Thanks Ed for your Questions, One the Owner/Teacher loves the fast & light action . When I first assembled it and set it up I felt that it might be to light as far as touch . The other teacher says it's to light . She and some of her students have trouble with control of sound . When I first looked at the Hammers from Renner to me they looked smaller & felt lighter than the originals . The whippens came from Yamaha . So the only parts that might have made this action lighter would have been the hammers shanks & knuckles. I used the specs from my action hand book for regulation . I guess I need to read up on the key weighting and learn how to finish the job right . I just thought that maybe there was one of those rules that might apply to this like if light do this and if heavy do something else as far as regulation . But if it's the lighter hammer assembles than I guess the right way to correct it is by adding the weight back . No short cuts .? Thanks for any ideas , Brett It is not clear from your post what the complaint is. Is the "local teacher" satisfied that the action is fast and light? Is the other teacher complaining it is too heavy? What kind of "hard time" are the students having? Hard time pressing the keys or hard time controlling the sound? What is your impression of the piano? Have you voiced the hammers? Have you taken basic down and up weight measurements?
