   It isn't a problem unless you are doing work that requires exceptionally accurate cuts, such as fancy joint making. Almost all low to mid price saws and a fair number of the more expensive machines have slightly warped tops, typically some sort of dishing toward the center.

   There is no fix for the problem, there's nothing to adjust at any rate. A replacement top would almost certainly show some warping also.

   JohnThanks for the reply. My dish is exactly where you suggest, around the throat. I also contacted Delta and was told that the top was "within specs" which is .010". This was a little disillusioning to say the least since all the set up articles and books that I have don't mention such a wide tolerance. In fact, they talk about how flat the top has to be.In use, the dish doesn't seem to make much difference, except in getting the throat plate flat. I checked my cuts with a machinist's square and they are square. I think that, to some extent, the wood may be bridging the dish, so it has less of an effect.Right now I am just at the building cabinets level. If I start making furniture with highly precise joinery, I will buy a better saw.
