I have some beautiful 10-12" wide, approx. 1" thick cherry boards (almost entirely clear heartwood). I'd love to use them to make a tabletop for a dinner table (probably something in the dimensions of 2.5x6 feet), but I'm concerned about making a tabletop that size with a finished thickness in the range of 3/4". I'm considering running supports between the aprons underneath the tabletop and attaching them to the tabletop with the same buttons or figure-8 washers I use to attach the tabletop to the aprons. Is this likely to be sufficient to stiffen and support the tabletop? Anyone have suggestions for working with thin tabletops? Cheers!
