   I would check to see if where the riving knife installs is actually in line with the side of the blade. I would measure from the front of the blade[fully raised] at the tooth set to the right, and measure to the miter gauge slot and then measure to the right side of my riving knife.

   It sounds as if your splitter (that's what most call it) is not perfectly in line behind the blade. If you take two edge-jointed boards, and put one on each side of the blade, just touching the teeth, your splitter should fit between them, and should touch the one on the fence side.

   I think that a splitter is what you call it on a Delta contractor's saw (like mine and yours). What makes a splitter into a riving knife is the ability to move up and down with the blade. The reason that's useful is that it allows you to place it immediately behind the blade with little clearance (1/8"), and there is no risk you'll hit it as you raise the blade. A splitter must be further back.

   If your splitter is in line and there remains a problem, it could be that you have wood that is springing out as you cut it. If that's the case, your splitter is working properly, and has prevented dangerous kickback. Use a half-fence if you must cut that wood. A half-fence is a board clamped to your fence that ends where the teeth meet the workpiece, and leaves space behind the cut.

   Cor, use an accurate scale to measure distance from the trailing edge of your blade and the riving knife.

   The knife edge may be closer to the fence. As I recall, I had to shim my riving knife for the same problem.

   Good luck.
