Step-by-Step Guide to Cutting Dado Joints

Cutting dado joints with a standard table saw blade involves precision and careful execution. Here’s a detailed guide:

1-Measuring and Marking the Wood

Begin by precisely measuring the width and depth of the dado cut required for your project. Mark these measurements clearly on the wood using a pencil and a ruler or square. Accuracy in this step is crucial for a perfect fit.

Marking the Wood

2-Setting the Blade Height

Adjust the height of the saw blade to match the depth of the dado cut. It’s better to start shallower and gradually increase the depth. Use a piece of scrap wood to test the depth, making adjustments until you achieve the desired depth.

3-Adjusting the Rip Fence

The rip fence on your table saw will guide the wood to ensure a straight cut. Align the rip fence with the marks on your wood, ensuring it is parallel to the blade. For wider dadoes, you’ll need to move the fence and make multiple passes.

Adjusting the Rip Fence:

4-Making the First Pass

With the wood firmly against the rip fence, gently push it through the blade using a push stick for safety. Keep the wood steady and the feed rate consistent for a clean cut.
