[QUOTE="Oldhoopster, post: 3811410, member: 84179"]And machine doubling is not considered an error/variety because...…? (don't answer "because it's not hub doubling", we know that) ;) Playing devil's advocate, if MD is caused by a loose die shifting during the strike due to inattention of the technician, equipment wear, etc, then why would a weak strike be an error if the planchet that meets the thickness spec? Wouldn't that be due to operator/equipment non-conformances as well? :troll: Remember, I posted that I don't think MD should be classified as an error/variety. I also believe weak strikes are an error, but I'm enjoying the discussion so far. Can someone come up with a convincing argument why Chris and I are wrong?[/QUOTE]
