Of course that's only ro remove a few inches. To do the entire length, she should keep cutting off the loose wire to keep it from spinning. This won't work very well on the thinner strings, about size 10 or higher. On the very thick wire it will be difficult to get an end started</DIV> <DIV> </DIV> <DIV>Wim <BR></DIV> <DIV>PS. I've often wondered if this was worth doing to work. With the price of copper as high as it is now, it might not be worth it for us, but it might worth it for a pre-teen. <BR></DIV> <DIV style="CLEAR: both"></DIV><BR><BR> <DIV style="FONT-SIZE: 10pt; COLOR: black; FONT-FAMILY: arial,helvetica">-----Original Message-----<BR>From: Rob McCall <rob@mccallpiano.com><BR>To: pianotech <pianotech@ptg.org><BR>Sent: Thu, Jun 30, 2011 8:35 pm<BR>Subject: [pianotech] Copper recycling of bass strings<BR><BR> <DIV id=AOLMsgPart_0_57c5fcd0-7892-4a24-b02e-a082a9cd77cf style="FONT-SIZE: 12px; MARGIN: 0px; COLOR: #000; FONT-FAMILY: Tahoma, Verdana, Arial, Sans-Serif; BACKGROUND-COLOR: #fff"><PRE style="FONT-SIZE: 9pt"><TT>Hi all, I have a set of bass strings I removed from an old grand. My 13 year old wants to know if she can have the money from recycling the copper. The recycling place won't take it if it's still wrapped on the steel core. I've tried to find an easy way to have my daughter remove the copper but the effortless method has eluded me to date. :-) Anyone have any ideas?
