Ray, it seems that the piano hinge is the only option and not one I had in mind. My minds eye can see my desk open with two brass hintes with rounded edges countersunk into the surface. When looking into various catalogs including White Chapel I can't find anything that will work. The article in White Chapel stated there wasn't a hinge for this application and that people on the years managed to use the desk and work around the hinge that came above the surface of the desk. Thanks for the links, I saved them a favorites for future needs.
