Table Saw Cutting Methods: Ripping and Crosscutting

The two primary table saw cutting methods are ripping and crosscutting.

Ripping Wood on a Table Saw

Ripping is cutting wood along the grain. Here’s how to rip safely and accurately:

1. Set the Fence: Adjust the fence to the desired width.
2. Position the Wood: Place the wood against the fence, keeping it flat on the table.
3. Turn on the Saw: Allow the blade to reach full speed before starting the cut.
4. Feed the Wood: Push the wood through the blade, keeping it firmly against the fence. Use a push stick to guide the wood near the blade.
5. Maintain a Steady Pace: Avoid stopping or hesitating during the cut.
6. Use Outfeed Support: Support the wood as it exits the blade to prevent tipping.

Crosscutting with a Table Saw

Crosscutting is cutting wood against the grain. Here’s how to crosscut safely and precisely:

1. Use the Miter Gauge: Place the wood against the miter gauge.
2. Set the Angle: Adjust the miter gauge to the desired angle.
3. Turn on the Saw: Let the blade reach full speed.
4. Feed the Wood: Push the miter gauge forward, guiding the wood through the blade.
5. Keep the Wood Secure: Hold the wood firmly against the miter gauge to prevent it from shifting.

Other Table Saw Cutting Methods

• Bevel Cuts: Tilting the blade allows you to make angled cuts on the edge of the wood.
• Dado Cuts: Using a dado blade or multiple passes, you can create grooves in the wood.
• Rabbet Cuts: Cutting a recess along the edge of the wood.

Table Saw Techniques for Enhanced Precision

Mastering table saw techniques can greatly improve the accuracy and quality of your cuts.

Using Featherboards

Featherboards provide consistent pressure against the fence, ensuring the wood stays tight against the fence during ripping. They are particularly helpful when cutting long pieces or when making repetitive cuts.

Implementing Stop Blocks

Stop blocks are used to make repetitive cuts of the same length. They are attached to the fence and act as a physical stop for the wood, ensuring each piece is cut to the exact same size.

Employing Table Saw Jigs

Table saw jigs are specialized devices that enhance the saw’s capabilities. Some common jigs include:

• Tapering Jig: Used for cutting tapers on furniture legs or other projects.
• Tenoning Jig: Used for cutting tenons for mortise and tenon joints.
• Box Joint Jig: Used for cutting box joints, also known as finger joints.

Cutting Thin Strips

Cutting thin strips on a table saw requires extra caution. Always use a push stick or paddle to keep your hands away from the blade. Consider using a dedicated thin strip jig for added safety and accuracy.

Managing Internal Stress in Wood

Wood can have internal stresses that cause it to warp or move when cut. To minimize this, make shallow cuts first and gradually increase the depth of cut. This allows the wood to adjust to the changes in stress.

Table Saw Blade Selection: Choosing the Right Blade for the Job

Selecting the right table saw blade is crucial for achieving clean cuts and maximizing the saw’s performance.

Types of Table Saw Blades

• General Purpose Blades: A good all-around choice for ripping and crosscutting.
• Ripping Blades: Designed for fast, efficient ripping with minimal tear-out.
• Crosscutting Blades: Produce clean, smooth crosscuts with minimal splintering.
• Combination Blades: Offer a compromise between ripping and crosscutting performance.
• Dado Blades: Used for cutting wide grooves or dados.
• Specialty Blades: Include blades for cutting non-ferrous metals, plastics, and other materials.

Blade Tooth Configuration

• Tooth Count: Higher tooth counts produce smoother cuts but cut slower. Lower tooth counts cut faster but may leave a rougher finish.
• Tooth Angle: The angle of the teeth affects the cutting action. Positive tooth angles are more aggressive, while negative tooth angles produce smoother cuts.
• Tooth Grind: The shape of the teeth affects the cutting performance. Common tooth grinds include:
  • Flat Top Grind (FTG): Best for ripping.
  • Alternate Top Bevel (ATB): Best for crosscutting.
  • Combination Grind: A combination of FTG and ATB teeth, suitable for general-purpose use.

Blade Materials

• High-Speed Steel (HSS): A common blade material for general-purpose use.
• Carbide-Tipped: Carbide is a very hard material that stays sharp longer than HSS. Carbide-tipped blades are ideal for cutting hardwoods and abrasive materials.
