Hi Harry,
I've revised my design a couple of times and I think this is my favorite. I built my own lift, based on some others that I have seen. I like mine because I can raise the top and quickly change cutters without ever removing the router.
If you're interested, the plans are available as a free download, complete with step-by-step photos, captions and technical drawings. Go to Popular Woodworking's website, click on projects, then click on shop, then scroll down until you see "click here for complete plans" pdf. It's called the deluxe router table.
I welcome any suggestions as to how it can be improved, altered or whatever.
