If you've already taken the beech shelves, you can salvage them by drilling a suitable sized hole in what will be the underside, fill them with silica sand and plug the hole with with a chunk of dowel and some wood glue. Sand, stain to match and lay on a couple coats of Minwax wipe-on poly. Voila! Instant shelves...
