After all, the CA treatment is specifically to lengthen the tuneable = life of the piano, before major work will be needed or the piano is scrapped. Having = said this, we all need to be very specific with clients regarding this = procedure. We must tell them this is a last ditch effort and anything beyond that will = be Rebuilding and replacing the block. IMO, CA does work much better than = the olde "pin dope". As for longivety, who can tell, at this point. I think we = all are hoping it's like the non-biodegradable plastic in a land fill.....it = just won't go away. I do think that the CA will have a "life expectancy", but what = that is, is very hard to tell, at this time. I probably won't live long enough to = find out, in regard to the ones I've done.</DIV> <DIV>On a similar subject, I have had my first failure with CA. We = attempted to resurect an olde beater/tuning practice piano, and it didn't work! So = now, the student gets the experience of putting over-sized pins in it.<G></DIV> <DIV>Best Regards,</FONT></FONT></DIV> <DIV><FONT face=Arial size=2>Joe Garrett, R.P.T.<BR>Captain, Tool Police<BR>Squares R I</FONT></DIV></BODY></HTML>
