Thank you all for your responses and links to reference material.

Thank you - in this latest incidence, the instructor was taking a light cut consistent with the instructions ~.01" and took more than 90 seconds to complete the pass, then repeated the process.   The TT-50 indicates that a heavier cut can be taken (.03").   I will experiment with different depth of cuts and grinding times on the wheel exhibiting the anomaly after spring break.

I run the shops at Palomar College and we have 8 Tormeks in our shops here.   A question has come up regarding the helical striations that sometimes show up when truing up the grind wheel (see attached photo).   The grooves associated with the striations are significant and may affect the performance of the stone during the sharpening process.  Note that these striations appear regardless of how slowly the truing diamond is run across the wheel.   Could this be a defect in the stone?
