<DIV><FONT face="Times New Roman" color=#000040 size=4> In the sp=
irit of "make a soundboard" I continue to observe things that work (or not)&=
nbsp;I currently have a 1960 L in shop for finish stringing & some actio=
n sprucing. The piano has always lived in a Church sanctuary in Fresno, Ca. =
These people love this piano & were concerned about changing the sound s=
o....</FONT></DIV>
<DIV><FONT face="Times New Roman" color=#000040 size=4> When a p=
iano sounds really, really good I'm always asking, I wonder why. The pi=
ano had nicely set bearing & with the strings on as evidenced =
again with the strings off. </FONT></DIV>
<DIV><FONT face="Times New Roman" color=#000040 size=4> The amaz=
ing thing for me is this sound board has more crown thru out its entire rib =
scale than most S&S I've encountered. I don't work on many this you=
ng. I stretched a string across the bottom and starting between the top two =
ribs. It had 2 mm of nice hemispherical crown. That equates to approx. 30ft =
radius. Continuing on down & measuring between each rib it had 3.4 =
, 4 , 5 , 6 , 6, 5, 4, 3 mm of crown. after doing a mock up pre-stressing ch=
eck of the bearing it had roughly 2 degrees of bearing in the top 2 sections=
tapering down to 1&1/2 degrees in the tenor starting in at the treble t=
enor break The bass was set almost to zero. It was really fairly text b=
ook S&S bearing set up.</FONT></DIV>
<DIV><FONT face="Times New Roman" color=#000040 size=4> Also the=
re is only the faintest sign of any compression ridging & that only on 1=
joint. Modest annular ring spacing (10-12 grains an inch).</FONT></DIV>
<DIV><FONT face="Times New Roman" color=#000040 size=4> I've rar=
ely measured any crown in the top end of S&S's let alone such tight radi=
i for a CC crowned board. I was wondering if it was rib crowned but I don't =
think so. Looks to be about . 330 thick in the middle. It has significant cr=
own along the bridge as well, but of course the crown hasn't sunk.</FONT></D=

<DIV><FONT face="Times New Roman" color=#000040 size=4> It's tru=
e that it's survived well because of our moderate Ca. climate but also somet=
hing was right when the board was made. This the easiest rebulding I do &=
; this kind of thing makes it fun & interesting.</FONT></DIV>
