Nick,
I don't have a slot mortiser, but I do mortises for Loose Tenon Joinery with a simple router jig and a plunge router. I have info on my web site describing the jig and how it works.
The jig is pretty simple to build and works well. The best thing is that if you have a plunge router, an edge guide and some scrap you can build this for next to nothing.
If you really want the router (or at least its base) fixed for this operation try searching for "Horizontal Router Table" as that's often what is used to do mortising with the router.

I converted an old Shopsmith into a slot mortiser. I used some 8020 inc. extrusions and linear bearings to make a sliding table. I use end mills for cutters and it works great.

I'm sure that you are not going to make this one but, you can have a look here

I don't have any plans but here are som pics of the one I made. It uses an old PC router table I outgrew and some modified bb drawer slides and a press screw for height adjustment.
I made a simple fixture that just fits my plunge router. It works great. My only issue was figuring out how to stop breaking those $20 bits. Once I solved that problem I haven't broken a bit since. I will see if I can snap a picture or two later. My fixture is out of 3/4" plywood....

Joe -
Nice set up. Can you post a photo of the back showing some detail of the height adjustment mechanism? I too have a PC table that I outgrew.
Here you go Tom I also put in a better shot of the x/y tables.
Thanks Joe.
Tom
Tom if yu get going and have ny questions let me know. i did modify the fence brackets to revsese them to attach the table to to the base and allow for the z adjustment.
I have the Taunton Book "Tables and Chairs" and there is an article in there by Ross Day and he uses a mandrel powered by a motor and belts and pulleys as his slot mortiser. Best design that I have seen that isn't a piece of iron.
Morris Tool is a good source for bits.

here is a link. I don't know if it is okay to post it, or if it will take you there, but there is a picture of the mortiser (do a search on the book when you get to this link for Ross Day and page forward until you see a picutre of the mortiser)
