[pianotech] Baldwin Front Duplex

I don't believe that's the speaking termination point.

Subject: [pianotech] Baldwin Front Duplex

Hello list,

I just have a curiosity question. I was tuning a 1999 Baldwin SF today and
was noticing, what I thought, was an oddity of the front duplex system.  

If you can see from the picture, some of the duplexes are wider and the
speaking length starts a little more back than the others. Surely, this has
some affect on the scaling and such, but what seemed odd was that in the
first section of duplexes, there seemed to be no pattern of how they were
set, wide versus narrow.  It just seemed like a random placement to me.
(Sorry, the picture doesn't show the full section. I was trying to get a
good close up to show the difference in the duplexes).

In the 2nd section of duplexes, (the high treble) they were all the same,
narrower ones and the start of speaking lengths seemed to look more uniform.


Did Baldwin have a reason for placing the duplexes in such a seemingly
random way?  Or does it even effect the scaling design with such a nominal
amount of distance difference that the duplexes were just placed in whatever
fashion they were placed?

Again, just curious. The piano tuned fine, with whatever rendering problems
most Baldwin grands have. :-)

Thanks.
