Leigh

The Leigh D4R Pro is a variable-spacing router dovetail jig used for cutting through-dovetails, half-blind dovetails, and box joints. It accommodates stock up to 24 inches wide and allows full control over pin and tail spacing and angle.

Through-dovetails are visible from both sides of the joint, making them a decorative feature in boxes and carcase construction. Half-blind dovetails conceal the joint from the front face, which is why they're standard for drawer fronts where you don't want the joinery visible.

Yes — unlike fixed-pitch dovetail jigs, Leigh jigs use individually adjustable fingers that let you set the pin and tail spacing anywhere within the jig's range, giving you the ability to mimic hand-cut proportions.

Leigh jigs require matched dovetail and straight bits used with specific guide bushing diameters. The 11 Pc RTJ400 Accessory Router Bit Bushing Kit provides compatible bits and bushings for the RTJ400 system.

The Leigh D24 is an accessory that mounts to Leigh D-series jigs to provide router support and connect vacuum dust collection directly at the template fingers, improving chip clearance and cut accuracy.

Leigh jigs have a learning curve due to their adjustability, but they include detailed setup guides and the variable spacing capability makes them more versatile than entry-level fixed-pitch jigs. Beginners often find them rewarding once the initial setup is understood.

Yes — several combination packages are available, including the D4R Pro with D24 Vacuum Support and bundles that include Infinity Tools router bit sets, so you have everything needed to start cutting dovetails immediately.

The Leigh Router Table Dovetail Jig is designed for router table use and cuts through-dovetails and box joints, offering the same adjustable-pitch approach as the benchtop D-series jigs.
