After 15+years of wood working I've started getting concave rip cuts on my tablesaw. The concave is ~.015" in the middle of the board, on boards that are more than 14-16" long. This happens consistently with hardwoods mainly red oak and walnut. The saw is a Delta contractor with a shop fox fence,a Forrest blade, a feather board, and NO splitter. The far end of the fence is less than 1/64 further out of square with the miter slot to avoid pinching. The blade seems square with the slot - as best I could tell using a combination squate. I've experimented with the amount of pressure by the feather board, hand position, speed of the feed... and nothing seems to make a consistent differnece. Any ideas on what the cause could be? Thanks.
