The Basics of Ripping on a Table Saw

Ripping on a table saw is a common woodworking task. It means cutting a piece of wood along the direction of the grain, making it narrower. Unlike crosscutting, which cuts across the grain, ripping usually results in longer, thinner pieces of wood. Here’s a breakdown of the essential elements:

Table Saw Ripping Techniques: The Step-by-Step Guide

Here’s a simplified way to rip wood, breaking down each step:

1. Think and Plan: Before you begin, know the width you want and double-check your measurements.
2. Choose the Right Blade: Pick a ripping blade. These blades are made to cut smoothly along the wood grain.
3. Set Up the Fence: Set the rip fence to the width you need. Measure from the blade to the fence to be sure.
4. Keep It Safe: Wear safety glasses and hearing protection. Make sure your workspace is clear.
5. Turn It On: Turn on the saw and let it get up to full speed.
6. Feed the Wood: Hold the wood flat against the table and the fence. Push it through the blade at a steady speed.
7. Use a Push Stick: When the wood gets close to the blade, use a push stick to finish the cut. This keeps your hands away from danger.
8. Turn It Off: After the cut, turn off the saw and wait for the blade to stop before you pick up the wood.

Table Saw Rip Fence Setup: Accuracy is Key

The rip fence is your guide. Setting it up correctly is very important for making straight cuts. Here’s how to do it right:

• Measure Carefully: Use a good measuring tape to set the distance between the blade and the fence. Measure at both the front and the back of the blade to make sure the fence is parallel.
• Lock It Down: After setting the fence, lock it tightly in place. A loose fence can move during the cut, making the cut uneven.
• Double-Check: Before turning on the saw, double-check the fence setting. A quick check can save you from making mistakes.
• Use Featherboards (Optional): Featherboards hold the wood tight against the fence. This helps keep the wood moving straight and reduces vibration.

Ripping Wood Grain Direction: Why It Matters

Wood has a grain, which is the direction the wood fibers run. Ripping means cutting along this grain. This is different from crosscutting, where you cut across the grain. Cutting with the grain makes the cut cleaner and easier.

• Find the Grain: Look at the wood. You’ll see lines running along its length. That’s the grain.
• Rip with the Grain: Always feed the wood into the saw so the blade cuts along the grain. This makes the cut smoother and reduces the chance of the wood splintering.
• Watch for Grain Changes: Sometimes the grain can change direction. If you see this, be extra careful. It might be harder to push the wood through the saw, and the wood might splinter.

Ripping Wood Safely: Essential Safety Tips

Safety is most important when using a table saw. Here are some key safety tips:

• Wear Safety Gear: Always wear safety glasses to protect your eyes from flying wood chips. Hearing protection is also a good idea, as table saws can be loud.
• Use a Push Stick: A push stick keeps your hands away from the blade. Use it to push the wood through the last part of the cut.
• Keep a Safe Distance: Never put your hands directly in line with the blade. Keep them to the side and out of the path of the wood.
• Stand to the Side: Stand slightly to the side of the blade, not directly behind it. This way, if the wood kicks back, it won’t hit you.
• Don’t Reach Over the Blade: Never reach over the blade while the saw is running. If you need to adjust the wood, turn off the saw first.
• Be Alert: Pay attention to what you’re doing. Don’t get distracted, and don’t rush.
• Check the Wood: Look for knots or loose pieces. These can cause the wood to kick back.

Preventing Kickback When Ripping: A Critical Skill

Kickback is when the wood suddenly shoots back toward you. It’s dangerous and can cause serious injuries. Here’s how to prevent it:

• Use a Riving Knife or Splitter: The riving knife or splitter is a metal piece behind the blade that keeps the cut wood from pinching the blade. Always use it.
• Use Featherboards: Featherboards hold the wood tight against the fence, which helps prevent it from twisting and binding.
• Feed at a Steady Pace: Don’t push too fast or too slow. Keep a steady pace.
• Keep the Wood Flat: Make sure the wood stays flat on the table and tight against the fence.
• Watch for Binding: If the wood starts to bind, stop the saw and find out what’s causing it. Don’t force it.
• Use Anti-Kickback Pawls: Anti-kickback pawls dig into the wood if it starts to move backward. These can help prevent kickback.

