The hammer shank ratio, then, is determined by the distance from the center pin to the knuckle core center. Where you place the extra gram of lead on the hammer shouldn't make any difference.

Hammer shank ratio.... What range of things could I possibly be talking about here eh ??? The hammer / shank / hammershankassembly.... it constitutes a lever and a load... or just a lever depending on your point of view... ( I take the former and not the latter). One with two ends and a fulcrum... class three lever .... force applied between the load and fulcrum..... Hammer shank ratio. RicB David Love wrote: > I'm still not sure what you mean.
