My cabinet vendor installed a really cool 5 sided, 12" deep cubby(shelf) below my upper cabinets. It's laminated 3/4" plywood. The problem is that it's 84 inches long and there already is a very slight sag in the middle and I haven't even stacked anything in it yet.
One option my vendor suggested is to put a couple of floating braces underneath it (like this but less heavy duty. I've found some that are 3/6" thick). The part attached to the studs would be buried beneath the drywall/backsplash. The problems is that the supporting arms beneath the cubby would be visible from a number of angles. (My architecture and interior design is modern and streamlined.)
I asked if the cubby could be notched on the bottom so the arm would be flush and then have laminate adhered to the arm to make it less visible. They said that it wouldn't be possible. But based on all of their suggestions it seemed like they just wanted to go with the most simple solution available.
Given my specs would my notching solution be feasible?
