<DIV>List, sometimes letting the problem continue isn't just a repetition problem. Many times the butt springs can be damaged when they get in the way of the hammer shank travel. Then you have a small job turn into a very large job.</DIV>

Well....today, tuned<BR>for a long time client with a Yamaha Console, built in 1970. Tuned almost<BR>the entire piano and your butt spring cord posts flashed before my eyes,<BR>which prompted me to check. Aha! this piano had 46 broken cords! The really<BR>weird thing is that it is not apparent to either me or my client, who plays<BR>very well, (as does his daughter). The repetition does not seem to be<BR>affected in any way!<BR>On closer examination I observered that the action "set up" is such that it<BR>is "tipped" to compensate for the lack of any real "assist" that stupid<BR>spring might give! At hammer contact, the hammer is just barely past<BR>vertical center. I surmise that the hammer resilience/rebound brings it back<BR>past center, allowing
gravity to do the work. Just my thoughts on this. On<BR>my suggestion, the client will not have me do the cord replacement, unless<BR>it becomes a problem.<BR>Just some thoughts on this.<BR>BTW, this is one item that is not in my "Repair Labor Guide". I would be<BR>interested to have anyone, that has done this job, email me privately,<BR>regarding the time necessary to accomplish this repair. I, only ask, that<BR>you be honest. Please don't let your ego get in the way of what the "actual<BR>times" are/were. I'll compile the info and add it to the next edition.<BR>(averages are what it's all about. So's it's fair.)<BR>Best Regards,<BR>Joe Garrett, RPT, (Oregon)<BR>Captain, Tool Police<BR>Squares Are I<BR><BR>_______________________________________________<BR>pianotech list info: https://www.moypiano.com/resources/#archives</BLOCKQUOTE>
