<DIV><FONT face="Arial Narrow"> Sounds like something a
factory would do. And it explains why, probably, I encountered a brand-new
Boston studio where the lost motion wouldn't stay put. I regulated
capstans, then proceeded to tune. After tuning, many notes again had way
too much play. Turns out, on a hard blow, the capstans would just get
pushed down into their holes. The dealer replaced the piano.</FONT></DIV>
<DIV><FONT face="Arial Narrow"> But I can "see" a factory
doing that, actually, to save time, if their experience shows that the capstans
stay tight in the wood. </FONT></DIV>

most capstan screws do have fairly fine machine threads, not wood screw
threads. But if I were replacing capstans, or moving the capstan line, or
installing wood inserts, I would drill the holes.</FONT></DIV>

Del once told me that is exactly what is done. I still haven’t tried it but I
guess it works. I saw it once at a factory and couldn’t believe what I was
seeing at the time. I think my mind just assumed that the bit contacting the
capstan top was spinning and the friction between them caused the capstan to
spin also, but not so. They were being pushed in. <o:p></o:p></SPAN></P>
