At the local hardware store I noticed various floating shelf designs. Because there are no visible brackets, this shelf support system is sleek and uncluttered.
For a wider shelf to work, the backing plate against the wall had to be harder than the soft pine typically used for layout benchwork. The soft wood could work free from the mounting bolts. I also needed to minimize the shelf’s weight, while making it rigid enough to resist warping.
After some experimenting, I found a combination of materials that’s lightweight, stable, and visually clean. My floating shelf benchwork consists of a poplar backing plate, select pine outriggers, an extruded-foam benchwork top, and wood lattice fascia. Follow along as I describe how to build this sturdy and professional-looking shelf layout benchwork.
