I used Franklin cold hide = glue. Knowing that it was not going to be part of a real piano, I chose to use a = bottle of glue that I knew had been sitting around longer than I was comfortable = with (long ago I chose not to use it on a real piano). While applying the = glue to the fake rim, the glue started out nice and transparent like hide glue = should be. The last bit though came out cloudy. When I clamped some of the glue ran = out from the joint and onto my work table. After cleaning up the rim, I went = to clean the table - the clear glue had dried and was hard but the glue = that came out cloudy was still sticky.</FONT></DIV> <DIV><FONT face=Arial size=2></FONT> </DIV> <DIV><FONT face=Arial size=2>So from this one experience I observed = that old hide glue that is clear may still be good, while cloudy hide glue may = not yield a good bond. I don't know if that is a definitive relationship, but I do = know that if I ever see cloudy hide glue, I won't use it.</FONT></DIV> <DIV><FONT face=Arial size=2></FONT> </DIV> <DIV><FONT face=Arial size=2>From the TiteBond web site for cold = hide glue: Storage life <IMG src="http://www.titebond.com/images/clear.gif" = width=3>12 months in tightly closed containers at 75°F.</FONT></DIV> <DIV><FONT face=Arial size=2></FONT> </DIV> <DIV><FONT face=Arial size=2>Terry Farrell</FONT></DIV> <DIV><FONT face=Arial size=2></FONT> </DIV> <DIV><FONT face=Arial size=2>----- Original Message ----- </FONT> <DIV><FONT face=Arial size=2>From: "Dave Nereson" <</FONT><A href="mailto:davner@kaosol.net"><FONT face=Arial size=2>davner@kaosol.net</FONT></A><FONT face=Arial = size=2>></FONT></DIV> <DIV><FONT face=Arial size=2>To: <</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: Tuesday, July 06, 2004 8:15 = AM</FONT></DIV> <DIV><FONT face=Arial size=2>Subject: cold hide glue shelf life</FONT></DIV></DIV> <DIV><FONT face=Arial><BR><FONT size=2></FONT></FONT></DIV><FONT = face=Arial size=2>>     Tried to glue hammer shanks with cold = hide glue (Franklin) last night<BR>> and the stuff just would not set up.  = Three hours later and I could still<BR>> pull the shank out of the butt as = tho' it had no glue at all!  It's a bottle<BR>> I've had for a while, = but probably not more than a year or so.  Worked fine<BR>> a couple = weeks ago.  It gets warm and cool in the shop, but not really hot<BR>> = or cold.  Does the stuff have a short shelf life?  The cap's been = on the<BR>> whole time.  Other bottles I've had never did = this.  -- David Nereson, RPT<BR>> <BR>> <BR>> _______________________________________________<BR>> pianotech list = info: </FONT><A href="https://www.moypiano.com/resources/#archives"><FONT = face=Arial size=2>https://www.moypiano.com/resources/#archives</FONT></A><BR><FON= T face=Arial size=2>> </FONT></BODY></HTML>
