desired taper angle. For instance, if you want a 5-degree taper on both sides of a leg, you’d set the blade to 5 degrees.
  2. Use a Miter Gauge: Insert your miter gauge into the miter slot.
  3. Create a Stop Block (Optional but Recommended): Attach a stop block to your miter gauge. This ensures consistent starting and stopping points for repeated cuts, crucial for making matching tapers.
  4. Position the Workpiece: Place your workpiece against the miter gauge. The edge you want to taper should be against the blade.
  5. Make the First Cut: Feed the workpiece through the blade, keeping it firmly against the miter gauge.
  6. Adjust for the Second Taper: This is where it gets tricky.
    • For opposing tapers (like on a table leg): After the first cut, you’ll need to reposition the workpiece. For a symmetrical taper, you’ll flip the workpiece and set it against the miter gauge again. The amount you offset the workpiece from the fence will determine the taper’s width. This is often done by trial and error or using a marking gauge.
    • Alternatively, for specific angles: You might need to adjust the fence position or use a different jig setup to control the second taper.

Important Considerations for Bevel Cuts:

  • Blade Height: The blade height affects the length of the taper. A higher blade creates a longer taper.
  • Miter Gauge Fence: Some miter gauges have an adjustable fence, which can be helpful for setting the offset.
  • Repeatability: Ensuring the workpiece is positioned identically for each cut is critical.

Method 3: Using a Table Saw Sled Taper Attachment

A table saw sled taper is a specialized jig that attaches to a standard crosscut sled. This offers excellent stability and accuracy.

Building a Table Saw Sled Taper Attachment:

This is an advanced jig design. You’ll typically build a standard crosscut sled first, then add a pivoting arm or angled fence to it.

Basic Concept:

  1. Build a Crosscut Sled: This is a standard woodworking jig with a fence that runs in the miter slot and a base that supports the workpiece.
  2. Add an Angled Flipper: You can create an angled fence that pivots on the sled’s base. This angled fence guides the workpiece at your desired taper angle.
  3. Secure the Angle: Use a locking mechanism (like a bolt through a slot) or a precise angle finder to set the taper.
  4. Using the Sled Taper: Place your workpiece against the angled fence on the sled. The sled runs in the miter slot, and the blade cuts the taper. By adjusting the pivot point and the angle of the fence, you can control the taper.

This method is excellent for making multiple identical tapered legs for furniture.

What is Chamfering on a Table Saw?

Chamfering on a table saw is the process of creating an angled edge or bevel on a workpiece. While often used interchangeably with “bevel cut,” chamfering specifically refers to creating a small, angled surface, often for decorative purposes or to break a sharp edge. You can achieve chamfers using the table saw blade tilt (Method 2) or by using a specialized jig. For very narrow chamfers, you can often achieve them by slightly tilting the blade and running the edge of the workpiece against the rip fence, though a dedicated chamfer jig or a carefully set taper jig is more accurate and safer for consistent results.

Making Tapered Legs Table Saw: A Practical Example

Let’s say you want to make four tapered legs for a small table. Each leg needs a taper from 2 inches wide at the top to 1 inch wide at the bottom, with a total length of 28 inches.

Using a Taper Jig:

  1. Set the Angle: For a 1-inch reduction over 28 inches, you’ll need to calculate the angle.
    • Total reduction = 2 inches – 1 inch = 1 inch.
    • This 1-inch reduction happens over the entire 28-inch length.
    • You can use trigonometry: tan(angle) = opposite / adjacent.
    • In this case, let’s consider half the reduction at each side of the leg for a symmetrical taper. If the leg is 2×2 inches square at the top, and tapers to 1×1 at the bottom, the reduction on each side is 0.5 inches.
    • tan(angle) = 0.5 inches / 28 inches.
    • angle = arctan(0.5 / 28) ≈ 1.02 degrees.
    • So, you’ll set your taper jig to approximately 1 degree.
  2. Prepare the Jig: Ensure your taper jig has a secure way to hold the workpiece.
  3. Mark and Cut:
    • Take your 28-inch leg blank.
    • Place it on the jig, aligning the top edge with the zero mark or your starting point on the jig.
    • Secure the workpiece.
    • Feed the jig and workpiece through the blade.
    • For the other side, you’ll need to flip the workpiece and reposition it against the jig’s fence to create the opposing taper. The key is ensuring the starting and ending points are consistent. You might want to mark a line on your jig or workpiece to ensure alignment.
  4. Repeat: Repeat the process for all four legs, ensuring consistency in the angle and the starting/stopping points.

Using Table Saw Bevel Cuts:

  1. Set Blade Tilt: Tilt your table saw blade to 1.02 degrees.
  2. Set Rip Fence: You’ll need to set your rip fence. The distance from the fence to the blade determines the taper width. This requires careful measurement and potentially some test cuts.
  3. First Taper: Place the leg blank against the rip fence. Make the cut.
  4. Second Taper: This is the most challenging part with this method. You’ll need to reposition the leg. If the leg is 2×2, you’ll likely need to set the rip fence at a different position for the second taper, and the workpiece will need to be offset to start the taper correctly. This is where marking and measuring are crucial.
    • For a 2×2 leg tapering to 1×1, you would make the first taper. Then, you would need to offset the workpiece from the fence by a specific amount and run the opposite edge through the angled blade.

The taper jig is generally the preferred method for making uniform tapers on table legs due to its repeatability and ease of setup.

Advanced Techniques and Jigs

  • Table Saw Sled Taper: As mentioned, a sled attachment provides great stability. It’s particularly useful for tapered drawer sides or when you need to cut a taper on a piece that might not be long enough for a standard taper jig.
  • Dovetail Jig Adaptation: Some woodworkers adapt parts of dovetail jigs or create similar sliding mechanisms to achieve precise taper adjustments.
  • Router Table Taper Jigs: While this article focuses on table saws, it’s worth noting that router tables can also be used for cutting tapers, often with similar jig principles.

Cutting Angles Table Saw: General Tips

When cutting any type of angled cuts table saw, remember:

  • Sharp Blade: A sharp blade is essential for clean cuts and reduced tear-out, especially on angled surfaces.
  • Test Cuts: Always make test cuts on scrap wood to verify your angle and settings before cutting your actual workpiece.
  • Grain Direction: Be mindful of grain direction. Avoid cutting tapers into very short grain sections, as this can lead to weakness.
  • Support: Ensure adequate support for your workpiece throughout the cut.

Table Saw Joinery with Tapers

Tapers can be used in various table saw joinery techniques:

  • Dovetails: While often cut with hand tools or a router, angled dovetail pins and tails can be achieved with careful table saw setups, often using a tapering jig on the tail board.
  • Box Joints: Creating tapered box joints can add a unique aesthetic and a stronger mechanical lock.
  • Mortise and Tenon: Tapered tenons can create a more secure and self-locking mortise and tenon joint.
