I tried a few different jigs where the jig's baseplate is clamped on
top of the wood to be mortised. The challenge is always to get the
baseplate either securely clamped to the wood, or have it slide evenly
and still remain in tight, square contact. None of these designs
worked well (and it did limit the depth of the mortise.
In the end, I chose to clamp a sandwich of the work piece and two
boards in my vise. I made sure the two side board were flush with the
top of the work piece. This sandwich provided a wide enough base so
that I could use the router's edge guide.
I was making loose tenons for the apron of a table, so the design had
to allow making mortises in the end of a board.

Does anyone use this jig? If so, how does it work for you? <snip>

It's simple enough, so why not just make one, try it, and see if
you like it?.

I do, and it works very well and is uncharacteristically simple for
that magazine's jigs. It's cheap and easy to make.
Two edge guides on the same rails work just as well.
I built one and it worked great. I made a few modifications but the
only one I can recall is that I beveled\chamfered the inside face of
the guides leaving only 1/4" flat at the upper edge so I minimized the
drag on the 4" wide legs I was working on. My test runs showed that
once I had the fence tight enough it would easily bind and having less
mating surface made the jig slide a lot easier.

I made one some months ago. Works for me. You need to tighten the hell
out of the wingnuts securing the guide bars lest they slip. Was I doing
it again, I'd go with transparent plastic for the base plate. Makes it
easier to see what you are doing. The jig keeps the router bit tracking
down the length of the mortice. It's easy enough to stop routing on a
pencil line marking the ends of the mortice.

For the OP ... Tage Frid still has one of the most elegant designs for a
mortise jig in the face of stock:
http://www.highlandwoodworking.com/library/tagefridsmortisingjig.pdf
... and for mortises in the ends of stock, the second one on my jigs page
(scroll down to Router Mortising Jigs) is hard to beat:
http://www.e-woodshop.net/Jigs.htm
A pdf of the plans is available at FWW, but you have to be a member to
access it, IIRC.

You did not ask but here's another router jig option:

Not all that impressed with it. Basically, you can do the same job that jig
does with a good edge guide for your plunge router, and with a lot less
fuss.

Not too fond of the design, just because it pinches the work, *not* pinching
it would result in slop in the joint. Seems like an edge guide would work
just as well, but if you go that route (har!), be sure to route the side of
the mortise away from the edge guide, so any slop is routed away in pass #2.
