Leigh Multiple Mortise and Tenon Attachment for D4R Pro Dovetail Jig

M2 Multiple Mortise
& Tenon Attachment

Fits 24" D4R Pro, D4R, D4, D3 and D1258/R Dovetail Jigs

The layout and routing of multiple mortise & tenon joints demands such a high level of time-consuming care and craftsmanship that these striking joints are usually found only in the most sophisticated hand-made furniture.

Leigh's M2, Multiple Mortise & Tenon Attachment however, brings this challenging joint within easy reach of any woodworker who owns a D4R Pro or D-series Dovetail Jig and a plunge router with 1/2" collet. The M2's adjustable guide fingers let you rout multiple mortise & tenon joints in virtually any layout you like, in stock up to 24" wide. Mortises & tenons can be routed in sizes from a delicate 5/16" x 5/8" to a muscular 1-1/2" x 2-1/2".

Jumbo Joints
As if it weren't enough for the M2 to produce fine multiple mortise & tenon joints, it goes one step further, routing extraordinary jumbo variably spaced finger joints. Finger Joints are almost always made with identical finger and socket sizes, but since fingers are basically multiple tenons and sockets are simply a series of mortises, Leigh's M2 is a Finger Joint jig right out of the box. The M2 makes fingers 5/8" or wider, symmetrically or variably spaced, just like Leigh dovetails. The M2 handles stock as thick as 1-1/2".
