Ron: Looking at it again I could actually move it up fairly easily without any plate grinding since there is a bit of room from where A0 crosses and the end of the bridge. My scale experiments suggest that this scale looks a bit better with 12 or 13 monochords in the bass instead of 10. I'd be curious to know how many notes on your transition and what the speaking lengths at the beginning and end were.

I think I'd do that. I got 135mm A-0 in a model L I'm finishing up. Ron N
