<p>[QUOTE=&quot;Conder101, post: 4878121, member: 66&quot;]I would think if you were rockwell testing a die blank, you would testit BEFORE the end of the blank was turned in the lathe to create the cone pressed against the hub.&nbsp; You would test near the edge of the blank and then the subsequent lathing would cut away the tested area.&nbsp; No trace of the test would remain on the blank when it was ready for hubbing.&nbsp; And then after hubbing even more of the edge of the die body is cut away[/QUOTE]</p><p><br /></p>
