---------------------- multipart/alternative attachment Hi Dave Well I tend to be an experiential type human & I know only that when I hear something I like I expore it. What I find interesting about what you've written below is that I see you (over the last couple of years) moving incrementally toward, for all practical purposes and based on what I've read on the list, a rib crowned and supported board. While you are still drying the panel down to 5.5% rather than the 6.5% that some of the RC&S people are doing, the taller, rather than wider, more ribs, fanned perpendicular to the bridge, cut-off bars, treble fish, is what I see in the RC&S designs. > Well since I can't get close enough to any body elses redesigns to hear them I have incrementally decided to expereiment in that direction. So I need to do my own & make up my own mind. I'm a bit nervous about the outcome as it's a huge financial risk & my yes , it is my piano. I have been thinkng about the Killer octave problems & I surmise by conjecture & intimation from other that what the remedy is is more support. so The Long A design is my solution , hopefully. I may be dismally disappointed. Having heard your boards and having heard others report on what they hear, it would seem, at least on the surface, that rib versus compression crowning is not a significant element in convincing people about the authenticity of what they are hearing. > Do you mean the sound speaks for it self regardless of the means to get there? Then I'd agree. Rather, it would appear, it is some other confluence of factors: panel thickness, shaping, grain angle, overall rib design and level of support, control of moisture content; etc., the usual stuff. Since those who have heard your pianos were not struck by anything unusual in their tonal output, You mean other than they really like them? would you then go so far as to say that RC&S, CC, RC&CC probably doesn't much matter? No I wouldn't. I.E.I've already stated my tonal preference for my Boards with white spruce ribs Subjective though it may be I've heard enough of them to know & all compreesion boards are made with sugar pine of which I've used in the past as well. Also with good results but the white gives the sound more clarity. JMHO. I my find that all the usual stuff ,as you say, that I do in my usual protocol may indeed prove to be a better formula for me since it's producing a good outcome & is a known quaantity. I'm always one to but the better mouse trap , so I'll see, & I will report back with candor & honesty.... After the piano is sold...grin At least in the short term? How each might hold up in the long term and the consistency with which each can be produced, and, moreover, the choices one makes about their own design elements might yet be another matter. But from what is written below, it sounds as if tonally, you are leaning toward what many of the RC&S designers are advocating. Do I read that correctly? Well all I know is that in many of the older designs I hear the most sustain & musical life in are from these old boards. You explain it to me please. Yes, They were probably compression crowned. I don't know if the ribs were crowned except perhaps a little on the Ludwig. I haven't even checked the crown. But I will & report after I take the strings off. Fair enough. I do think that in any case the number of taller ribs gives more stiffness to the crown support. & even when a board like those mentioned has only little crown left they stil have amazing tonal properties. I'm just trying to observe these design when they strike me as excellent sounding & then try to find a reason. Simply with more ribs in the system adds more weight& stiffness & thus more mechanical impedance. In the Ludwig I don't find any weak notes. This piano is 100 years old. Original strings. So all the concerns with longevity considering even slight design improvements is almost a mute & funny point to me. I know my boards won't cave in even in 75 yrs so for me Its about the sound... Yes! If these other designs give me even more of what I want then.................
