Unfortunately, with a fence that is out 1/64”, you can never square up a piece of wood so it is a perfect 90°. Getting wood to a 90° accuracy is the most important dimension in woodworking. A miter gauge can be set to cut a perfect 90°, but when you rip it, the squareness is lost. I have the same problem with my Biesemeyer fence and I’m still trying to fix it. Maybe a torsion box structure attached and shimmed to the fence might work.
