The Try Square Is Made At A Fixed

The Try Square: Precision at a Fixed Angle

The humble try square, a seemingly simple tool, is the cornerstone of accurate woodworking. Its unassuming design, featuring a fixed 90-degree angle, belies its crucial role in ensuring precise cuts, accurate joinery, and the overall quality of any woodworking project. Understanding the nuances of this fundamental tool, from its construction and materials to its various applications and maintenance, is essential for any woodworker, from beginner to expert.

Understanding the Geometry of the Try Square

At its core, the try square's function relies on its fixed 90-degree angle. This precision is paramount. Deviations, however slight, can lead to cumulative errors that significantly impact the final product. The square's design utilizes two key components:

The Blade and the Stock

• The Blade: This is the long, flat, and usually accurately-ground metal component of the square. It's crucial that the blade remains perfectly straight and true for accurate measurements and marking. Variations in the blade’s straightness will directly affect the accuracy of the square.

• The Stock: This is the shorter, typically thicker piece of metal or wood that forms the right angle with the blade. The stock provides a stable base for the woodworker to hold and accurately position the blade against the workpiece. The stock's design and material impact the overall durability and feel of the try square.

The precise joining of the blade and stock at a perfect right angle is what makes the try square such an invaluable tool. This accuracy isn't just about manufacturing; it's also about maintenance and usage. A damaged or misused try square will quickly lose its accuracy, rendering it unreliable for precision work.

Materials Used in Try Square Construction

The materials used to construct a try square significantly influence its durability, accuracy, and overall performance. High-quality try squares are built to last a lifetime, requiring minimal maintenance and delivering consistent precision.

Metal Try Squares

Metal try squares, typically made from hardened steel, are renowned for their durability and accuracy. The hardened steel blade resists bending and wear, ensuring that the 90-degree angle remains consistent even with extensive use. These squares are generally more expensive but offer superior longevity and accuracy compared to wooden options. The metal stock can also be constructed from steel or another durable metal, providing robust support for the blade.

Wooden Try Squares

Wooden try squares, often crafted from hardwoods like rosewood or maple, offer a different set of advantages. While not as durable or as accurate as metal squares, they provide a gentler touch on delicate workpieces and can be appealing aesthetically. The wood's inherent properties can influence how the square feels in the hand, which might be preferred by some woodworkers. However, wooden squares require more care and are more prone to warping or damage over time. Regular inspection and maintenance are vital for maintaining accuracy.

Choosing the Right Try Square

The selection of a try square depends on the specific needs and preferences of the woodworker. Factors to consider include:

• Size: Try squares come in various sizes, with blade lengths ranging from a few inches to over a foot. The appropriate size depends on the size of the workpieces. Larger squares are ideal for larger projects, while smaller squares are more suitable for intricate detail work.

• Material: The choice between metal and wood depends on the desired level of accuracy, durability, and budget. Metal squares are more accurate and durable but more expensive, while wooden squares are more affordable but require more maintenance.

• Construction Quality: A well-made try square should have a precisely formed 90-degree angle, a straight and true blade, and a sturdy, well-attached stock. Inspecting the square before purchase is crucial. Look for any visible flaws or imperfections that might compromise its accuracy.

• Handle Design: The handle, or stock, should be comfortable to hold and provide a secure grip. Ergonomic designs minimize hand fatigue, particularly during extended use.

Applications of the Try Square

The try square's versatility extends across numerous woodworking applications. Its primary function is testing for squareness, but its uses are far more extensive:

Marking Square Lines

This is the try square's most basic application. By holding the stock firmly against the edge of the workpiece, the blade can accurately mark a line perpendicular to the edge. This is essential for creating accurate cuts and joinery.

Checking Squareness

The try square allows woodworkers to verify the squareness of cuts, ensuring that components fit together precisely. This is particularly important in joinery where even minor inaccuracies can result in gaps or misalignment.

Marking Angles Other Than 90 Degrees

While primarily a 90-degree tool, the try square can be used in conjunction with other tools, like a bevel gauge, to transfer and mark angles other than 90 degrees. By setting the bevel gauge to the desired angle and using the try square as a guide, one can accurately transfer this angle to the workpiece.

Laying Out Complex Joints

The try square is fundamental to laying out many woodworking joints, including mortise and tenon, dovetail, and miter joints. Its precision helps woodworkers ensure accurate placement of joinery elements, leading to strong and stable joints.

Checking Alignment

Beyond individual pieces, the try square helps check the alignment of assembled components. By using the square on assembled pieces, one can identify and correct any misalignment before proceeding to further steps. Early identification and correction saves significant time and effort in the long run.

Maintenance and Care of the Try Square

Proper maintenance and care are essential for preserving the accuracy and longevity of a try square.

Regular Cleaning

Keep the blade and stock clean of sawdust, wood chips, and other debris that can accumulate during use. Regular cleaning prevents the build-up of materials which may affect the square's accuracy. A soft cloth and a mild cleaning agent are ideal.

Checking for Accuracy

Periodically, check the accuracy of the try square. Simple methods involve using a precision square or another trusted square to test the accuracy of the 90-degree angle. If inaccuracies are detected, consider professional sharpening or repair.

Storing Properly

Store the try square in a safe place, away from potential damage or impact. A dedicated tool organizer or a protective sheath can help prevent damage during storage and transportation.

Avoiding Impacts

Avoid dropping or impacting the try square, as this can damage the blade and affect its accuracy. Careful handling is vital to its continued precision.

Advanced Techniques with the Try Square

Experienced woodworkers use the try square in more sophisticated ways:

Marking Angles Using the Blade and Stock

By combining the blade and stock, and applying simple geometry, the try square can be used to mark various angles with relative ease. This technique requires an understanding of basic trigonometry and geometry, but once mastered can enhance the woodworking process.

Using the Try Square to Test for Squareness in Larger Projects

While initially used for smaller pieces, the try square can be applied to check the squareness in larger constructions, such as frames or boxes. This often involves multiple checks and ensuring consistent squareness across various planes.

Combining the Try Square with Other Measuring Tools

The try square forms a key element in a set of woodworking tools, frequently employed in combination with rulers, marking gauges, and other measuring tools. This synergistic use expands its capabilities significantly.

Conclusion: The Enduring Importance of the Try Square

The try square, despite its simplicity, is a vital tool in any woodworker's arsenal. Its ability to ensure accuracy in a wide array of applications underlines its importance. From marking precise lines to checking the squareness of intricate joints, the try square plays a pivotal role in achieving high-quality woodworking results. Understanding its construction, materials, proper usage, and maintenance is essential for any woodworker seeking to create beautiful and functional pieces. Investing in a high-quality try square is an investment in precision and the overall quality of your woodworking projects, ensuring that the foundation of your work is strong and accurate. The fixed 90-degree angle, while seemingly simple, is the key to a lifetime of precise woodworking.
