I have read that you can support a granite overhang (such as a bar) using 1/4" steel bars below or embedded in the rough top.
The purpose of this is to support the 16" overhang without using corbels or posts which get in the way of barstools.
However, given the 3/4" MDF rough top, I find that the 1/4" steel bars are more flexible than the MDF.
My intention was to use a power planer to cut channels into the rough top, then to epoxy the steel as bracing into the MDF, as shown in this example photo (not of my actual install):
But will this actually give me any more support? Am I just gaining tensile strength for the MDF?
