This is what this list is for.</FONT></DIV> <DIV><FONT face=Arial size=2>I will start off by saying that I am self taught, I listen to the pianist and I feel the note. Of course filing the hammer is going to reduce the weight etc but not by that much. If the hammers are filed evenly then the noticeable difference will be minute.</FONT></DIV> <DIV><FONT face=Arial size=2>Obviously in your regulation of the action you have neglected to adjust the repetition springs tension.  After the spring tensions have been adjusted then it will pay to go over all the other dimintions again as most regulation points will vary with every adjustment.</FONT></DIV> <DIV><FONT face=Arial size=2></FONT> </DIV> <DIV><FONT face=Arial size=2>These should be adjusted to rise with a good lift after the hammer is released from check. If they rise too fast the hammer will hit the string with a little 'ting' and if they don't rise then the repetition will suffer.</FONT></DIV> <DIV><FONT face=Arial size=2></FONT> </DIV> <DIV><FONT face=Arial size=2>The hammer filling should be to give the correct face on the hammer where it strikes the string (a rounded surface) with the centre of the wood in the middle of the strike point.  I prefer to round the shoulders as I am rounding the face of the hammer but it's a good idea to leave a lot of the shoulder on as it is weight. Just keep them even on both sides for good balance.</FONT></DIV> <DIV><FONT face=Arial size=2></FONT> </DIV> <DIV><FONT face=Arial size=2></FONT> </DIV> <DIV><FONT face=Arial size=2>Have fun</FONT></DIV> <DIV><FONT face=Arial size=2></FONT> </DIV> <DIV><FONT face=Arial size=2>Tony</FONT></DIV> <DIV> </DIV> <DIV> </DIV> <DIV> </DIV> <DIV>----- Original Message ----- </DIV> <BLOCKQUOTE style="PADDING-RIGHT: 0px; PADDING-LEFT: 5px; MARGIN-LEFT: 5px; BORDER-LEFT: #000000 2px solid; MARGIN-RIGHT: 0px"> <DIV style="BACKGROUND: #e4e4e4; FONT: 10pt arial; font-color: black"><B>From:</B> <A title=danilo.perusina@hotmail.com href="mailto:danilo.perusina@hotmail.com">Danilo Perusina</A> </DIV> <DIV style="FONT: 10pt arial"><B>To:</B> <A title=pianotech@ptg.org href="mailto:pianotech@ptg.org">pianotech@ptg.org</A> </DIV> <DIV style="FONT: 10pt arial"><B>Sent:</B> Tuesday, June 19, 2007 9:27 AM</DIV> <DIV style="FONT: 10pt arial"><B>Subject:</B> Keep on filing...</DIV> <DIV><BR></DIV> <DIV> <DIV class=RTE> <P><FONT color=#000000>Thanks David and Randy!</FONT></P> <P><FONT color=#000000>Sorry, I think I created the wrong impression. I'm not a do-it-yourself'er, I'm training to become a fully qualified technician. The hammers I've already filed, but not sure quite how much I dare take off from the shoulders? I've done a complete regulation of the action wtih 47mm blow, 1mm letoff, 1mm drop etc and the result is very good! However, the weight-ratio is off; down-weight is ca 40-42 grams and, as I said, the repetion-lever spring is too bouncy or too slack. Again, can I expect this behaviour from the spring when the hammers have been filed down so much? I hope I don't cause any offence in asking, but if I do, I'll stop posting.</FONT></P> <P><FONT color=#000000>Regards, Danilo </P></DIV></FONT></DIV><BR clear=all> <HR> Se dina favoriter live! <A href="http://g.msn.com/8HMBSVSE/2731??PS=47575" target=_top>Världsartisterna syns på MSN</A> <P> <HR> <P></P>No virus found in this incoming message.<BR>Checked by AVG Free Edition. <BR>Version: 7.5.472 / Virus Database: 269.9.0/853 - Release Date: 6/18/2007 3:02 PM<BR></BLOCKQUOTE></BODY></HTML>
