Hello list, I have an oddball question- How wide is the span between
the centers of keys #2 and #86?

I am building a special leveling bar to go across the keyboard, but am
having trouble setting a third foot in the right spot so that the
straight edge can rest on the sharps as well as the naturals without
tipping over.  I need to know what the shortest and longest distances
between the center of the sharp keys are.  
So far from local technicians I have gathered that from center to
center, the sharps measured anywhere from 44-15/16" to 45-3/4" on a
wide variety of pianos from different manufacturers and eras.  Do you
measure anything  greater or less than these on your keyboards?  

Respectfully,
