The revolutionary Isoloc joint represents the first entirely practical alternative to the traditional half-blind dovetail. Read on to find out how easy it is to rout these stunning joints.

Remove the guide finger assembly and slide the Isoloc Template onto your jig in seconds.

Template scale has inch and metric measurement.
To set up for pins and sockets, the template is shifted left or right (see arrow), and the control pin at the right end of the template secures the template in place (see inset image). The template is in the pin mode in the image above.

VGS Variable Guide Bush System
When attached to your router base, Leigh’s unique VGS guarantees easy and precise joint fit with its three tapered guide bushings*, one for each comb size.
This adjustable 3-piece guide bushing mounts to your router base. Rotating the tapered barrel of the VGS, up or down, increases or decreases its active diameter.
* Patented in USA, Canada and Europe
3-piece Variable Guidebush System (VGS)
Rotating the barrel of an installed VGS 1/8 of a turn adjusts joint fit by a incredible 1/1000 of an inch! Pin wrench included.
Rotating the tapered barrel of the VGS up or down changes its active diameter.
The VGS mounts directly to many router bases. Some routers may require a Leigh guide bushing adaptor. Click here for Guide Bushing Adaptor Selector
