Well, I finally got around to tiling and grouting the backsplash in our kitchen. This leaves one last project to do- installing the breakfast bar on the island. The island is a bank of three base cabinets (2 30" and one 24"), that are attached to a 42" half-wall. From the countertop to the top of the half wall is tiled, and there are 3 electrical outlets installed. The top of the half-wall is an exposed 2x4, and the side opposite the countertops, and edges of the half-wall are finished with drywall.
For the breakfast bar, I have purchased a solid 1 5/8" thick wood butcher-block countertop, that I'll rip down to overhang 1 1/2" on the countertop side, 1 1/2" over the half-wall edges, and 14" over the back side of the half wall. My primary question is- how do I attach it to the half wall? Is 14" too far for a 1 5/8" butcher block to overhang without support? (i.e.- do I need corbels to support the bar?) How do I physically attach the countertop to the top of the half wall? I am guessing my finishing of the half wall is going to nail me here :(. I have thought about using keyhole plates routed into the bottom of the butcher block, and heavy screws with large heads out of the top of the half-wall. Is this reasonable? Any insight would be greatly appreciated!
