[CAUT] 70's St. B strike point

[Delwin D Fandrich]

The V-bar should have a curve to it. It's just that they sometimes got the
curve wrong and sometimes they put the whole thing in the wrong place. In
these cases we have to set the hammers in or out to compensate. 

The exact hammer strike point is not all that critical from the bass through
the tenor. It becomes increasingly critical from the top of the tenor
section up to C-88.

I understand that the strike 'line' in this piano should probably be an arc.
The capo certainly is. Referencing a straight line from note # 52 - #88 -
the capo arcs out 10 mm. at note #69.

It's the placement of note #72 that I'm really searching for. I have the
WN&G tool and I've moved the hammers in and out to find the right spot. My
ear agrees with their tool. 

Assuming I bore as usual and don't rake the hammers, if I were to hang
hammers #72 & #88 = 5 1/8" out from the flange center, put in the bass end
block, then pull the treble end of the keyframe out until #72 is correct,
then the treble end of the keyframe is 6 mm. proximal of the proximal edge
of the keybed and hammer #88 is 2mm. closer to the capo than it should be.

Any guidance?

many thanks!
