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, making them a popular choice for connecting pieces of wood. The jig guides the router or saw, ensuring consistent and accurate cuts. Dovetail jigs come in various styles, including handheld and table-mounted versions. They typically feature adjustable templates that allow woodworkers to customize the size and spacing of the dovetails. Using a dovetail jig can significantly speed up the joint-making process while maintaining high-quality results.
