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?
