Cutting dados with a table saw requires precision, careful setup, and understanding of blade configurations. Woodworkers use dados for creating strong, stable joints in cabinetry, shelving, and furniture construction. This comprehensive guide will walk you through the essential techniques, safety protocols, and expert strategies for achieving perfect dados every time.
What Are the Essential Preparations for Dado Cutting?
Select the Right Dado Blade
Table saw dados can be cut using two primary blade types:
| Blade Type | Characteristics | Best Used For |
|---|---|---|
| Stacked Dado Set | Multiple chipper blades between outer blades | Precise, wide cuts |
| Wobble Dado Blade | Single blade that tilts | Quick, less precise cuts |
How Do You Configure the Dado Blade?
Stacked Dado Set Configuration
- Arrange outer blades facing outward
- Stack chipper blades alternately
- Use spacers for precise width adjustment
- Maximum typical depth: 1 inch
What Safety Precautions Should You Take?
Critical Safety Measures
- Always use push sticks
- Wear safety glasses
- Remove loose clothing
- Keep hands away from blade
- Use blade guard when possible
How to Achieve Precise Dado Cuts?
Blade Height and Alignment
- Use engineer’s square to verify 90-degree blade angle
- Adjust blade height precisely
- Make test cuts on scrap wood
- Verify cut depth and width before final project cut
What Are the Step-by-Step Cutting Techniques?
