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?

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.

>This morning I tuned a 1924 Ludwig grand with a key leveling system I had never 
>seen before. 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.
