Ok, although you could save some money if you used Google.

I built a rig that not only mortises, but tenons, dovetails, and about
any other kind of joinery you might want. It took a couple of months of
part-time effort, but seems to work passably well. I have a few photos
at the link below. Drawings were posted to
news:alt.binaries.pictures.woodworking before I actually started
building - and may still be available in one of the archives.
