Steinway O revisited

[David Love]

I've done them both ways (fanned and original rib positions without
significant compression) and haven't found a huge difference.  Fanning the
ribs seems to reduce resonances some (though it doesn't seem to eliminate
them entirely), it also allows you to float the bass (which I didn't do on
this project).  The panel was ribbed at 6% (30%RH @ 85 degrees F) so it does
have just a bit of compression.   On some projects, you have to make
choices.

    Since the original rib scale was originally designed to work in
conjunction with panel compression stiffness are you concerned  about any
potential unwanted soundboard resonance's by retaining the original rib
scale placement & same no. of ribs even though they are beefed up to support
the entire crown load?

Here's a Steinway O with modifications: transition bridge (old style
connection), cut-off, modified bass bridge sans cantilever, adjustable plate
mounting system.  Vertical hitches in the plate in the treble section (not
pictured).  Plate goes in today.
