Using the DeWalt 7491 Table Saw
Now that you have set up your DeWalt 7491 and familiarized yourself with its controls, it’s time to get to work.
Basic Cutting Techniques
Here are some foundational cutting techniques to get started with your table saw:
Cross-Cutting
Cross-cutting involves cutting across the grain of the wood product. Follow these steps:
- Adjust the Blade: Set the blade to the desired height, typically just above the thickness of the material.
- Align the Fence: Use the rip fence to ensure your cut is straight. Place your workpiece against the fence.
- Power On and Feed the Wood: Start the saw, then gently push the wood through the blade using a push stick for safety.
Rip Cuts
Rip cuts are made along the grain of the wood. Here’s how to execute a rip cut:
- Set the Rip Fence: Adjust the rip fence according to the width you desire for the cut.
- Cutting Position: While holding the wood against the fence, engage the power saw and slowly feed the wood.
- Avoid Force: Let the saw do the work; don’t force wood through the blade.
Advanced Techniques and Applications
Once you’re comfortable with basic cuts, explore more advanced techniques.
Bevel Cuts
The DeWalt 7491 allows users to create bevel cuts, important for making angles.
- Adjust the Bevel Angle: Use the bevel adjustment knob to set your desired angle.
- Test Cut: It’s wise to make a test cut on a scrap piece of wood to ensure the angle is correct before cutting your project.
Dado Cuts
Dado cuts create channels in wood, essential for joinery.
- Use a Dado Blade: Ensure the saw blade is properly installed.
- Set the Height: Adjust the dado blade height according to the depth you require.
- Make Multiple Passes: It’s effective to take multiple shallow cuts rather than one deep cut to achieve the desired width.
