Band Saw Circle Jig

Cutting perfect circles on a band saw can be tricky without the right setup. While a simple nail pivot might do the trick, this shop-made adjustable circle-cutting jig offers far greater precision, repeatability, and ease of use. Built from sturdy ¾" plywood, the jig features a sliding tongue that houses a pivot nail and is secured with a thumb screw and threaded insert for fast, accurate adjustments. The base is designed to mount to your band saw table using either clamps or a clever turn-button system, ensuring stability and alignment during every cut.

This woodworking plan walks you through each step, from constructing the base and backboard to installing the stop system and mounting hardware. You'll appreciate the thoughtful design details, like a bevel-ripped tongue for smooth sliding and a recessed stop to hold your settings firmly. Whether you're making curved furniture parts, round tabletops, or decorative circles, this jig will quickly become a go-to tool in your workshop, helping you achieve clean, consistent results with confidence.
