#635094 - 07/02/02 08:23 PM Whippen tension question...

Hello again folks,

I would like to know if the spring tension of each whippen assembly is supposed to vary between the low notes and the high notes. I ask because I need to replace 7 missing Whippen assemblies in my Yamaha CP70 electric grand. And I seem to notice that the back tension excerted by whippen on the lower notes seems to be greater than that of the higher notes.
Am I just being hypersensitive here or is this really the case?

Thanks again,

David Krappon

David,

Spring tensions of the whippen should be uniform throughout the range as all the hammers are of identical dimensions in the CP series unlike acoustic pianos.

Are you measureing the "tension" of the whipen as how quickly the hammer rises arter putting the hammer in check. or are you just feeling the overall weight difference between the heavy and light hammers?????

No I'm doing it just by feeling the tension exerted by the whippen when I push on it.
