I use my stone grader diagonally on the wheel, and rotate it frequently which avoids it getting dished. it is being run against a grind stone, only takes a fraction of extra weight on one end or the other to start dishing it on the edge of the stone. By keeping the grader  diagonal and rotating it this helps keep the grader flat.

For the other part put a straight edge behind the Tormek about 3mm gap to the wheel, shine a light down and watch you should be able to see if the rotation is true.

Earlier in this topic a question arose about whether a tool is carbon or high speed steel. Using your high speed grinder, a quick spark testwill tell the story. Here is a link:

A quick search will show several videos.

And it is helpful to keep samples of known composition by the grinder for comparison purposes.
