[pianotech] Stwy A (6' 1") speaking lengths

[Alan Eder]

Gene,


I thought increasing back scale lengths might be the reason why, but have learned the hard way not to assume anything.  So, was the difference in lengths gained solely through the elimination of the cantilever, or was the base of the bridge also moved?  And I take it that there is a noticeable change, and you like it?


Thanks,


Alan Eder

Del Fandrich has taught about improvedtone with longer back scale length in the lo-bass and I believe him. Hisportable device demonstrates this for all to hear. If you get a chance to takethis class you should.
The lo-bass on this piano especially hadshort back scale and the extra 16mm helped get the back scale length closer to80 or 90mm on the lowest few notes – excluding the tied part of the wire- cannot recall exact lengths. I would have shortened the lo-bass speakinglengths more but was restricted by the plate casting.
The original bridge and its cantilever wasalso replaced with a new bridge and no cantilever.

Thanks for the info, Gene.  Lookslike you put the long bridge back in the same relative position to the plate,but shortened up the speaking lengths in the bass by 12 to 16 mm.  I wouldbe very interested in knowing what led you to make this change? 

 

Thanks again,

1909 A original

#1=1415mm

#20=1078

#21=1207

#88=51

Rescaled – new board, strings, bassbridge and bridge capps, block etc.

#1=1399

#20=1066

#21=1207

#88=51
