We have a fairly large living room space. it's about 19.5' x 22' and I want to build a long shelf above the television to display some large models. I'd like the shelf to be 10' long by 20" deep.
My plan was to use a 2x4x10 and toggle bolt it to the studs on the wall, then build off of that 2x4x10 with 18" 2x4 struts and then finish it with drywall. The total weight of the models on the shelf will be around 100lbs.
I can't find a lot of information on extra large floating shelfs online...most of what I find are pre-fab brackets for very small floating shelfs. Is this because it's not going to work? I am concerned that if I go too deep with the shelf that the front edge of the shelf will droop and not stay perpendicular to the wall.
