It = says it is accurate to within 1/3 a graduation. It appears that graduations MAY = be each 5 grams. That means at best it is accurate to within 2 grams. But I = think you would be hard pressed to use it and compare your results with anyone = using a regular gram weight set. Especially when you consider the art of  = setting the appropriate amount of weight on the key end and giving a little bump = to overcome friction and then watching to see a uniform hammer rise. How = would you watch a hammer rise with this gizmo? It appears that it is only for = static resistance, it cannot measure the resistance of a key in motion. Spend = the bucks and get a good gram weight set.</FONT></DIV> <DIV> </DIV> <DIV><FONT size=2>Pianotek has a real nice one for $125 on Page B-5. = The one on B-25 is for static resistance. No good for key down and up weight. I = have Bill Spurlock's which are also real nice. Pianotek's may be a bit nicer in = that they lock together when you need to have two weights on the key, but I like = my set just fine, thank you. I may have paid a bit more for mine than Pianotek's.</FONT></DIV> <DIV> </DIV> <DIV><FONT size=2>The other way to do it is to get the real cheap set = from Schaff and use an accurate scale to modify the weights so that they are = actually accurate. Much easier to just call Pianotek and order. Be aware though, = the instruments you have cited in your post are for static measurements of resistance, not for anything that includes a dynamic form - like = weighting off a set of piano keys!</FONT></DIV> <DIV> </DIV> <DIV>Terry Farrell<BR>Piano Tuning & Service<BR>Tampa, Florida<BR><A = href="mailto:mfarrel2@tampabay.rr.com">mfarrel2@tampabay.rr.com</A></DI= V> <BLOCKQUOTE style="BORDER-LEFT: #000000 2px solid; MARGIN-LEFT: 5px; MARGIN-RIGHT: = 0px; PADDING-LEFT: 5px; PADDING-RIGHT: 0px"> <DIV style="FONT: 10pt arial">----- Original Message ----- </DIV> <DIV style="BACKGROUND: #e4e4e4; FONT: 10pt arial; font-color: = black"><B>From:</B> <A href="mailto:gleng@fast.net" title=gleng@fast.net>Glenn = Grafton</A> </DIV> <DIV style="FONT: 10pt arial"><B>To:</B> <A = href="mailto:pianotech@ptg.org" title=pianotech@ptg.org>pianotech@ptg.org</A> </DIV> <DIV style="FONT: 10pt arial"><B>Sent:</B> Saturday, October 14, = 2000 3:52 PM</DIV> <DIV style="FONT: 10pt arial"><B>Subject:</B> Gram Gauge</DIV> <DIV><BR></DIV>I'm looking for a gauge that would show the number of = grams it takes to depress a key.
