Many of these piano get fairly rough use 7 days per = week (piano bar and all that). So we're searching for a better way.

I don't see that the supply houses offer plated/steel = pins in the Yamaha size.</FONT></DIV> <DIV><FONT face=Verdana></FONT> </DIV> <DIV><FONT face=Verdana>So maybe we need to use cloth key bushings. I = heard from some that Renner has the most durable key bushing cloth. Any opinions on = that?</FONT></DIV> <DIV><FONT face=Verdana></FONT> </DIV> <DIV><FONT face=Verdana>What about lubrication on the cloth bushing material to minimize friction and increase longevity? Microfine = Teflon powder? But doesn't that just sort of fall out quickly? What about some = sort of graphite? A synthetic grease, maybe like VJ lube? Anyone ever try = anything like that? Any other ideas (constructive)?</FONT></DIV> <DIV><FONT face=Verdana></FONT> </DIV> <DIV><FONT face=Verdana>Maybe I should just stand in back of the piano = player with a whip or a well proportioned maple 2 x 4?</FONT></DIV> <DIV><FONT face=Verdana></FONT> </DIV> <DIV><FONT face=Verdana>Thanks.</FONT></DIV> <DIV><FONT face=Verdana></FONT> </DIV> <DIV><FONT face=Arial size=2><FONT face=Verdana size=3>Terry Farrell</FONT></DIV> <DIV><BR></DIV></FONT></BODY></HTML>
