Hi all.. I'm a relative newbie to woodworking. I'm attempting to get some dimensional lumber out of some live edge stock I had. The pieces are about 6' x 2' x 2.5". I've managed to flatten both sides using a router jig and a belt sander. My question is: how would I go about making this stock square so I can get some dimensional lumber from it? I do not have a jointer. I do have access to a table saw. Thanks!
