If you’re an avid woodworker or DIY enthusiast, you know how important it is to have a properly functioning table saw. One accessory that can greatly enhance the performance of your table saw is a zero clearance insert. A zero clearance insert is a custom-made throat plate that sits on top of the table saw and is designed to minimize chip-out and tear-out when cutting wood.
A zero clearance insert essentially provides a support surface for the wood being cut, preventing it from falling into the gap between the blade and the table. This not only improves the quality of your cuts but also helps to prevent accidents and injuries.
Making a zero clearance insert for your table saw is a relatively simple and cost-effective project that can be done in just a few steps. By following these instructions, you’ll be able to create a custom insert that perfectly fits your table saw and improves its performance.
Step 1: Measure and Prepare the Throat Plate
Start by removing the existing throat plate from your table saw. Use a caliper or ruler to measure the dimensions of the opening in the table saw. You’ll need these measurements to create the zero clearance insert.
Important tip: It’s recommended to use a hardwood material, such as plywood or MDF, for the zero clearance insert as it provides stability and durability.
Step 2: Cut the Insert Material
Using the measurements obtained from Step 1, cut the hardwood material to the appropriate size for the zero clearance insert. Make sure to cut it precisely and double-check the dimensions before proceeding.
Pro tip: It’s a good idea to make multiple inserts as backup in case one gets damaged or worn out. This way, your table saw will always be ready for use.
Step 3: Test and Fine-tune
After cutting the insert, place it onto the table saw and make sure it fits snugly in the opening without any gaps. If there are any gaps or the fit is loose, use sandpaper or a file to remove material from the edges until you achieve a perfect fit.
Expert tip: To further improve the performance of the zero clearance insert, you can apply a coat of wax or a low-friction coating to the surface. This will reduce friction and make the wood glide smoothly over the insert.
By following these simple steps, you can create a zero clearance insert for your table saw and enhance its cutting capabilities. With this insert in place, you’ll be able to achieve cleaner cuts, reduce tear-out, and improve the overall safety of your woodworking projects. So don’t hesitate to give it a try and experience the benefits for yourself!

Tools:
- Table saw
- Measuring tape
- Ruler or straightedge
- Utility knife
- Drill
- Screwdriver
- Sanding block
- Safety goggles
- Ear protection
- Dust mask
Materials:
- Plywood or MDF sheet
- Zero clearance insert plate
- 1/2 inch screws
Once you have gathered all the necessary tools and materials, you can start by measuring the dimensions of your table saw’s throat plate. Use a measuring tape to determine the width, length, and thickness of the existing plate.
Next, cut a piece of plywood or MDF sheet to the same dimensions as the existing throat plate. Use a ruler or straightedge to ensure straight and accurate cuts. This will serve as the base for your zero clearance insert.
Using a utility knife, trace the outline of the existing throat plate onto the plywood or MDF sheet. This will give you a guide for cutting out the opening for the blade. Make sure to align the outline carefully to ensure an accurate fit.
After tracing the outline, carefully cut out the opening for the blade using a utility knife. Take your time and make smooth, precise cuts to ensure a clean and accurate fit.
Once the opening is cut out, place the zero clearance insert plate on top of the plywood or MDF base. Align it with the opening and use a ruler or straightedge to make sure it is centered and level.
Secure the zero clearance insert plate to the base using 1/2 inch screws. Pre-drill holes to prevent splitting and use a screwdriver to tighten the screws securely.
Finally, sand down any rough edges or imperfections on the zero clearance insert. This will ensure smooth and precise cuts when using your table saw.
With the preparation complete, you are now ready to install your newly made zero clearance insert into your table saw. Follow the manufacturer’s instructions for your specific model to ensure proper installation and alignment.
Selecting the Right Material
When making a zero clearance insert for your table saw, selecting the right material is crucial for its performance and longevity. The material should be strong, stable, and able to withstand the pressure and friction generated during cutting.
One popular choice for a zero clearance insert is plywood. Plywood is affordable, readily available, and easy to work with. However, it may not be as durable as other materials and can warp over time due to moisture and temperature changes.
Another option is high-density fiberboard (HDF) or medium-density fiberboard (MDF). These materials are denser and more stable than plywood, making them a suitable choice for a zero clearance insert. They are also less prone to warping and have a smooth surface that helps reduce friction during cutting.
