T-Nuts for Granite/Plywood table?
I have a 36" X 68" kitchen island top of 3/4 granite . It simply rests on the frame work of the island, basically 3/4 plywood on edge with cabinets and drawers like typical kitchen cabinets. There are some cross members of 2" wide 3/4 plywood. The granite is loose and can be moved. I was going to do something more sturdy but have not gotten to it in 25 years. I have stood on it a few times , I keep my feet over the 3/4 on edge plywood. A good finish carpenter made the island so it is very flat. So cabinet type birch plywood should be enough.
