Understanding the Tangential Saw: A Simple Guide



Woodworking is a rewarding craft, but mastering the tools is crucial. One often overlooked yet incredibly versatile tool is the tangential saw, also known as a rip saw. Unlike crosscut saws which slice across the grain, tangential saws cut with the wood grain, making them ideal for specific woodworking tasks. This article will demystify the tangential saw, exploring its design, applications, and proper usage.


1. Anatomy of a Tangential Saw: Teeth and Their Purpose



The key to understanding a tangential saw lies in its teeth. Unlike crosscut saws with teeth designed for shearing the wood fibers, a tangential saw boasts teeth shaped for ripping. These teeth are typically larger, wider, and spaced farther apart. Imagine a shark's tooth – that's a good visual representation. Their shape and spacing are crucial for efficiently removing wood fibers along the grain.

The larger tooth size allows for more aggressive material removal. Each tooth removes a chunk of wood, rather than slicing delicately like a crosscut saw. The wider tooth profile creates a wider kerf (the width of the cut), and the greater spacing reduces friction, preventing the saw from binding in the wood. This is especially important when dealing with harder woods. Finally, the angle of the tooth rake (the angle the tooth is set at) is designed to efficiently remove the wood fibers with minimal resistance.


2. When to Use a Tangential Saw: Ideal Applications



Tangential saws excel in applications requiring cuts parallel to the wood grain. Here are some prime examples:

Ripping lumber: This is the most common application. Imagine you have a 2x4 and need to cut it into two 1x4s. A tangential saw is the perfect tool for this job. The cut will be clean and straight, provided proper technique is used.

Resawing: Resawing is the process of cutting a thicker piece of wood into thinner boards. This is frequently used to create veneers or thinner pieces from a valuable piece of timber. A tangential saw’s aggressive cutting action makes this task much easier than with a crosscut saw.

Making parallel cuts for joinery: Certain joinery techniques, like creating straight edges for butt joints or mortise and tenon joints, often require perfectly parallel cuts. A tangential saw allows for precise cuts along the grain.


3. Using a Tangential Saw Effectively: Techniques and Safety



Proper technique is key to achieving clean, accurate cuts with a tangential saw.

Sawing stance: Maintain a comfortable and balanced stance, holding the saw firmly but not rigidly. Avoid applying excessive pressure; let the saw's weight and momentum do the work.

Starting the cut: Begin your cut slowly and steadily. Applying too much pressure at the beginning can cause the saw to bind or wander.

Maintaining a consistent pace: Once the cut is started, maintain a smooth, even pace throughout. Avoid jerking or forcing the saw.

Following the grain: Keep the saw blade aligned with the wood grain. This prevents the saw from binding and produces a cleaner, smoother cut.

Safety precautions: Always wear safety glasses to protect your eyes from flying wood chips. Secure the wood firmly to a workbench to prevent movement during cutting. Use a push stick for added safety, especially when cutting smaller pieces.


4. Tangential Saw vs. Crosscut Saw: Key Differences



The main difference lies in the tooth design and intended application. A crosscut saw is designed to cut across the grain, making it ideal for trimming and crosscutting lumber. Its smaller, more numerous, and sharper teeth shear the wood fibers. In contrast, a tangential saw’s larger, spaced-out teeth are made for ripping along the grain. Confusing them can lead to inefficient cuts and potentially damaged tools.


5. Key Takeaways



The tangential saw, while often overlooked, is a powerful and essential tool for any woodworker. Understanding its design, proper application, and safety precautions will significantly improve your woodworking skills and efficiency. Choose the right saw for the job, respecting the grain direction for optimal results and safety.


FAQs



1. Can I use a tangential saw for crosscutting? While possible, it’s highly inefficient and will likely result in a rough, jagged cut. Crosscut saws are far better suited for crosscutting.

2. What type of wood is best suited for a tangential saw? Tangential saws can handle most woods, but softer woods are generally easier to cut. Harder woods require more care and potentially a sharper saw.

3. How do I sharpen a tangential saw? Sharpening a tangential saw requires specific tools and techniques. It's best to consult a professional or watch instructional videos before attempting it.

4. What is the difference between a rip saw and a tangential saw? They are essentially the same thing. "Rip saw" is a more common and readily understood term for a tangential saw.

5. Are there different types of tangential saws? Yes, there are hand saws and power saws designed for ripping. Hand saws offer more control for delicate work, while power saws are far more efficient for large projects.

How to Measure radial and tangential angles on saw blades 25 Aug 2008 · In this app you can use saw blade diameter as a reference if it's known, then you can take a picture of tips and make measurements on the picture. You can take a picture of the part you are interested only, since you just need a peace of the reference object to put three markers on the circle.

Clearance – Circular Saw Blades Angles describing circular saw blade clearance are: hook angle, top clearance, top bevel angle, radial and tangential side angles. The first is the hook angle, which shows how the front of the tooth addresses the piece to be cut.

Saw Tip Angles Explained - Carbide Processors Tangential Clearance Angle (Side Clearance Angle) You measure down the side of the tip and the difference it is the difference between front and back. As you cut material it gets compressed and springs back after the cutting edge passes.

What are the 4 types of timber conversion? – Quick-Advice.com 17 Nov 2020 · Wood is cut longitudinally in two different planes: tangential and radial. Tangential sections are made perpendicular to the rays and tangential to the annual rings and face of the log. This plane is also called slab-cut or plane-sawed lumber.
