I am “building” a simple trestle table. The base will be two metal trestles with a stretcher extending between them. The top will be 72″ X 42″ and will be quartersawn red oak, approximately 1″ thick. No breadboards or apron. Will this be fine with the assembled top attached to the trestles, which will mean that the outermost boards won’t be supported at all? Or should I add some other support under the tabletop that extends across all boards?
