A dovetail jig is a woodworking tool designed to create precise dovetail joints, which are commonly used in furniture making and cabinetry. These joints are known for their strength and aesthetic appeal, as they interlock in a way that resists pulling apart. The jig guides the router or saw, ensuring consistent and accurate cuts for each joint. Dovetail jigs come in various styles, including handheld and table-mounted versions. They often feature adjustable templates to accommodate different sizes and types of dovetails. Using a dovetail jig can significantly improve the efficiency and quality of woodworking projects, making it a valuable tool for both beginners and experienced woodworkers.
