Fits 24″ D4R Pro, D4R, D4, D3 and D1258/R Dovetail Jigs
Finger joints, also called box joints, add visually striking symmetrical design to corner assemblies. Unlike dovetails, finger joints do not interlock mechanically but their enormous glue surface area makes them as strong as dovetails throughout the life of today’s modern adhesives.
Leigh’s versatile 24″ F3 Finger Joint Template is the most comprehensive and accurate jig of its kind. The F3 produces 11 sizes of square finger joints from 3/32″ to 1/2″ and the F3 can also produce three sizes of square half-blind finger joints.
The F3 Template has three comb sizes: 5/16″, 3/8″ and 1/2″. Each comb can produce joints in the comb size and smaller or larger joints. For example, the 5/16″ comb produces 5/32″, 5/16″ and 5/8″ joints. Similarly, the 3/8″ comb produces 3/32″, 3/16″, 3/8″ and 3/4″ joints. 1/8″, 1/4″, 1/2″ and 1″ joints are all possible using the 1/2″ comb. And that’s not all. Each of the three combs can produce unique square half-blind finger joints.
Leigh’s unique patented e-Bush, provided with the F3, guarantees a precisely fitted finger joint…every time.
Joint fit is easily and precisely controlled using Leigh’s patented e-Bush System.
Rotating the barrel of the e-Bush (left or right between 0 and 10) increases or decreases its active diameter. Each increment on the face of the guidebush equals a .002″ adjustment to joint fit. Using a setting between the marks adjusts joint fit by a mere 1/1000 of an inch!
The e-Bush is standard equipment with every F3. In fact, there are three e-Bushes included with every F3 Template, one for each comb size. All eBushes mount directly to many router bases. Some routers may require a Leigh template guidebush adaptor
