Add even more versatility to your Leigh Super 18 Jig with this precision template. You'll be able to rout an additional six sizes of finger joints; 3/32", 3/16", 3/8" 1/8", 1/4", and 1/2". Two more sizes, 3/4" and 1", are easily produced by following a procedure in the User Guide. Plus, a Leigh Technical bulletin includes instructions to route double and triple size joints, all with the same incredible accuracy. That's 12 sizes in all, with just one template! Finger joints cut on a table saw or other tool seldom fit properly. But with Leigh's patented elliptical guide bush technology, you're guaranteed a perfect fit every time. This template comes complete with two Elliptical Template guides; one for each comb on the template.
