Mantle building opinion needed
I plan on building a mantle for a family member soon; it'll be mounted with a 2x french cleat with attached vertical 2x members to mount the corbels. The mantle and corbels will be hollow construction and no cleats will show. This will be on natural stone. I've been building and woodworking for a long time but find myself dreading this because I feel I should at least attempt to scribe and fit into mortar joints and allow for stone surface fluctuations.
Is this something I should attempt and is it worth the extra aggravation? Or is it okay to leave gaps? Thanks for all responses.
