One other advantage in granite is that if you do drop a hammed on it it will chip rather than dent
I would think this would be quite noisy. I have used corian on a router table top and though it was nice and flat and heavy it resonated noise quite a bit. I like the idea of using it for a jointer fence though.
I can see where the corian might resonate, but Granite is rock. I wouldn't think it would resonate to much. Not any more than a cast iron top.
Marketing and the designers were definatly thinking outside the box on this one. There are some good advantages here but I feel the novelty factor would wear off within a year or so. It wouldnt bother me at all to be wrong about that.
I'll be soon looking to upgrade to a better saw and have been thinking a hybrid saw. Im hearing very good things about Steel City and plan on giving them a close look, and this option will be out by the time I start looking. Sooo :eusa_thin will have to take a close look.
