I will also do it = that way sometimes on a wooden flange before I push the pin through the flange = (usually at the beginning of the process when I am calibrating reaming, etc.). = FWIW though, one thing I have noticed is that to get the four or five swings = (or whatever your target is) with the flange in place, you will typically = need to see only two or three swings without the flange but just holding the = pin. Hard to imagine exactly why this discrepancy exists. Perhaps there is a = bit of friction between the side of the wooden flange and the side of the = butt/shank. So somehow, you might want to incorporate a potential friction = discrepancy between the two methods - who knows, maybe it is only on a wooden flange = and it won't occur on a brass rail.</FONT></DIV> <DIV><FONT face=Arial></FONT> </DIV> <DIV><FONT face=Arial>Another way around this is to convert the brass = rail to wooden flanges.  ;-)</FONT></DIV> <DIV><FONT face=Arial></FONT> </DIV> <DIV><FONT face=Arial>Terry Farrell</FONT></DIV> <DIV><FONT face=Arial></FONT> </DIV> <DIV><FONT face=Arial size=2>----- Original Message ----- </FONT> <DIV><FONT face=Arial size=2>From: "Michael Spalding" <</FONT><A href="mailto:spalding48@earthlink.net"><FONT face=Arial size=2>spalding48@earthlink.net</FONT></A><FONT face=Arial size=2>></FONT></DIV> <DIV><FONT face=Arial size=2>To: "</FONT><A href="mailto:joey@onkeypianotuning.com"><FONT face=Arial size=2>joey@onkeypianotuning.com</FONT></A><FONT face=Arial = size=2>, Pianotech" <</FONT><A href="mailto:pianotech@ptg.org"><FONT face=Arial size=2>pianotech@ptg.org</FONT></A><FONT face=Arial = size=2>></FONT></DIV> <DIV><FONT face=Arial size=2>Sent: Monday, October 13, 2003 7:45 = PM</FONT></DIV> <DIV><FONT face=Arial size=2>Subject: RE: Brass Rail = Tension</FONT></DIV></DIV> <DIV><FONT face=Arial><BR><FONT size=2></FONT></FONT></DIV><FONT = face=Arial size=2>> Joey,<BR>> <BR>> While fitting the pin, (i.e. before = the pin has been clipped to length) you<BR>> can slip the pin into one or = both sides of the bushed butt and, holding the<BR>> protruding end of the pin, = swing the hammer.  One bushing at a time lets<BR>> you equalise the fit = between the two sides.  No way I know of to put a gram<BR>> scale on it, = but you quickly get a feel for the right amount of friction.<BR>> <BR>> Mike<BR>> <BR>> <BR>> > [Original Message]<BR>> > = From: Joey Recker <</FONT><A href="mailto:joey@onkeypianotuning.com"><FONT = face=Arial size=2>joey@onkeypianotuning.com</FONT></A><FONT face=Arial = size=2>><BR>> > To: Pianotech <</FONT><A href="mailto:pianotech@ptg.org"><FONT = face=Arial size=2>pianotech@ptg.org</FONT></A><FONT face=Arial size=2>><BR>> > Date: 10/13/2003 6:15:57 PM<BR>> > = Subject: Brass Rail Tension<BR>> ><BR>> > How do I check the tension for = center pins in a brass rail?<BR>> ><BR>> > I'm working on a 1907 M. = Schulz upright.  It has a brass rail.  Most of<BR>> > the = hammers are sluggish.  No sign of vertigris etc...  <BR>> ><BR>> = > I've started re-pinning the hammer butts (had to rebush a few that = have<BR>> > come apart during the process).
