This is a table I built about two years ago. It measures 36"X89", 5" inch skirt, 3"x3" legs turned down to a little over an inch at the bottom. All the stock started out at least 6/4, rough sawn and air dryed, I'm not sure what it finished to but its at least an inch. It is very stable in that it is not wobbley at all. However I have had a lot of trouble with the bread board ends . The top seems to expaned and contract excessivley with seasonal change. I have already redone the ends twice. I dont know if it is just this particular cherry, but the last time I changed the ends I put full 1 inch slots in the tenons the pegs go thru and used no glue. Your top is even wider.
