In this episode I introduce Leigh Industries’ FMT, their flagship Frame Mortise & Tenon (M&T) jig. This is the latest tool in our shop.

Why the FMT? Because it excels at cutting mortises and tenons with high accuracy. With this jig we have the following options:

  1. Use the FMT to cut all integral tenons and mortises for a project. The result: Perfect-fitting M&Ts.

  2. As an alternative, cut all the mortises with the FMT, and also shape long tenons with the FMT. These tenons are then cut off on the table saw, to make loose tenons. The result: Perfect-fitting M&Ts.

  3. A secondary alternative: Use the FMT to cut all the mortises, and cut loose tenon stock on the table saw, followed by shaping on the router table. With this option the loose tenons may require some “shaving off” and tweaking to optimize the fit.

I have confirmed that the versatility, simplicity, and the ease of use of this jig was the correct decision for me. The best way I can explain this is as follows. I need to make only one layout for the mortises, and one layout for the tenons; I then select one router bit and its matching guide, and make test cuts to confirm that my layout is OK. From this point on I can make as many tenons and matching mortises as I need for a particular project.

About Me

My name is Al Navas, and I live in NW Missouri with my bride of many years. We are both woodworkers who love to be in the shop together, sharing wonderful times. She is a woodturner, and also carves and does pyrography. I do what many call flat work, which includes jewelry boxes to blanket chests; armoires to entertainment centers; church altars to prayer kneelers; custom cabinets to rustic furniture. In our “spare” time in the shop we make toys, bird houses, etc., for our granddaughters. In late 2007 we finished serving as officers for the St Joseph Woodworkers Guild.
