What Is A Try Square

What is a Try Square? A practical guide for Woodworkers and DIY Enthusiasts

The humble try square, often overlooked amidst the power tools and advanced machinery of modern woodworking, remains an indispensable tool for any serious woodworker, DIY enthusiast, or anyone working with precise measurements and angles. Day to day, this article will look at the intricacies of the try square, exploring its design, various types, applications, and how to properly use and maintain one. We'll cover everything from its fundamental principles to advanced techniques, ensuring you gain a complete understanding of this essential tool.

Understanding the Fundamentals of a Try Square

A try square is a simple yet remarkably versatile hand tool used primarily for marking perfectly square lines on wood and other materials. Its basic design consists of two parts: a blade (typically made of hardened steel) and a stock (usually made of hardwood, sometimes metal). The blade is rigidly attached to the stock at a precise 90-degree angle. This right angle is crucial for its functionality. The try square's accuracy depends on the precision of this 90-degree angle, making it a crucial tool for ensuring accuracy in woodworking projects.

The Components and Their Importance

• Blade: The blade is the working part of the try square, used to scribe accurate lines. A well-made blade will be straight, flat, and free from burrs or imperfections. The material and finish of the blade directly influence its longevity and performance. Higher-quality blades will often have a hardened steel construction to prevent wear and tear.

• Stock: The stock provides the stable base for the try square. Its material, typically hardwood such as beech or maple, needs to be durable and resistant to warping. The stock's size and shape affect the ergonomics and ease of use. A well-designed stock allows for a comfortable and secure grip.

Types of Try Squares: Choosing the Right Tool for the Job

While the basic design remains consistent, try squares come in various sizes and styles, each suited for specific applications. Understanding these variations is crucial for selecting the right tool for your needs.

1. Steel Try Squares:

These are typically considered the workhorse of try squares, combining durability and accuracy. Steel stocks and blades ensure longevity and resistance to wear. The steel construction makes them suitable for heavy-duty tasks and more demanding environments. On the flip side, steel try squares can be heavier than other types.

2. Wood Try Squares:

Wood try squares, usually made with hardwood like beech or maple, offer a more traditional aesthetic and can be surprisingly accurate. They are generally lighter than steel squares and often preferred for more delicate work or applications where the weight of a steel square might be cumbersome. Even so, they are more susceptible to damage from impacts and humidity changes.

3. Combination Squares:

These versatile tools combine the functionality of a try square with a sliding head that allows for various measurements and angle adjustments. A combination square is significantly more versatile than a basic try square, offering functions for measuring depth, marking angles, and even scribing lines parallel to an edge. This versatility makes it a worthwhile investment for woodworkers who need a multi-functional tool.

4. Marking Gauges:

While not strictly a try square, marking gauges are closely related and share a similar principle. A marking gauge uses a pointed scriber to create consistent parallel lines. These are indispensable for marking out consistent widths when cutting multiple pieces of wood or creating grooves and dadoes.

Applications of a Try Square: Beyond the Basics

The applications of a try square extend far beyond simply marking 90-degree angles. Its precise right angle is the foundation for many woodworking techniques, ensuring accurate and efficient work.

1. Checking Squareness:

This is the most fundamental application of a try square. By placing the blade against one edge of a workpiece and the stock against another, you can instantly determine if the two edges are truly square (at a 90-degree angle) to each other. Any gap or overlap indicates the workpiece is not square.

2. Marking Out Cuts:

The try square allows for the precise marking of cutting lines on wood, ensuring accurate cuts when using saws, chisels, or other cutting tools. Accurate markings are crucial for achieving clean, straight cuts and avoiding wasted material.

3. Establishing Squareness in Assembly:

Before gluing up joints, using the try square ensures the pieces are properly aligned at 90 degrees, leading to strong, stable joints. This is particularly critical for accurate joinery like butt joints, miter joints, and mortise and tenon joints.

4. Setting Up Jigs and Fixtures:

Try squares play a vital role in setting up jigs and fixtures for woodworking. Ensuring that the components of jigs are square and aligned guarantees accurate results during operations such as routing, planing, and shaping.

5. Marking Parallel Lines:

By sliding the blade along the edge of a workpiece, you can accurately mark parallel lines. This is essential for tasks such as creating consistent dadoes, rabbets, or grooves.

6. Checking Miter Cuts:

While not directly measuring miter angles (45 degrees), a try square can assist in checking the accuracy of a cut by comparing the angle against a known square edge, revealing any discrepancies.

Using a Try Square Effectively: Techniques and Tips

Proper technique is essential to maximize the accuracy and efficiency of using a try square. Here are some key tips:

• Hold it firmly: Maintain a firm grip on both the blade and stock, ensuring the square is stable against the workpiece. A wobbly square leads to inaccurate markings.

• Keep it tight: Ensure the blade and stock are snug against the workpiece, preventing any gaps that could lead to inaccurate measurements.

• Use a pencil: Use a sharp pencil to mark your lines, ensuring a fine, visible line for accurate cutting.

• Check from multiple angles: Always check your squareness from multiple angles to ensure accuracy, as a single check may not reveal slight inaccuracies.

• Regularly check for accuracy: Over time, try squares can lose their accuracy due to wear and tear. Periodically check the squareness of your try square using a more precise measuring tool to confirm its accuracy.

Maintaining Your Try Square: Extending Its Lifespan

Proper care and maintenance will extend the lifespan of your try square and ensure its continued accuracy.

• Keep it clean: Regularly clean the blade and stock with a soft cloth to remove any sawdust or debris that could interfere with its accuracy.

• Store it properly: Store your try square in a safe, dry place, away from moisture and extreme temperatures. A dedicated tool case or drawer is ideal.

• Avoid dropping it: Dropping your try square can damage the blade or stock, compromising its accuracy. Handle it with care.

• Sharpen the blade (if necessary): For steel blades, periodic sharpening will maintain its crispness and improve marking clarity.

Frequently Asked Questions (FAQ)

Q: What is the difference between a try square and a combination square?

A: A try square is primarily for checking squareness and marking 90-degree angles. A combination square offers more versatility, including measuring depth, marking angles other than 90 degrees, and scribing lines parallel to an edge. Small thing, real impact.

Q: How can I check if my try square is accurate?

A: You can check your try square's accuracy by using a more precise measuring tool, like a precision square or a digital angle finder. You can also use the “crossing the lines” method, comparing the measurement of two adjacent angles with the other adjacent angles made with the same square.

Q: What material is best for a try square?

A: Both hardened steel and high-quality hardwood offer advantages. Steel is more durable and resistant to wear, while hardwood is lighter and often preferred for finer work.

Q: Can I use a try square on materials other than wood?

A: Yes, try squares can be used to check squareness and mark lines on various materials, including metal, plastic, and even some types of stone, provided the material's surface is sufficiently smooth and flat.

Q: How do I choose the right size try square?

A: The size of the try square you choose depends on the size of your workpieces. Larger squares are better suited for larger projects, while smaller squares are more suitable for nuanced detail work. Consider having several sizes available for different applications.
