    Need some help to regulate the action of an 1877 C Bechstein that was rebuilt . rep springs need more tension but I also need to know how I adjust the hammer blow distance since there are wooden rockers on the keys with 2 screws. Damper lift from the keys is early giving a heavy touch and then jack is noisy when it returns to rest and hits a piece of bushing cloth that is in front of a felt strip. There is no round felt button or spoon so I think needling the felt will reduce the noise.

    James: I worked on a Bechstein recently, also rebuilt, where rebuilder used felt on the under levers that was a bit too thick, so early lift. The felt on the damper tray was also a bit thick, so I decided to live with that. Damper heads are pretty light, so didn't affect touch as much as a newer instrument.
    If SCHAFF still sells Pro-felt, which I used to get from Pianotek, that could soften the hard felt. Or someone on this list may have a recipe for the stuff, seems like I have seen one.
    To adjust the rockers you just need an offset screwdriver. Process is loosen one screw, then tighten the other, and hammer will rise. Takes some patience, but not that hard once you get going. Since the piano was rebuilt, at least you know someone has turned those screws relatively recently. Hope that helps.

    Thanks for the ideas and suggestions . I used Protek CLP on the hammer flanges since most only had 1 to 1 1/4 swings using the swing rest . I have a bottle of Profelt that I will try . Not sure if Schaff sells it but I bought it from Pianotek before they closed

    James,

    Supply 88 has something that I think is as good as or better than VS Profelt. Mark Purney let me test some and it was very good.

    Instead of fussing with chemicals,  replace all felts with the correct thickness and regulate.  Charge accordingly.

    Benjamin, this is not the stuff I tried. That's for verdigris. I looked at the Supply 88 website and didn't see the product I tried. Maybe Mark is still beta testing. Stay tuned!

    I don't see it on their website. Glad you got some. I think it's every bit as good as the VS Profelt. J