Alternatively, you can consider using phenolic resin. Phenolic resin is a durable and heat-resistant material commonly used in tooling applications. It offers excellent stability and can withstand the high temperatures generated by the saw blade without warping or melting.
Whatever material you choose for your zero clearance insert, make sure it is thick enough to provide adequate support for your workpiece. It should also be flat and smooth to ensure a flush fit with the table saw’s surface. Taking the time to select the right material will result in a high-quality and long-lasting zero clearance insert.
Measuring the Table Saw Slot
Before you start building a zero clearance insert for your table saw, it’s important to accurately measure the width and depth of the slot in your saw’s table. This measurement will ensure that your insert fits snugly and securely in the slot.
First, make sure your table saw is turned off and unplugged for safety. Then, remove any existing insert or throat plate from the table.
Measuring the Width
To measure the width of the slot, you’ll need a set of calipers or a measuring tape. Position the jaws of the calipers or tape measure into the slot, making sure to align them with the edges of the slot. Take note of the measurement, which will be the width of your table saw slot.
Measuring the Depth
To measure the depth of the slot, you’ll need a depth gauge or ruler. Place the gauge or ruler into the throat of the slot, ensuring it reaches the bottom. Take note of the measurement, which will be the depth of your table saw slot.
It’s good practice to take multiple measurements of both the width and depth to ensure accuracy. If the measurements vary slightly, use the average or the largest measurement to ensure a proper fit for your zero clearance insert.
Once you have your measurements, you can proceed to make a zero clearance insert that fits perfectly in your table saw slot.
Making the Zero Clearance Insert
Creating a zero clearance insert for your table saw is a straightforward process that can greatly enhance the safety and precision of your woodworking projects. Here is a step-by-step guide to help you make your own zero clearance insert:
1. Measure and Prepare the Materials
Start by measuring the dimensions of your table saw’s existing throat plate. This will serve as a template for your zero clearance insert. Use a sturdy and flat piece of material, such as plywood or MDF, that matches the thickness of the original throat plate.
2. Cut and Shape the Insert
Using your measurements, carefully cut the material to the same size as the original throat plate. Next, mark the position of the blade on the insert and use a router or chisel to remove the excess material. This will create a slot that perfectly aligns with the blade.
3. Add Support and Leveling Screws
To ensure stability and a flush fit, attach small strips of wood to the underside of the insert. These strips will act as supports and prevent the insert from sagging or warping over time. Additionally, install leveling screws at each corner of the insert, allowing you to adjust its height and achieve a seamless fit with the table surface.
4. Sand and Finishing
Smooth out any rough edges or imperfections on the insert using sandpaper. Pay close attention to the area around the blade slot to ensure a tight fit. Once sanded, consider applying a finish to the insert, such as varnish or polyurethane, to protect the material and make it easier to clean.
Remember, always prioritize safety when working with power tools. Use appropriate safety gear, such as safety glasses and gloves, and take your time to ensure accurate measurements and cuts. With a well-made zero clearance insert, you can enjoy cleaner cuts and reduce the risk of kickback during your woodworking projects.
Trace the Outline of the Existing Insert
Before making a zero clearance insert for your table saw, you need to trace the outline of the existing insert. This will help you create a precise and accurate template for the new insert.
Start by removing the existing insert from your table saw. Carefully lift it out and set it aside.
Place a thin piece of plywood or hardboard on top of the opening where the insert was. Make sure the plywood or hardboard is larger than the opening, so you have room to trace the outline.
Align the edges of the plywood or hardboard with the edges of the opening. Use clamps or weights to hold it securely in place.
Once the plywood or hardboard is in position, take a pencil or marker and trace the outline of the opening onto the plywood or hardboard. Follow the contours of the opening precisely to ensure an accurate template.
Make sure to mark any screw holes or other features of the opening on the plywood or hardboard as well. These marks will help you position and secure the new zero clearance insert later on.
Once you have traced the outline and marked any necessary features, carefully remove the plywood or hardboard from the table saw. You can now use this template to create your own zero clearance insert.
Important tip: Double-check your measurements and make any necessary adjustments before cutting out the new insert. Accuracy is key to ensuring a proper fit and safe operation of your table saw.
