Hi,I am working on a 1920s Collard & Collard upright, I am trying to
eliminate the lost motion in the keys but the dollies on the end of the keys
have seized.  I have turned a few of them but they are snapping. I have
reshaped the hammers and am having the same problem adjusting the let off,
the metal parts are just shearing. ....any suggestions?
