You can’t turn the platform backwards after it contacts the diamond. That will give a false reading. What steel are you using, 10i5? That has a maximum hardness of about 65.

Hi Loz, can you share your view on the benefits of multiple tempers vs. a single temper. How big a difference does the additional tempers make? Thanks mate, cheers.
