I'm kind of new at digging into the "Why's" of vertical hammer hanging.
I noticed that an action I'm working on, the hammers have a rake of 88 =
degrees and a shank height between butt and underside of hammer moulding =
of 88mm.

My question is, "Is there a relationship between rake and shank length, =
or are the 88s a coincidence?"
I know the strike point is the important thing, but I wanted to make =
sure I wasn't missing a "Why".

Thanks in advance,
