- It doesn't make that much difference. You also can't be certain that
blank diameters are completely consistent through the years. All that
matters is that the relationship between blank thickness and blank
diameter enforces the same narrow weight tolerances. Naturally, blank
diameters will have to stay within a fairly narrow range, but absolute
adherence to a specific diamater is not necessary from a production
