I got a little time today to work with the Mortise Pal.... NICE
It is made very well, for those that have a DowelMax, it is right there with it and works as advertised.
I did find that I don't like the knob that is used to tighten the jig on to the wood, it just doesn't feel right for some reason and it could be larger.
Just like the video, mark the center and were you want the mortise and set the jig on the wood. Line up the marks and clamp it down, couldn't be much easier. http://www.mortisepal.com/videos.html
With narrow boards its still no problem, just put a shim in to clamp with the small board. I was using some 1/2" boards and I used a 3/4" board for a shim, you are still moving the center of the jig to your center of the mortise.
The mortise is clean, that is if you have a sharp bit. The one thing is the templates are about 1/32" wider then the bushing. What this means is if you don't hold the router to one side or the other your mortise will be wider then the bit.
This is really no problem if you are planing and making your own tenons, which I am. So I will always plunge the router the lenght of the mortise and then clean up by routing to each side of the template.
One of the things that surprised me right off is the fact that you loose 3/4" of your router bit. That is the bushing and the center of the jig take 3/4" and I did have to pull my bit out of the collect more then I normally have it set.
Its not going to replace a bench top mortise machine, a Domino or my DowelMax but for me it is a great addition to the shop.
It is still on sale on their site until the end of the month.
