How on earth could DA be more hip? P In a message dated 2/9/2010 11:06:31 P.M. Central Standard Time, erwinspiano at aol.com writes: Hi David A couple pictures showing the rib array and scallop. I'm going to look at the rib scale again. I was trying to remember if I asked David L. to run a spread sheet on the rib scale. Neither had laminated ribs as I recall. It is intriguing to see how near the center of the ribs the bridge lies. By the way, he wouldn't tell you, but Dave Andersen just got a new hip. Go Dave!

The rebuilt "C" we brought to Rochester in 2006 has a RC&S board, and the tone in notes 68-76 got WAY better when we arced the line in, as Dale's pic showed. Whattup with THAT, Nossaman?

If it is indeed a difference between soundboard panel construction, the evidence albeit being sketchy at best so far, it is an interesting distinction and well worth studying. And my point, again, was that factory production rarely allows for deviations from straight lines, particularly in hammer production and installation. Nor was I imputing a presumption on your part.

I don't think it's primarily the soundboard. Meaning that in all the RC&S soundboards you've installed, you've never not had to deviate from a straight strike line? I'm not talking about assuming anything at all. "Whatever the soundboard structure" is the point, not factory presumption.
