Hello Andrew, If the action is mounted on medal studs about one to two inches high then changes to the down weight is easy. You can bend the studs backward ( toward the soundboard ) about 1/16th of an inch. This can make an enormous difference. This changes the leverage of the whip. Another thing you can do is polish ( buff ) the back of the " bi-level " arm and lubricate the whippen heel felt. The piano action is simply a connected assembly of levers. There is no magic or mystery to it. I have worked on these pianos many times over the years, they are a little different but that's about all. Never adjust the actions studs in this manner on imported pianos. Regards, Jack Wyatt Dallas Chapter In a message dated 6/8/2010 1:11:36 P.M.

The patient is a Weaver spinet with pot metal(?) bi-level rocker arms. Schaff part 3782 pg 130. The down weight is north of 140 grams for much of the piano and up wieght is 20 - 30 ish. What if anything can be done? I love creative solutions and am not afraid of doing some significant surgery if necessary. But since leading the keys is not going to help here I am not sure where to go next. Thanks for anything you can do. -- Andrew Remillard ANRPiano.com 2211 Curtiss St. Downers Grove, IL 60515 630-852-5058 -------------- next part -------------- An HTML attachment was scrubbed...
