Terry, Would you make any adjustments or compensations in the measure speaking lengths for the flexing of the plate or the movement of the bridges when the piano is strung?? Robin ----- Original Message ----- From: Farrell To: Pianotech List Sent: Tuesday, August 01, 2006 11:10 AM Subject: Re: Help scaling FWIW, some years back I had the same situation with a piano. I measured all the speaking lengths and sent them to David Sanderson. He scaled the entire piano very nicely for me. Terry Farrell ----- Original Message ----- I have the task of restringing this Schaff baby grand (see small pic). Unfortunately all scaling information was discarded, along with the old strings and tuning pins, before I showed up. No idea what sizes any of the strings were, nor what gauge the tuning pins were. Also, the plate has been removed (though fortunately not discarded!). I have never done a scaling analysis but am possessed of a very analytical mind, so I am eager to do as much of this as I can myself. But please: what are the steps? Here are my assumptions. I will need to replace the plate so that I can take measurements of the speaking lengths, probably to nearest mm or 32nd. (.01"?) I'll need an app like ScaleMaster or Pscale to crunch some numbers. I will need to examine the pin block to determine tuning pin size. (Can I measure a hole nondestructively, i.e. without pounding a pin into it?) I'll need some kind and experienced mentor-type soul to review my analysis before I go to the step of ordering bass strings. Any help out there?
