I am preparing to attach a piece of butcher clock (about 42" L x 18" W) to the top of a half wall that w recently built partially across the entryway to our kitchen. I'm trying to figure out the best way to securely attach the butcher block to the top of the wall, which is only about 5" wide. Attached a pic of the bar top being held in place.
From my research so far, it seems like my options are either corbels or steel brackets, and drilling up into the butcher block through the brackets or corbels. I was planning to use construction adhesive to secure the board to the top of the wall, but from what I've read glue is not recommended to allow the board to expand and contract (otherwise can split/crack).
Any advice on whether the brackets/corbels will be enough, or if something else is needed to make sure the cbar top is secure? ('m sure ideally attaching the butcher block before finishing the half wall is ideal to secure it from the bottom - though at the same time wouldn't be able to mount the brackets). Thanks in advance for any suggestions.
