Leigh RTJ400 Router Table Dovetail Jig
Another great innovation by Leigh

Router tables are exceedingly popular and can be found in most shops. The Leigh RTJ400 Router Table Dovetail Jig is designed specifically for router table use, providing fast and accurate routing of through dovetails, box joints and half-blind dovetails, all on your router table. The Leigh RTJ400 Template is precision CNC machined from aircraft grade aluminum for perfect joinery every time.

Create all this joinery on one Jig.

Versatility is a key feature of the Leigh 16"(400mm) RTJ400 Jig. It makes 5 sizes of through dovetails at two different pitches, 3 sizes of single pass half-blind dovetails, and 4 sizes of box joints (finger joints). Perfect joint fit is guaranteed and repeatable with the patented Leigh elliptical guide bushing.

Leigh RTJ400 instructional videos are a great resource to learn about router table joinery. Use a portable device in the shop to watch and learn right in front of the jig.

IMPORTANT Router Table Requirements

Router tables are typically used with a bearing or fence, however, the Leigh RTJ400 is guided around a guide bushing mounted in the router table. Leigh eBush guide bushings are designed to the decades-old Porter Cable/Black & Decker industry standard. Therefore, you will need an insert ring to fit the included eBush to your router table or router plate. See specifications below.

Leigh eBush and Nut

To fit the eBush to your router table insert plate, you need a 1-3/8" diameter counter bore insert ring. Check with your router table or router plate (router lift) manufacturer, as to what adaptation, if any, is required.
