There is much to be learned = here. Be honest now, all of you - what percentage of your home clients (as = opposed to schools and Opera houses) have grand pianos? The wish is there, but the = grand is not. No, it is the humble upright which fits the bill for most = aspiring pianists at home. So let's keep this thread on the go. Or is it really = that the majority of private homes in all places but the UK are so very much = larger and have the room for a grand? In the UK the upright is the true = bread-winner for the PTs. I have about five schools to tune for and in one of these there = are some 25 pianos. Of these only four are grands - 2 S&S "A", 1 Yamaha = CF and a non-descrip baby grand. All the rest are uprights. Yamaha U3, Bluthner, = Welmar, Knight, Steck, Rogers, Challen, Chappell, Broadwood ... .  the = list seems endless. Each piano make has its idiosyncrasies and they are = all pianos you have probably never heard of out there in the West. They all = have one thing in common though - they can be played, practised upon and even = cherished. And they certainly need tuning. And tuning means MONEY. So we mustn't = knock the "humble" upright. We must take it seriously and give it, its maintenance = and foibles, air-time on the List.</FONT></DIV> <DIV><FONT face=Arial size=2>Question. Given that in a Steinway = upright Model "V" it is stipulated that the damper springs are weighted at the factory = bass 35gr. treble 37 gr. WHERE is the weight applied to conform to this = requirement? Is it on the body of the damper (just behind the groove the spring sits = in) or on the damper head? Obviously the further you get away from the fulcrum = the greater is the effect of a given weight. But an accurate = answer is the only answer here. Over to you guys.</FONT></DIV> <DIV><FONT face=Arial size=2>Regards from a Downland Village in Sussex</FONT></DIV> <DIV><FONT face=Arial size=2>Michael G.(UK)</FONT></DIV> <BLOCKQUOTE dir=ltr style="PADDING-RIGHT: 0px; PADDING-LEFT: 5px; MARGIN-LEFT: 5px; = BORDER-LEFT: #000000 2px solid; MARGIN-RIGHT: 0px"> <DIV style="FONT: 10pt arial">----- Original Message ----- </DIV> <DIV style="BACKGROUND: #e4e4e4; FONT: 10pt arial; font-color: = black"><B>From:</B> <A title=kpiano@goldrush.com = href="mailto:kpiano@goldrush.com">Keith Roberts</A> </DIV> <DIV style="FONT: 10pt arial"><B>To:</B> <A = title=pianotech@ptg.org href="mailto:pianotech@ptg.org">Pianotech</A> </DIV> <DIV style="FONT: 10pt arial"><B>Sent:</B> Friday, February 25, 2005 = 6:07 PM</DIV> <DIV style="FONT: 10pt arial"><B>Subject:</B> Re: upright balance = weight</DIV> <DIV><BR></DIV> <DIV><FONT face=Georgia size=2>Terry, No I didn't.

I'm surprised at the amount of friction. = </FONT></DIV> <DIV><FONT face=Georgia size=2></FONT> </DIV> <DIV><FONT face=Georgia size=2>I don't think we should use Grand = weighting as the criteria for what makes an upright the most enjoyable to play. The = grand DW is affected by the friction at the knuckle which is determined by = the hammer weight and the friction of the shank centerpin. The more the f</FONT><FONT face=Georgia size=2>riction and weight in the bass = compounds the friction at the knuckle and forces a graduated touchweight. This = doesn't necessarily mean it's better. The upright hammer doesn't have the = force of gravity to overcome in the same way as a grand and so makes an evenly = weighted keyboard possible. A heavy DW means the fingers get tired quick. The = left hand in particular. A light flinging action would be more conducive to bass = trills, tremolos, and rifts such as Clementi, maybe even that Steinway artist = with the filed down hammers, Horowitz? The heavy hammers on grands now make it = so you have to work out at the gym to play Christmas carols. OK, I've tried = to stir up some, uh, controversy. Hopefully the semantic police won't bury me.</FONT></DIV> <DIV><FONT face=Georgia size=2></FONT> </DIV> <DIV><FONT face=Georgia size=2>Basically with this action, I want = to lighten up the touch weight with the geometry first.  That's why I want a = target weight so I can maximize the capstan move if it looks as if  the = goal weight will still have to be adjusted with lead. 40 to 41 gram BW = is what I'm liking right now. </FONT></DIV> <DIV><FONT face=Georgia size=2>kpiano</FONT></DIV> <DIV> </DIV> <DIV><FONT face=Arial size=2><FONT size=3>I think you = misinterpreted my comment.
