Leigh Super FMT Mortise and Tenon Jig


The Super FMT Does It All

With the Super FMT and a plunge router, any woodworker can easily produce the incredibly strong and versatile mortise & tenon joint with amazing speed and accuracy. The Super FMT's design is based on the original and incomparable FMT. The same great features produce the same great joints.

Simplicity is the Key
The Super FMT uses just one bit, one guide and one setup for every standard joint. It's that easy. There are no bit or guide changes to fuss with and the setup stays the same for both parts of the joint. Joint fit is easily adjusted for perfect results every time. Super FMT guides and bits allow you to create any size mortise & tenon from a tiny 1/16" x 1/8" to a massive 1/2" x 5".

Infinite Joint Fit Adjustment
Joint fit is easily adjusted with the left hand guide pin. Simply turn the pin up for a looser joint and down for a tighter joint.

Easy Angled Joints
Whether you are routing a 90 joint, a simple angle or a compound angle, the Super FMT does it all with ease. Chair building is very demanding and exacting and the Super FMT makes easy work of the compound angle joints found in many chair designs.

Multiple clamp positioning holes allow clamping of the workpiece at any angle in any position.

Quick and Convenient Sighting
The removable joint aligning sight makes sighting simple, easy and accurate!

Beauty and Strength
Mortise & tenon joints routed on the Super FMT are immensely strong and virtually indestructible. This centuries-old joint is the thoroughbred of all woodworking joints and is used in fine furniture and cabinetmaking everywhere. See how easily you can make tables, chairs, chests, cabinets and stunning pieces like the rail and style bedside table below.
