Kenny, you can't go wrong with wood from Spanky, it's all furniture grade, all Tennessee hardwood and we're not that far away from you. Welcome to a great forum. Lots of info here with all the help you could ever need.
One trick we boat builder's use is to place a small chunk of end grain is a small saucer of rubbing alcohol. If it is Red oak it will immediately suck up the alcohol through the grain and by capillary action seep out the topside of the piece. White oak is much more tight and will not do that so readily. Try it, it's kinda fun to watch./
Be glad she didn't want to have two leaves in it. Going to work on a table for SWMBO soon...been on her mind for about 5 years. Now that she is retired, I can use the extra hands in ripping, planing, assembling and finishing. I want to put in one leaf at least as we can have as many as eight people at the table. The little kids sit at a card table.
