Tho I would think the the control over touchweight and repetition part might be a bit overstated. Admitedly tho... I havent seen or serviced a piano with the spring rail in over 20 years, and I hold quite open the possiblitiy that Ken could show me a few neat tricks in that regard. Regulating the Schwander type is not something I even bother to try in the piano. If I do find they need attention, its a bench job... with all the guess work that entails. If someone has a trick and tool for doing this in the piano I'd like to hear it too. I also know about the bobble Ken mentions its possible to induce... and I find you can get this to happen throughout the bass as well. However.... you dont really play the piano with that touch. Someone mentioned the hammer butts with the built in jack stop cushion. I do prefer these over the jack stop rail myself. They stay put as it were. RicB -- Richard Brekne RPT, N.P.T.F.
