Scaling

Wrong. Measured all strings and all stamped sizes corresponded with the American sizes. There isn't any signs of being rebuilt before, so I'm beginning to rule out that it wasn't a previous technician's error who strung with the wrong sizes.

       Wrong assumptions on both counts.  Japanese wire sizes are 1/2 size larger than ours  thus making your first wire size 13 1/2.  Measure it with a micrometer & you'll see.  Been there done that.

      Tom asked: "Just unstrung an older Kawai model 500 grand. I was astonished to see that 
      their first wire size was a #14. Thinking about rescaling this down in 
      tension a bit. Anyone out there have any experience with rescaling this 
      mode?. This looks like the pre-cursor to the KG2 model."

      Tom,
      I wouldn't! The soundboards on that model are quite thick and a #14 wire is appropriate. (Ya have to look at the Whole picture.<G>) It behooves you to get a Scaling Program and play around with this sort of stuff.<G> Then practice/experiment on your own stuff. (which entails a lot of "oops! Better Change That!"<G>)
