SIX EXTRAORDINARY JOINT PATTERNS

It's no accident the dovetail joint has endured through centuries of hand cut joinery as the sole design for mechanically interlocked corner joints. After all, if your saw and chisel are made to cut straight lines, how can you cut dovetails any other way? It took the development of hand-held routers and the ingenuity of Leigh Industries to come up with a genuinely new hybrid dovetail design, the Isoloc* joint.

Leigh's revolutionary Isoloc joints represent the first entirely practical alternative to the traditional half-blind dovetail. With a Leigh 24” D4R or 16” D1600 Dovetail jig and a 24” or 16” Isoloc template, even novice woodworkers can produce strong, functional and distinctively attractive joints. Isoloc's fluid, eye-catching shapes range from original to whimsically entertaining.

By removing the Dovetail finger assembly and simply sliding on one of the three Isoloc templates, you are ready to produce some extraordinary joinery. Each template features two joint patterns, one design carefully CNC machined on each side. A single 5/16" or 8mm straight bit, preferably an upcut spiral, does all the cutting.

VGS Accuracy
Joint fit is easily and precisely controlled using Leigh's patented Variable Template Guidebush System (VGS), a unique adjustable 3-piece template guidebush set that can be adjusted up or down, changing the joint fit. Rotating the barrel 1/8 of a turn adjusts joint fit by a mere one thousandth of inch! The VGS, which comes standard with each Isoloc template, mounts in many router bases like an ordinary 2 piece screw on template guidebush or by using a Leigh template guidebush adaptor.

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, as illustrated in the photo gallery.

The name Isoloc was coined from two words: Iso from the Greek word isos, meaning equal, and loc, an abbreviation of lock.
