The magic of engineering that is. Where ultra-light construction and a wall attachment trick create a seamless illusion. o ahead. Take a guess. Just what do you think one of these shelf units weighs? I'll give you a hint. The thickness is 13/s", the length of the longest part is 78" with the other leg 61". The height is 24" and the depth is 11". Some serious cherry timbers, you think? Say 40 or 50 pounds? Well, guess again friend 'cause you're off by a factor of two. Yes, 23 pounds for the big unit and just 20 pounds for the smaller one. What you're looking at are three torsion boxes for each unit that use a solid cherry front edge, a top and bottom of V4" cherry plywood and several pine ribs that run cross grain to the cherry ply, or perpendicular to the front edge. It's all glued together to make a strong, flat and lightweight panel. So how is it fixed to the wall? I'm not revealing that trick until the second act! And by the way, if you think you've seen these shelves before, chances are you have. Our version was inspired by those shown in an Ace Hardware advertisement. I wasn't surprised to learn from Ace that they'd had hundreds of requests for plans to build this project. When I suggested we feature it here, they jumped at the chance. by Steve Shanesy |