Push Stick for Ripping: Your Hand’s Best Friend

A push stick is a simple tool that helps you push the wood through the saw without putting your hands too close to the blade.

• How to Use It: Use the push stick to push the last part of the wood through the blade. Keep your hand on the handle and push firmly.
• Types of Push Sticks: There are many types of push sticks. Some are simple sticks with a notch, while others are more complex with handles and grips.
• Make Your Own: You can easily make your own push stick from a piece of scrap wood. Make sure it’s strong and comfortable to hold.

Choosing the Right Tools and Materials

Using the right tools and materials is essential for safe and accurate ripping.

Ripping Blade Selection: Finding the Perfect Match

The right blade makes a big difference in how well the wood cuts and how safe the process is.

• Ripping Blades: Ripping blades have fewer teeth than crosscut blades. The teeth are designed to remove wood quickly along the grain.
• Blade Size: Make sure the blade is the right size for your saw.
• Tooth Design: Look for blades with a flat-top grind. This design is best for ripping.
• Blade Quality: Buy a good-quality blade. A sharp blade cuts cleaner and is safer to use.

Best Wood for Ripping: Considerations for Different Species

Some woods are easier to rip than others. Here’s what to consider:

• Softwoods: Softwoods like pine and cedar are generally easier to rip because they are softer and have a straighter grain.
• Hardwoods: Hardwoods like oak and maple can be harder to rip, especially if they have knots or irregular grain.
• Plywood: Plywood can be tricky to rip because it is made of layers of wood glued together. Use a blade with more teeth to reduce splintering.
• Check for Knots: Avoid ripping wood with large knots. Knots can cause the wood to bind or kick back.

Table Saw Ripping Speed: Finding the Right Pace

The right speed is important for both safety and cut quality.

• Don’t Rush: Don’t push the wood through the saw too fast. This can cause the blade to bind or kick back.
• Steady Pace: Keep a steady pace. If you push too slow, the wood can burn.
• Listen to the Saw: Listen to the sound of the saw. If it sounds like it’s working too hard, slow down.

Table Saw Ripping Troubleshooting: Solving Common Problems

Sometimes things go wrong when ripping wood. Here’s how to fix common problems:

• Wood Binding: If the wood starts to bind, stop the saw and find out what’s causing it. It could be a knot, a warped board, or a misaligned fence.
• Burning: Burning happens when the blade gets too hot. This can be caused by pushing the wood too slowly or using a dull blade.
• Splintering: Splintering happens when the blade tears the wood fibers. This can be caused by using the wrong blade or pushing the wood too fast.
• Uneven Cut: An uneven cut can be caused by a loose fence or pushing the wood unevenly.
• Kickback: If the wood kicks back, stop the saw and check your setup. Make sure you’re using a riving knife or splitter and that the fence is properly aligned.

Here’s a table summarizing common issues, causes, and solutions:

Problem	Possible Cause(s)	Solution(s)
Wood Binding	Knot in the wood, warped board, misaligned fence	Stop the saw, remove the wood, inspect for issues, realign fence, use a sharp blade
Burning	Pushing wood too slowly, dull blade	Increase feed rate slightly, use a sharp blade, ensure proper dust collection
Splintering	Wrong blade, pushing wood too fast	Use a blade with more teeth, reduce feed rate, use a zero-clearance insert
Uneven Cut	Loose fence, uneven pushing	Tighten fence, ensure fence is parallel to the blade, maintain consistent pressure on the wood
Kickback	Pinching, binding, not using riving knife/splitter	Ensure riving knife/splitter is installed, use featherboards, avoid knots, maintain consistent feed rate
