It simply will not stay in tune. My colleague at Glyndebourne had tuned it the previous day - and, like.... it was horrible! Not just the 8ves, but the unisons also. He invited me to "have a go" - which challenge I took up with gusto! Next day I had a "look" at the tuning and found that... although it wasn't as bad as when I started the previous day it had indeed drifted. Now <EM>I</EM> think the web bushings are soft and the wrest pins are flag-poling. So I have a notion to inject some CA in there to try and solidify those bushes. What does the Team think?</FONT></DIV> <DIV><FONT face=Arial size=2>Regards from a Bartered Bride day in the Sussex Downs</FONT></DIV> <DIV><FONT face=Arial size=2>Michael G.(UK)</FONT></DIV></FONT></BLOCKQUOTE></BODY></HTML>
