A basic jig that works well for 1/2", 3/4" and 1" material
Posted February 10, 2015
This product helps you make good mortise and tenon joints in material 1/2", 3/4" and 1". Once set up I was able to cut 56 tenons in less than 40 minutes. The joints are very good fit. Some care must be taken to ensure the width-of-tenon settings don't slip. I wouldn't recommend using thicker material with this jig even though it will adjust up to 1-1/2 inches.

Bought this jig since my primary requirement is to make mortise and tenon joints in face frames. i.e. no requirements at this point for angled tenons, which I knew this unit could not do. I've never bought a morise and tenon jig before, always made mortises with a mortise chisel press and tenons with a band saw. My main objectives with this jig were to reduce the time needed to make a joint and repeatability, both of which this jig achieved. In favor of this jig, the price has to be first with the ease of use and simple set up a close second. There are several points that are not obvious from the instructions or YouTube videos. Firstly, if you are routing anything bigger than 1/4" then you need to change the quide bush (not the bit) between mortise and tenon. It is fair to say that the interchangable guides provided make this a fairly simple task and it does not involve realigning the router base plate. Secondly, and probably the most annoying issue, is the amount of material that has to be cleaned from the tenon, which increases the wider the stock is. Putting a tenon an the end of a 5 1/2" board left almost an inch of wood to be removed from the ends (back to the bandsaw). Obviously, the videos showing this tool use carefully selected stock of just the right width to leave a clean end. Finally, there is no way to adjust a loose or tight tenon, since all cuts rely on the bushing and tool diameter sizes. I cut a 1/2" joint in 1 1/2" stock with two different 1/2" spiral bits and did see a difference in the fit, one was good, the other a little loose. Maybe Mark II could allow the tenon guides to move backward and forward as well as left and right to allow minute variations in tenon width. I would also replace the stock clamp screws with some sort of quick release lever system. Overall, I would recommend this tool, since at it's price point, there is nothing to compete with it. Even with the tenon cleaning required it is still a lot faster and more accurate than most other techniques, and, as I said at the beginning, my two reasons for buying this jig (speed and repeatability) were both satisfied.
Not the greatest tool

Hard to setup, does not hold wood very well, and is way to hard to setup. In the end I used it to make loose tenon joints (and it was fine for that) as the tenon part of the jig was poor at holding the wood and getting the wood set to 90 deg. I would look at other options, got it on a killer sale so I'm ok with that.
