I got the TS2412 with the stamped wings. What a pain. Wishing now that I wasn't so cheap and paid the money for the TS2424. The stamped wings are warped pretty bad. I can force the edge that bolts to the table saw to be level by bolting the middle bolts tight then forcing the ends down with c-clamps, but this doesn't help the opposite edge. I'm left with a big bow at that end, on both wings. I'm going to spend the money and upgrade to cast iron wings. Just wanted to know if anyone out there has ever put a straight edge to the top of there cast iron wings and checked for flatness? I can fit a .060 shim between the stamped wings and a straight edge. Does anyone know what ridgid's tolerance for flatness is on the cast iron wings? not going to spend the money if they aren't flat.
