Possibly...

But the capstans are so far off (I'm being pretty generous calling it 1/4
inch - its probably closer to 1/2) that if it was really an offset of the
stack, I think there might be some fairly obvious problems fitting stack to
case and frame, not to mention strike point - and that didn't seem to be
happening.

I'll be doing a lot more measurement and analysis when I return to this
piano in a few weeks (after my wife delivers our second child - any day
now).  That it might be a stack positioning problem would sure make it
easier to explain, given how the factory positions capstans.
