Innovative FMT Features That Benefit You 
Perfect Multiple Joints!It's remarkably easy to set up perfectly aligned multiple mortises and tenons on the FMT. Precision and repeatability are made possible by adjustable table limit stops (circled here and below) that control the table's range of motion in both X and Y axes. With each mortise or tenon position sighted and limit stops set, you're ready to rout double, quadruple, or even triple joints with the same ease and precision as a single mortise and tenon. Double and Quadruple Joints The sequence below shows each step in making double and quadruple joints. In steps 1& 2, the side-to-side limit stops are set to produce double inline tenons. Steps 2 & 3 set the front-to-back limit stops which are used to produce side by side tenons. Clockwise from left, examples 1 to 4 below show how a quadruple tenon is routed.  From the above sequence, it is also easy to see how double joints are routed – either side by side or in line.  Triple JointsTriple joints are set up just like quads. Make a small stop block to fit between the front-to-back limit stop and post (circled), to position the table for routing the third mortise and tenon. Wider or Narrower Joints 
It's always faster and easier to use a joint guide made to cut the exact mortise and tenon size you want. However, if you don't have the right guide on hand, or if you want to cut a joint that's wider or narrower than the nearest guide size, you can use the table limit stops to change what any given joint guide allows you to do.
In the photo above, a single 1-1/2" joint guide (1) has been used in simple two-step procedures to cut a 1" wide tenon (2) and a 2" wide tenon (3). You can cut tenons as short as twice the diameter of your bit, or up to almost twice the guide length. The photo above shows that with a 1 1/2" guide (1), a simple two-step procedure is used to rout either a 1" wide joint (2) or a 2" wide joint (3), or any width you choose from; up to nearly two times the guide size or as narrow as two cutter diameters. Production Routing and Smaller Joints When you're engaged in a high-volume production job, you can speed up the process considerably by using the largest bit possible to cut tenons smoothly and quickly in one pass. Using a tenon bit larger than the joint guide size will make tenons that are smaller than the guide, so you'll have to use a bit smaller than the guide to cut matching mortises. The principle is simple: any two bit diameters which add up to twice a given joint guide size can be used to make joints the size of the smaller bit. (See drawing at right.) In the extreme, this technique lets you cut joints much smaller than the FMT's smallest 1/4" joint guides. Delicate furniture parts such as small cabinet door frames, doll house architecture and furniture, and very accurate miniatures all call for mortises and tenons as narrow as 1/8" or even less. The charts on pages 12 (inch measurements) and 14 (metric) show how different bit combinations can crank out such extraordinary joints just as quickly and precisely as larger ones.  This diagram shows how a 3/8" x 1" joint guide can be used for rapid production of 1/4" x 7/8" mortises and tenons. A strong 1/2" bit quickly mills tenons 1/8" narrower and shorter than the guide; a 1/4" bit cuts mortises correspondingly narrower and shorter as well. Incredible Miniature Joints are Easy!

The FMT can rout joints not just smaller than 1/4" but so tiny they're almost beyond belief - all with the same easy setup and adjustable fit you expect in larger joints. These examples of miniature joints show the extreme versatility of the FMT. The 7-1/2" ebony and holly ladder leaning against a 1/2" X 5" tenon has ebony wedged tenons 1/16" X 1/8".
