<html> Wim, <x-tab>        </x-tab>I was taught something early on that may help you. When regulating an action it's best to make a few passes at it. Similar I think to the multipass tuning everyone talks about. If you had gone through the action more than once I'm sure that you would have found that the spring tension was low. A common error is to set the spring tension before making at least gross adjustments to the checking height. If the checking height is near to normal the spring tension you set will stay nicely. If you don't  ... it won't. I hope this helps!

This winter I regulated all of the main pianos in the school, including the piano faculty pianos, with the rep spring set to give me that "gentle rise." Now, all of a sudden, piano players are complaining about poor repetition, and when I check out the pianos, there is almost no rise at all. Once upon a time I heard that the springs will change with the change in weather. But what is happening? How come all of my rep springs are flat? Inquiring minds want to know.
