How To Cut a Zero Clearance Insert With Riving Knife: A Detailed Guide

By Avi Green October 04, 2023

Have you ever wondered how to cut a zero clearance insert with riving knife in a way that boosts your woodworking precision?

As a BBQ enthusiast, you might think this topic is far removed from grilling. But understanding the art of precision cutting with a riving knife can transform your approach to cutting meat, vegetables, and even delicate pastries.

What Is a Zero Clearance Insert and a Riving Knife?

A zero clearance insert is a custom-made insert meant to close the gap between the blade and the saw table, minimizing tear-out. A riving knife, on the other hand, is a safety feature installed behind the saw blade to prevent the material from pinching the blade and causing kickback.

Step-by-Step Guide on Cutting a Zero Clearance Insert with Riving Knife

Materials Needed

Table saw
Riving knife
MDF or plywood for the insert
Pencil and measuring tape
Drill and bit

Step 1: Remove the Original Insert

First, remove the original insert from the table saw. Typically, this requires unscrewing it from its slots.

Step 2: Measure and Cut the Base Material

Use MDF or plywood. Measure and cut it to the exact size of the original insert.

Step 3: Install the Riving Knife

With the base plate cut, install your riving knife before making any cuts. This safety measure will guide the kerf of the cut.

Step 4: Make the Cut

Place the new insert on the table and slowly raise the saw blade through the insert, creating a slot that fits perfectly around the blade and riving knife.

Troubleshooting Common Issues

Sometimes the insert may not fit perfectly. In such cases, sand down the edges or use a chisel to get a snug fit.

Safety Tips

Always keep your hands at a safe distance from the blade. Also, ensure the saw is turned off when making adjustments.
