Bought this jig since my primary...
Posted October 7, 2011
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.

I purchased the E-Z Pro Mortise and Tenon Jig to make my life easier. At first I thought it was a great tool until I got to the part of my project that I had to put mortises in my 1 1/2 X 1 1/2 square legs of a rocking chair. The clamping devise is not set up hold 1 1/2 or narrower material, therefore I had to revert back to the old way on a drill press. The two screw devises on each side for a mortise and tennon are time consuming and if not tightened alternately one end will bind up against the other. I was also disappointed and had to find out the hard way that there is no way to keep long tenons held perpendicular to the jig when routing, the hold down device is not sufficient enough to hold the peice from moving. This tool is an improvement over other methods but needs some professional use and refining. For some applications it will work fine but for my project I was only able to perform 50% of the total project need.

Purchased jig after reading advertisement which was my mistake. Quality of the jig is poor. Difficult to center and square wood on jig. Clamps are flimsy allowing wood movement during routing. Tenons have excess wood remaining that requires a good clean up. The comments in Woodsmith (vol. 34/ no.201 pg13.) were generous too say the least. "Knobs are cumbersome and too slow... Lack of reliable ray to square stock... alignment is difficult" etc. etc. I went to the trouble of modifying this jig as recommended in the article which was an improvement but still the jig is a challenge to use. To get it right it takes lots of patience and lots of practice cuts.
