I know this is an old post but thought I would mention that the saddle issue on the Tormek CBN wheels is a thing of the past. So is the ringing problem that some people experienced. Our two new style wheels - the Spartan which has a nylon center and our Tornado which is has 1 inch of grit down the sides also are dead flat. We no longer make or carry the style wheel that had saddle issues. Thanks. Ken Rizza - Wood Turners Wonders.
