If putting holes in the wall was a game this shelf wouldn't net you any points. The image below is a very rough SketchUp
concept drawing of a shelf I built. The concept of "clamping" shelving between the ceiling and floor isn't original to me, in fact I've see several variations of the idea; this is just my variation. The point of this method of mounting shelves is - you get the shelf without the holes in your wall, the concept also lends itself to being placed where there is no wall (stud) support.Special Note: In the following steps I describe how I removed the lip from the flanges, if you'd rather not have to do this I've learned that Simplified Building can bore out the fittings for you (additional cost per flange).
