With that in mind then I guess they both use the same templates? With the Super being discontinued I was wondering if it would be difficult to get parts that wear. But if they use the same parts then I'd guess not. And I'm also guessing bits can be had by many vendors but maybe special bushings? Just trying to see what might be the problem down the road.
There isn't much to wear out. Yes, the templates are the same. Only a very smooth slightly tapered pin rubs on them and they are a hard plastic. The pin rotates via a knob on top and this lets you make very fine size adjustments of both the mortise and the tenon being cut, so you can get the perfect fit desired. I think this one inovation makes the FMT jigs superior to every other jig on the market
The bits used with either FMT jig are standard spiral up cut bits available from many sources.
Bushings? There aren't any. The top guide plate that the router attaches to has two steel pins sticking out of the bottom of it. One steel pin in the right side slides back and forth in a close fitting plastic guide. The pin on the left is the tapered pin with the knob adjustment that I mentioned above. You follow the plastic template with this pin and the top plate moves the router, kind of like a pantograph does as the router cuts the mortise or the tenon. You follow the outside of the template when making the tenon, and the center slot of the same template when making the matching mortise. It's located on the front left of the top of the jig and not located anywhere near the router bit.
There is an alignment sight that slides into position with cross hairs that you use to position the work location for each mortise or tenon. When making more than one mortise or tenon, you only need to use this sight for the first piece setup. Then every identical piece can be cut without the sight. The design of the top plate prevents you from damaging this sight, so you have to move it back out of the way before you can rout. The top of the jig slides X and Y and has a position lock, so you can align the cross hairs to a mark on your first part. This sliding top plate also has adjustable stops, so you can set up to four locations when you want to make a group of up to four mortises and tenons. Once set on the first part, you just slide and lock this X-Y table from stop to stop and rout each mortise or tenon. You do both the mortises and the tenons with the same setup, so the fit together perfectly when completed. Again, no other M & T jig that I know of has this feature either.
The FMT jigs cut mortises and tenons so perfect and beautifully that it's a shame that they won't ever be seen after the project is glued together. I have make them in scrap pieces to show my clients what the inside of their joints look like. Otherwise they never have any appreciation for the quality.
