Adjustable Tenoning Jig

Build an easy-to-use adjustable tenoning jig for your table saw. Cut perfect tenons with smooth cheeks using this shop-made jig with micro-adjustment.

Upgrade your joinery game with this adjustable tenoning jig—a simple, reliable, and accurate way to cut clean, snug-fitting tenons on your table saw. Perfect for crafting mortise and tenon joints, this DIY jig ensures your tenons have smooth, glue-ready cheeks without the extra sanding or touch-up that typically comes with band saw or dado blade cuts.

This jig features a rock-solid fence and integrated clamp that firmly holds your workpiece in place for safe, repeatable cuts. A built-in micro-adjustment mechanism makes dialing in tenon thickness easy and precise—whether you're making two joints or twenty.

The design is easy to build with basic materials and doesn’t require complex joinery or hardware. Its three-part construction—a miter-slot-guided base, an adjustable vertical support, and a clamping assembly—makes this jig versatile and beginner-friendly, while still meeting the needs of advanced woodworkers.

If you're looking for a shop-made tenon jig that delivers pro-level results without the cost of commercial models, this project is the perfect weekend build. Add it to your table saw jig collection and enjoy fast, accurate tenon cuts for furniture, frames, and doors.
