I am building a coffee table for a friends girlfriend and her housemates. I found a guy that has a sawmill and has a couple of oak slabs. I am going to see what he has this Friday. My design is pretty basic just going to make a 3 foot long by 2 foot wide table top with 4 legs and I think horizontal bars going around the perimeter to brace the legs. My problem is I think all this guy has is 2 inch oak slabs and 1 inch oak lumber. I want something thicker for the table legs at least 3 inch square. I am going to attach the horizontal bars with mortise and tenons. I am wondering if any one has a suggestion of a second wood to use as table legs. What wood would compliment the oak? I am not sure if it is red oak or white oak he has. My guess would be red. I believe he has red maple, ash, elm, cherry, and hickory as well as the oak. Would any of those compliment the oak table top? He also sometimes has random pieces of other woods that I could maybe use as legs. Let me know your thoughts. Thank you.
