Squares, bevel gauges, and stair gauges are measuring tools commonly used in woodworking, carpentry, and other construction-related applications. They are designed to provide accurate and precise measurements for various tasks. Here's an overview of each tool:

1. Squares:

   • Try Square: A try square is a right-angled measuring tool with a handle and a straight metal blade, usually made of steel. It is used to check and mark 90-degree angles, ensuring the accuracy of corners, edges, and joints. Try squares are available in different sizes, with the most common being 6 inches and 12 inches.
   • Framing Square: A framing square, also known as a carpenter's square, is a large L-shaped tool consisting of a long arm and a shorter perpendicular arm. It is primarily used in framing and layout work, allowing for precise measurements, marking of angles, and checking for squareness.

2. Bevel Gauges:

   • Bevel Gauge: A bevel gauge, also called a sliding T-bevel, is a tool used to transfer angles from one surface to another. It consists of a handle and a blade that can be adjusted and locked at various angles. Bevel gauges are particularly useful for replicating and transferring non-90-degree angles accurately.

3. Stair Gauges:

   • Stair Gauge: Stair gauges, also known as stair saw gauges or stair layout gauges, are specialized tools used in stair construction and installation. They are typically T-shaped and attach to the blade of a carpenter's square or a framing square. Stair gauges allow for precise and consistent marking of tread and riser measurements when cutting stair components.

Usage of these tools:

• Squares: Squares are used for checking and marking right angles, ensuring accuracy in various woodworking and construction tasks, such as marking cuts, checking the squareness of assemblies, and laying out joinery.
• Bevel Gauges: Bevel gauges are used for transferring and replicating angles from one surface to another, making them handy for tasks such as marking angles for cutting or fitting components.
• Stair Gauges: Stair gauges are specifically used in stair construction to mark and layout accurate measurements for the treads and risers, ensuring consistent and properly fitted stairs.

Benefits of Squares, Bevel Gauges, and Stair Gauges:

• Accuracy: These tools allow for precise measurements and angle transfers, ensuring the accuracy of cuts, joints, and layouts.
• Versatility: Squares, bevel gauges, and stair gauges have multiple applications across woodworking, carpentry, and construction projects.
• Ease of Use: They are user-friendly tools that can be easily adjusted and locked into position for accurate measurements and markings.
• Durability: These tools are typically made from sturdy materials like steel or aluminum, ensuring durability and longevity.

In summary, squares, bevel gauges, and stair gauges are essential tools for woodworkers, carpenters, and construction professionals. They provide reliable and accurate measurements, ensuring precise cuts, layouts, and angles in various woodworking and construction projects.
