Joe, the Family Handyman magazine has put out a lot of articles on these over the years. They had plans for a workbench and shelf unit about 3 years ago that was really great, kind of an A frame design with the bottom open so you could clean under it. I ended up making 4 of them for various people. You might check their web site, www.familyhandyman.com , to see what they have. Another source is the plans links at http://wickswww.freeyellow.com/ .
