Support for overhang on granite counter top.
Having read a number of threads, I am somewhat confused on how to support the overhang of my granite countertop. I expect to create a bar area overhang of 12 or 13 inches. I intend to support the whole countertop including the overhang with 5/8 plywood. The granite will be 3/4" thick. I don't want to do corbels. Does my fabricator have to provide some sort of rod support?
