Isoloc Joint Templates for
D-series Dovetail Jigs
Attach an Isoloc Template to your Dovetail Jig and open up a world of joinery options.
These templates fit all 24" [610mm] D4R Pro, D4R, D4, D3, D1258 and D1258R Jigs
Even novice woodworkers can produce these extraordinary joints that are strong, functional and distinctively attractive.
By replacing the Dovetail finger assembly with one of three Isoloc templates, you are ready to produce some very creative
joinery. Each template features two joint patterns, one design carefully CNC machined on each side of the template.
A single 5/16” or 8mm straight bit, preferably an spiral upcut bit, does all the routing.
Isoloc Templates are designed primarily for half-blind joints, though several of the patterns can be set up to produce through and end-on-end joints. Inlaid and Shadow Inlaid joints give an even more intriguing look to the beautiful organic shapes of Isoloc joints.
Quick Template Setup
It takes less than a minute to replace the dovetail finger assembly on your Leigh Dovetail Jig with one of three Isoloc templates, and you’re ready to produce some very creative joinery. In fact, Isoloc joints are as easy to rout as finger/box joints and even easier than dovetails. Each template has two joint patterns. A single 5/16” or 8mm straight bit, preferably an upcut spiral, does all the routing.

What Router Should I Use?
Leigh recommends a midsize router, from 1-1/2 to 2-1/4 HP (9-13 amps) with a 1/2" collet. This size provides great power to weight ratio. Fixed base routers are ideal because they have a lower center of gravity with handles mounted to the router base rather than the motor, as with plunge routers. However, if you are proficient with the use of a plunge router, it works just as well. Learn more >
Guide Bushing Adaptors for your Router
All 3 templates need a router fitted with a Leigh guide bushing. Because the router industry isn't standardized, you may need an adaptor to fit the guide bushing to your router. Learn more >
Routing with Isoloc Templates requires a router with a 1/2" collet, and smaller bits require the use of collet reducer. Learn More >
