Building Your Own Table Saw Taper Jig

If you decide to build a DIY taper jig, here’s a basic design you can follow.

Materials Needed

• 3/4″ Plywood
• Wood Screws
• T-Track (optional but recommended for adjustability)
• Knobs and Bolts (for locking the angle)
• Measuring Tools (ruler, protractor, etc.)
• Wood Glue

Step-by-Step Instructions

1. Cut the Base: Cut a piece of plywood to serve as the base of the jig. The size will depend on the typical length of the wood you intend to taper. A good starting point is 24 inches long and 12 inches wide.
2. Attach the Fixed Fence: Cut a straight piece of wood to serve as the fixed fence. This should run along one edge of the base and be perpendicular to the blade. Attach it securely with wood glue and screws.
3. Create the Adjustable Fence: Cut another piece of wood for the adjustable fence. This fence will pivot to create the desired angle. If you’re adding T-track, now is the time to install it along the base where the adjustable fence will pivot.
4. Install Pivot Point: Attach a bolt and knob to create a pivot point for the adjustable fence. This allows you to swing the fence to the desired angle.
5. Add Locking Mechanism: Install a locking mechanism to secure the adjustable fence at the chosen angle. This could be as simple as a bolt and wing nut or a more sophisticated clamp.
6. Test and Adjust: Before cutting any workpieces, test the jig with scrap wood to ensure the angle is accurate and the jig is stable.

Table Saw Tapering Techniques

Now that you have a taper jig, it’s time to learn the table saw tapering techniques necessary for achieving precise angled cuts table saw.

Calculating the Taper Angle

Before you start cutting, you need to calculate the correct angle for your taper. This depends on the desired difference in width between the two ends of your workpiece and the length of the workpiece.

• Formula:
  • Angle = arctan((Difference in Width / 2) / Length).
• Example:
  • If you want to taper a leg from 2 inches to 1 inch over a length of 24 inches:
    • Difference in Width = 2 - 1 = 1 inch
    • Angle = arctan((1 / 2) / 24) = arctan(0.02083) ≈ 1.19 degrees

Setting Up Your Table Saw

1. Blade Height: Adjust the blade height so it’s just above the thickness of your workpiece.
2. Fence Position: Position the taper jig against the table saw fence. Make sure the adjustable fence is set to the correct angle and securely locked.
3. Safety Checks: Double-check that all locking mechanisms are tight and the workpiece is securely clamped in the jig.

Cutting the Taper

1. First Cut: With the table saw running, slowly push the jig and workpiece through the blade. Maintain a steady feed rate and keep your hands away from the blade.
2. Second Cut: For a four-sided taper, rotate the workpiece 180 degrees within the jig and repeat the cut.
3. Repeat as Needed: If necessary, adjust the jig and repeat the process for the remaining sides of the workpiece.

Ensuring Accurate Taper Cuts

To ensure accurate taper cuts, consider the following tips:

• Precise Measurements: Double-check all measurements and angle settings.
• Secure Clamping: Make sure the workpiece is securely clamped in the jig to prevent movement during the cut.
• Consistent Feed Rate: Maintain a consistent feed rate to avoid uneven cuts.
• Test Cuts: Always make test cuts on scrap wood before cutting your final workpiece.
• Calibrate Your Tools: Regularly calibrate your table saw and measuring tools to ensure accuracy.

Safety First: Cutting Tapers Safely

Cutting tapers safely on a table saw is paramount. Here are essential safety precautions to keep in mind:

Essential Safety Gear

• Safety Glasses: Always wear safety glasses to protect your eyes from flying debris.
• Hearing Protection: Table saws are loud; wear hearing protection to prevent hearing damage.
• Dust Mask: Wear a dust mask to avoid inhaling sawdust.
• Push Sticks/Pads: Use push sticks or pads to keep your hands away from the blade.

Safe Practices

• Keep Hands Clear: Never place your hands directly in the path of the blade.
• Use Featherboards: Featherboards can help keep the workpiece tight against the fence and table, preventing kickback.
• Avoid Rushing: Take your time and focus on the task at hand. Rushing can lead to mistakes and accidents.
• Inspect Equipment: Before each use, inspect your table saw and jig for any damage or loose parts.
• Unplug When Adjusting: Always unplug the table saw before making any adjustments or changing the blade.

Dealing with Kickback

Kickback is a dangerous phenomenon that can occur when cutting on a table saw. It happens when the blade catches the workpiece and throws it back towards the operator. Here’s how to prevent and handle kickback:

• Prevention:
  • Use a riving knife or splitter to keep the kerf open.
  • Use featherboards to maintain consistent pressure.
  • Avoid cutting warped or twisted wood.
  • Use a sharp blade.
• Handling:
  • Stand to the side of the blade, not directly behind it.
  • Maintain a firm grip on the workpiece or jig.
  • If kickback occurs, don’t try to stop the workpiece. Let it go and step away.
