Floyd,
I just restrung a 1941 Steinway "40". I had Gregor Heller redesign the bass strings using Paulello where optimal, I did not change any of the scaling parameters other than changing to Type 0 wire from the bass break up to halfway through #17 gauge, then the rest is IG.
So far there is a significant improvement in the piano. Still a tad weak right at the top of the bass, but better than it was previously. I will add riblets soon to calm the transition down. I expect it to come out surprisingly well.
Oh yes I almost forgot...the pressure bars were VERY rough on the business side. I spent some time on the deburring wheel polishing them out. The roughness was East/West which would easily explain rendering issues in these pianos. TBH, I was pretty shocked to find it this bad. Of course my polishing job went North/South to reduce any tendency toward resistance. Rendering is quite good now, but of course all is now new. I also dressed the cast counter bearing bar on the plate. That one wasn't bad and cleaned up pretty quickly.
