  • 1.  Replacing Yamaha hammer butt flanges

    Posted 3 hours ago

    This goes in the category..lesson learned..and also "have a slice of humble pie".

    So a customer asked me to repair her 45 year old Yamaha console action..all the hammer return springs were "popped up".  I have done several of these over the years and used Tokiwa parts each time.  Then recently, I saw these flanges on Ebay at 33 cents each and thought that it would be cheaper but essentially the same flange as the Tokiwa.  Well, cut to installing the action and the customer played it and said "the action feels restrained".  So I took it back home and compared the flange to an old intact flange and sure enough, the Ebay flange butt cord string was about 1/16th inch and slightly longer than the original.  So I believe that is what is slowing down the hammer return and making it feel restrained.  So now I get to do it using the correct Tokiwa flange.

    I don't think the length of the butt cord, or spring loop as we also call it, had anything to do with having the action feel "restrained". I think what she was feeling was the hammers coming back faster than before, when the spring loops were broken. In other words, she had gotten so used to the action not playing correctly, that when it did play right, it felt different, and she didn't like it. Kind if like when the piano is finally tuned right, and to some customers it doesn't sound the way they had gotten used to it.

    This is what I initially thought as well, but I figured if I reworked it and took it back that might "fix it".

    Patrick,

    Did you carefully check if the replacement flanges had dimensional specifications exactly as the original Yamaha? The slightest difference could make for a noticeable touch change. The last time (3 years ago) I purchased Yamaha flanges they were just over a $100 for the set. I'm sure they're more now, but I had no fear the new flanges would seize up due to poor bushing cloth, and I experienced little to no lateral alignment or traveling issues, saving me installation time.
