I believe David and others are asking (as am I) exactly a ratio of what = measurement to what measurement. Hammer weight to shank weight? Hammer = length to shank length? Are you speaking of the standard Center Pin to = Knuckle Core and Center Pin to Hammer Center? If so, are both these = measurements taken along the same line? Or are you measuring from Center = Pin to Knuckle contact point and Center Pin to Hammer tip or somesuch. = Maybe this is a Stanwood-type weight thing? =20 > Hammer shank ratio. Last chance.
