[CAUT] duplex position

[David Ilvedson]

I phoned Steinway and talked briefly with David Kirkland(spelling).   He didn't have specs below 1905 but he said the duplex position was of little consequence.

At our last chapter meeting we were discussing duplex scales and whether they made a difference and so on the B that Dale has exhibited we muted different segments and listened. Bob Davis did say that the duplex is tuned to the fifth so he strings the two end wires in the section and sets the duplex bar according to his ear. We plucked and the duplex scale was on the fifth where Dale had set it.

Hi David. 



Happy New Year. 



Here are some measurements I got from Greg Hulme in KC.   



Style B  measured from duplex to rear line of bridge pin 

Note 40 = 98mm 

           51 = 46mm 

           52 = 85mm 

           68 = 37.5mm 

           69 = 46mm 

           88 = 25mm 



Hope this helps!

Subject[CAUT] duplex position



  















List, 

  

Is there a clear cut way to position the duplex bars on a Steinway?   This is 100 year old B I'm restringing.   Top treble sections only.   I can position as I found it but is there a measurement from the bridge pins...?
