---------------------- multipart/alternative attachment Hey Carl Seriously though I wouldn't choose the Stwy style 2 as your first reve= rse crown soundboard project. I have done one of these and it came out st= upendous even though it was scaled and pitched at A- 458. Sitka board and= sugar pine ribs worked really well. Yes and your not seeing things. This piano ,f you install a new board = ,will require a bridge movement alteration and possible scale change so t= hat you can tune and play it in modern pitch. String length at note A -85= was like 1 and 3/4" or 1 and 13/16" for a tension of about 105 lbs. Whic= h is way to low. The whole scale showed the same anomaly and resultant im= provement once the tension reached A-440 tensions. It won't bark or meow = at that tension. At 458 it finally got up to about 135lbs (at note 85). = or so. I can't even begin to tell you how pleased I was with the power an= d clarity of that piano when I finally got up to pitch. =20 And you know the agraffes all the way to the top were not a detriment = but I believe now that they contributed to the sustain of the piano by no= t bleeding energy away from the speaking length like modern FRONT duplexe= s do. And hey Ron N. no rear duplexes and if memory serves adequately lon= g back scale. I really learned something as to why the stwy piano was so= oo popular even from the get go. This one was 1873. Dale Erwin =20 ----- Original : Re: Hamlet Davis bridge agraffes/ Reverse crown Steck =20 Gosh, Dale! That's interesting. =20 I've always thought that the more widely a belief is held the more apt is= to be false. Could that be true of crowned boards? If reverse crown sou= nds good, would you design and build me a reverse crowned board that I co= uld put in my style 2 S&S grand? I'm only partly kidding. Purposely putting in a reverse crowned board is= another one of the weird things I might try. =20 Regards =20 Carl Meyer Assoc.
