EDGE RETENTION/ROLLING PART II

[EOU]

Well there you go again Larrin, another interesting approach. We're fairly convinced that there should be some measurable difference between HRC50 and HRC62 (if for no other reason than that the supporting metal is more, or less, brittle) but confess that the only evidence we have of that is based on some pretty loose indicators. First and foremost of those indicators is the fact that non-hardened steels seem to produce the mother-of-all rolls. Even with 150 grams, perhaps we could readily see the difference between, say, HRC35 and HRC54. Anyway, use of a stream of air or a lighter weight might enable us to see these less significant differences, assuming those differences exist. 

Jan your proposal is not only digestible but exactly in line with how we envision the measurement process unfolding. We don't know that for certain but it makes sense until we learn otherwise.
