Sonora is a very dry climate & after 20 years=  in that climate the pins would jump & pop all over the block.= I mean like low torque, push, then pop slip. Setting the pins was well= .. impossible. I restrung it with a bolduc block &fully fit the new= block to the flange. Restrung with no plate bushings. It's fine. I guess th= e original beech block had suffered some kind of physical changes & who = knows why. With Yamaha this is fairly rare.</FONT></FONT></DIV> <DIV><FONT face="Times New Roman" color=#000040 size=4>   Da= le</FONT></DIV></BODY></HTML>
