Greg: The float is usually done in the bass to give the tail of the soundboard more flexibility and enhance the bass response. In order to do that the rib array is usually fanned so that the #1 rib is pretty much parallel to the belly rail. At least that's what I've seen. There are others who are better equipped to speak to the theory of rib alignment as it relates to bass floats. The ideas that appear on this particular O are not mine exclusively but have been discussed in great length on the list (and in articles and conventions) by several people. With a bit of research through the list there is an abundance of information for the taking plus there are a number of regular contributors who are and have been very generous with sharing their thoughts and methods. The O makes a great rebuilding piano and offers many opportunities for changes and improvements (yes, I did say that didn't I?) should you decide to go that route.

I made a trade for an "O" and while it will be quite some time before I am ready to do anything with it I am certainly interested in your ideas. The "O" will have to sit unless someone is willing to offer me an obscene amount of money for my Bosendorfer. :-) Greg Newell Greg's Piano Forté www.gregspianoforte.com 216-226-3791 (office) 216-470-8634 (mobile) -----Original Message----- From: pianotech-bounces at ptg.org [mailto:pianotech-bounces at ptg.org] On Behalf Of David Love Sent: Saturday, May 17, 2008 11:16 AM To: 'Pianotech List' Subject: Steinway O revisited Here's a Steinway O with modifications: transition bridge (old style connection), cut-off, modified bass bridge sans cantilever, adjustable plate mounting system.
