This post was brought up because my mentor, Dale Erwin, was having to raise the stack on an O that was one of the very first ones. Almost a prototype. He didn't know of a wippen pin height and wanted to. I was suggesting the stack might still need to be rotated since the cushion/shank gap was way too much, even after the raise. After the raise, the hammer pin was a mm higher from the keybed and the wippen pin was 83mm. The stack can't go much higher no matter what the spec is from the string plane because the tops of those huge roundtop screws need to be ground off as it sits. However, the stack could rotate the wippen rail up to solve the CAF without raising the hammer pin. The string plane is not good on this casting.
