I am going to make a kitchen table of quarter sawn white oak (5/4).  I have glued up and flattened panels for raised panel construction and smaller table tops using an orbital sander.  I am wondering (and concerned) about what the best bet is for ensuring that a large surface such as a kitchen table (48″ circle w/out leaves; with leaves, 48″x 72″) that will be highly visible is flattened with no or minimal raised surfaces or valleys.  Thanks.
