The capstan/fulcrum is on top of a piece of cloth and would seem to wear a lot uicker? Maybe not...as it is sort of rolling, like an upside down accelerated ystem...fine threads on adjustment screw? Did you try to adjust a key? David Ilvedson, RPT acifica, CA 94044 There was no need to adjust any of the keys. I'm not sure it the screws would turn, however, because the piano is old, and many parts are rusted. The piano is not in the best of shape, but it holds it tune.

In each key, in front of the balance rail hole and pin is a screw hat goes through the key. (see picture #1). The other on of this screw is like a apstan screw, which rests on a felt rail, which is the fulcrum of the key. (#2 and 3). The balance rail is used only to keep it from wobbling from side to side. The key eight is adjusted using this screw. >I've never seen a system like this. It's actually quite ingenious, and wonder hy it was not accepted by other manufacturers. It did not feel any difference in how he piano played. Willem (Wim) Blees, RPT Piano Tuner/Technician 94-505 Kealakaa Str.
