I own a 2412 and noticed that the stamped steel extensions are warped, particularily the one on the right of the blade. Is this something that should be covered under warranty? I am thinking of purchasing one of the cast iron extensions that the 2424 uses. Would it fit my saw? I've already bought the 2424 rails. I got a good deal on them from my local HD so I decided to buy them to increase my cutting capacity. It was when I was trying to relevel everything that I noticed the warpage.
