Having a problem aligning my Craftsman Rip Fence the miter slot of my Craftsman Table Saw. The saw is about 4 years old ( bought it new). Model number 315.228390, Rip fence model number is 315.22830. I have tried aligning with a dial indicator but could not bring it in. Also, are there any suggestions for a replacement fence for this saw that would achieve accurate cuts? Thanks, Larry
